Under Construction: Links
Hi.
For taday, I have added educational forum links which will help us all check out ideas floating in the education world, thru the cyber space. As time goes on, Creative Ed Interventions will add more of the links we feel important and worth read.
Update on the paperworks: Almost all the necessary infos for the registration of business names and getting the permits required locally and from the BIR is now in the hands of our Managing Director, Ms. Claire SD-B.
More work is needed. We're existing online and on paper. Work, work, work!

Fatal draws
Hi there!
Yesterday, I got the news report from Marlon about FM candidate Paolo Del Mundo beating GM Mark Paragua but only read it today. I wanted to call this post as "homegrown meets ateneo-bred" but when I read the whole article, I was surprised to find out GM Mark P agreed to a draw in 5 moves against IM Finegold in round 4.
Opening draws? Wow! GM level at that... Sayang ito! Mark could have won that game and had a different tournament result.
As for Paolo, he's back in form and it will take only a little while before he gets that GM title. Philippines has the talent, but I dont think we have the managerial skills present in the organizational level of the sports. At least thats how people view it now.
I don't think financial issue exists because the govenrment, thru the Philippine Sports Commission has alloted money for the sports and chess is one of them. Ok, assuming it is not enough, the dough, the bread, we can always ask for corporate sponsorship. You know, these corporate institutions are looking for outreach activities and chess is a good thing for them. We simply have to send them a letter, a proposal. Probably meet up with them. Even my grade 10 students are doing these "sponsor-me-in-this-school-project-of-mine" find ways and actually succeed in doing so.
Anyways, my wishlist:
1. Bobby Ang heading the NCFP!
2. Manny Benitez with him
3. All things emanating from the two.
4. The rest, followers!
5. Oopps! Not to mention the professionally-run CAAP, the people behind them!
6. Media coverage is a must! CJAP can take care of this.
7. NCFP Rating tournaments. The best way to introduce people to chess and keep them in the fold is to give them ratings. This will motivate them.
8. Chess Caravan should be continued.

FIDE master candidate Anton Paolo Del Mundo demolished Grandmaster Mark Paragua in the fifth and final round to tie at first along with three others in the recently concluded 39 th annual Atlantic Open, a top chess event held in Westin Hotel in Washington DC last August 24-26.
Del Mundo tied for first with three others, IM Benjamin Finegold, IM Mikhail Zlotnikov, and US Master Chris J. Mabe. They scored 4 points in 5 rounds. Each of them received US$1,200.
Del Mundo has topped three notional chess events in a period of two months. He emerged co-champion of the Under 2400 Section at the World Open starting July, and followed that up with the feat of being the first Filipino to win the US Open, a prestigious event held for the past 108 years, and before August ends, the Atlantic Open. This is perhaps the best consecutive performances by a Filipino in mainland US.
Paragua, the country's ranked No.3 who possessed an Elo rating of 2525 showed a strong performance with 3.5 points out of 4, and had the chance to be the solo champion except for a sorry loss in the final round to Del Mundo. He drew with eventual co-champion IM Finegold in 5 moves in the fourth round, which proved fatal because of the unexpected loss.
The big chess event in DC was well-attended, and strong players like IM Emory Tate, IM Brian Smith, IM Justin Sarkar among 97 players in the Open were out of contention before the last round.(MARLON BERNARDINO).

Idealism and Power
Hi there!
When we were young, we had all the idealism in our heads and in our veins. Now that we're full of responsibilities, 24-7's not enough. We've gained power but lost time and vision of our youthful ideals.
Take this scenario: Over 100 chess ebooks falling on my lap, like the manna from heaven. Checking it out overnight, one can't help but wonder why on earth I have a lot of resources and so limited time to devour on it? So many things to do, so little time I've got.
Am not complaining about the resources. In fact, I consider the person giving these to me as a gift from heaven. A gift not just for me but to all those students I've got in my club so thirsty of chess knowledge.
This guy once told me that he is simply giving back what chess has given him and his loved ones. He was a board 2 player in one of the tertiary institutions in our land, he was "regularized" in the company that he works for becasue of chess. And his kids are on an athletic scholarship because of chess, and doing great at that.
Caution though, these secret ebooks are not to be given away. Main reason is that enterprising chess players will earn without a sweat by simply burning copies of the cd's and selling them to other players. This guy has put in internet time and effort to have them compiled. Now comes the piracy thing right? You would'nt want those precious sleepless hours be greedily taken advantaged of by some income conscious individuals right?
Anyways, when I said over 100 books, I meant around 150 e books. This guy even asked me to make sure I sleep well at night rather than read them all up. Hahahahahah! Thank you so much!

And yes, I do remember Paolo. In fact, I've been looking for him in the local and international tournaments held last year by the NCFP. Paolo is a chess treasure. In this day and age where IQ and EQ is at the peak of its integration to the human system, I believe this guy is the man, The Man.
Idealism and Power? Wesley and Hari? sounds good? No politicking please!

ANOTHER R.P. DISASTER IN THE MAKING?
ALL four leading Filipinos were knocked out of contention for a major prize in the eighth round of the Dato Arthur Tan Open in the ongoing Malaysian Chess Festival in Kuala Lumpur on Friday.
At the head of the field of 87 players was a 21-year-old Chinese candidate master, Zhou Weiqi, eighth-round conqueror of Filipino IM Barlo Nadera, followed by Chinese NM Li Chao. They had 6.5 points each.
Behind them with 6.0 each were the top seed, GM Zhang Zhong and WGM Li Ruofan, both of China, GMs Dao Thien Hai of Vietnam and Ziaur Rahman of Bangladesh and IM P.D.S. Girinath of India.
IM Wang Rui of China. IM Ronald Bancod of the Philippines. GM Nguyen Anh Dung of Vietnam. IM Irwanto Sadikin of Indonesia, Wang Li of China and FM Lim Ye-Weng of Malaysia followed half a point behind.
The four Filipinos knocked off from their high perch were IMs Nadera, Oliver Dimakiling and Richard Bitoon along with NM Emmanuel Senador.
Not one of the five Filipino grandmasters showed up.
The four had 5.0 points each after the seventh round and were within striking distance of the leaders when they met their Waterloo at the hands of Vietnamese, Chinese and Indian masters
Dimakiling lost with White and Senador with Black to Vietnamese GMs Nguyen Anh Dung and Dao Thien Hai, respectively, Nadera with Black to Chinese NM Zhou Weiqi, and Bitoon with Black to Indian IM P.D.S. Girinath.
All four slid down to the 15th to 19th slots with 5.0 each along with FM Hamed Nouri who joind them after defeating Malaysia’s Ahmed Ismail in the eighth round. Nadera, Dimakiling, Nouri, Senador and Bitoon were tied for the 15th to 23rd slots with three Indonesians and one Chinese.
This left only IM Bancod among the nine Filipinos with a chance at No. 10 of catching up with the leaders.
Bancod, who had beaten Malaysian FM Anis Nazreen Bakri with Black, entered the ninth with 5.5 points and was to face Vietnamese Nguyen Anh Dung with Black again.
Three other Filipinos—IM Julio Catalino Sadorra and NMs Rolando Nolte and Rhodel Legaspi—had 4.5 each, along with GMs Murray Chandler of England and Utut Adianto of Indonesia as well as Australian IM Gary Lane, among 11 others in a tie for the 24th to 39th slots with three more rounds to go.]

Two Pinoys grab lead in AmBank Challenge in KL
TWO Filipinos have seized the lead along with a Malaysian player in the cash-rich AmBank Challenge for non-masters in the Malaysian Festival in Kuala Lumpur.
Allan O. Cantanjos, Jerry Nodado and Che Hassan Abdullah of Malaysia led the field entering the ninth round of the non-masters event.
Cantanjos and Nodado faced each other in the eighth round and agreed to a peaceful draw.
In the ninth, Cantanjos was to play White against Chrisopher Castellano while Nodado was up against Alberto Rivera in an all-Filipino duel at the top.
Just half a point behind Cantanjos and Nodado was yet another ranking Filipino non-master, Roel A. Abelgas.
Filipino players also dominated this non-masters event last year.
Bartolome, Pilarta rule S. Luzon leg of Shell series
GIVY BARTOLOME of Colegio de San Juan de Letran-Calamba in Laguna captured the Junior Division title in the Southern Luzon leg of the Shell National Youth Active Chess Championship held recently at SM City Batangas (see pictorial on page 3).
He and James Ryan Fernandez of the University of Nueva Caceres qualified for the Shell Grand Finals to be held in October. Arvin Dableo of Philippine Maritime Institute was just behind them.
In the Kiddies Division, Wilbert Pilarta of Maris School ruled the roost, followed by Gilbert Mejia of Colegio de San Juan de Letran and Mark Anthony Trinidad of Gen. Pio del Pilar-Makati City.
Meanwhile, the University of Batangas received a special award for having the biggest number of participants in both divisions –27 in the kiddies and 30 in the juniors.

Shell series draws 377 to Batangas leg
HUNDREDS of chess lovers, including 377 players, trooped into SM City Batangas as soon as the shopping mall opened, to take part in or watch the recent two-day Southern Luzon leg of the Shell National Youth Active Chess Championship, a popular series in the grassroots now on its 15th year as a nationwide sport.
They were welcomed in a simple opening ceremony by Robert Malabanan, external affairs manager for Shell Batangas, who introduced Luz Amparo, representative of Batangas City Mayor Eduardo Dimacuha.
In her inspirational talk, Ms. Amparo thanked Pilipinas Shell for sponsoring “this activity that encourages our young people to hone their skills in chess to become champions someday.”
“You are the cadre of young people whom we will look up to as leaders of our country,” she told the players.
Sunny days for Salvador in Italy
IT looks like Roland Salvador, 2000 Shell Youth National Active Chess champion, made the right move when he left home over a year ago to try his luck in Europe in his quest for the elusive grandmaster title.
Already, he has achieved two GM results and now needs only one more to become a GM and his Elo rating of 2461 is bound to go up as he finished second in the latest tournament he entered, the popular Bergamo tournament a few miles from his base in Milan, Italy.
As reported three weeks ago in The Weekender, Macedonian GM Vladimir Georgiev took the first slot with the young Bulakeño international master tying for second place with three others.
They were GMs Todor Todorov of Bulgaria and Viesturs Meijers of Latvia and IM Inna Gaponenko of Ukraine.
Salvador, who earned his IM title only recently, took the second slot on tiebreak.
Behind them were four other GMs from Eastern Europe—Sergei Krivosky of Ukraine, Sinisa Drazic and Miroljub Lazic of Serbia, and Milko Popchev of Bulgaria, along with one Italian IM, Maurizio Brancaloni, Salvador’s compatriot, IM Rolly Martinez, Moldovan WGM Karolina Smokina and an Italian master, Mauro Barletta.
The Bergamo tournament, held annually in the Italian city, drew 125 participants from all over Europe.
That most of the heavyweights came from East European countries that used to be within the Soviet sphere of influence indicates it was a very tough tournament. It’s a pity Salvador did not earn his third and final GM title in that tournament.
On the other hand, the consistently excellent results that the 25-year-old Filipino IM has achieved in Europe against tough opposition shows beyond doubt that he is ready to capture the title. The Weekender will only be too glad to report such eventuality, hopefully in the near future.
Indeed, as featured in the Kibitzers’ Corner of the website Chessgames,com, Salvador has fired the imagination of many Filipino fans that have been following his career since he, Martinez and IM Yves Rañola left the country last year.
We can only hope that after he captures the coveted GM title, Salvador will come back home and inject new life into Philippine chess. It’s about time the younger players took over from their elders. Sad to say, it has been a very slow process, producing young grandmasters.
One positive thing I have noticed about Salvador’s play is that he seems to be comfortable with either color. Most of his fine wins were with Black, such as in this model of a game in which he chases the enemy queen into a cul-de- sac!

Total of 34 teams
Did I read the final standings right? Did the Philippines, the 22nd-seeded team, just win the bronze medals in a world team competition? Is it true that India was running away with the competition but got dumped 1-3 by the Philippines? And could it be possible that our team of kids had great chances to win it all, but tired in the last three rounds? Finally, was I dreaming or did Wesley So, playing without relief, top the individual standings in all three categories (percentage, performance rating and overall points) by beating nine and allowing only one draw in the 10 rounds. Are you kidding me? Did Wesley So register a performance rating of 2736?
No, I read right, it is true, it is possible, I was not dreaming and no one is kidding me - the Philippine team did all that.
We defeated Switzerland (3-1), England (2.5-1.5), Sri Lanka (4-0) in the first three rounds, lost to Hungary (1.5-2.5) in the 4th, reeled off another three straight wins (2.5-1.5 against Iran, 2.5-1.5 vs Uzbekistan, and then came the giant 3-1 upset over India).
With three rounds left we were just trailing front-runner India by a single point, but fatigue set in and we fell behind again when Singapore and Australia held us to 2-2 draws. Moreover, Hungary with two successive 4-0 shutouts (over Switzerland and Uzbekistan) by this time had overtaken us for 2nd place.
A final-round 2.5-1.5 victory over Turkey was not enough to bridge the gap, and the Philippines came home with the bronze medals.
On individual results Wesley So won the gold medal on top board with a stupendous 9.5/10 (!). Haridas Pascua on board 3 won the silver with his 7.5/10.
And guys, listen to this – both Wesley and Haridas are only 13 years of age, playing against kids 2 or 3 years older.
Finishing third in this event could not be anything but a great success. Let us celebrate this fine finish, for our pre-tournament seeding was 22nd, and let us bask in this glory that our young prodigies have brought us. At least, among the young, where raw talent rather than studied technique is at the forefront, the Philippines has once again reminded everybody that we are a force to reckon with.
Here is Wesley defeating India’s top board:
So,Wesley (2516) - Adhiban,Baskaran (2406) [C30]

1.e4 e5 2.Bc4 Nf6 3.d3 Bc5 4.Nc3 Nc6 5.f4 d6 6.Nf3
The Wesley Formation, which is actually a King's Gambit Declined.
6...Bg4 7.Na4 0–0 8.Nxc5 dxc5 9.0–0 Nh5 10.Be3
A new move, to which Adhiban does not respond properly.
10...exf4?!
[10...b6 is refuted by 11.Bd5, but the correct continuation was 10...Qd6 11.f5 Nd4]
11.Bxc5 Re8 12.h3 Bxf3 13.Qxf3
Black now has to be very careful, for white has two bishops trained on the black king, and his f7 is weak.
13...g6 14.Bd5 Ne5 15.Qf2 c6 16.Bb3 b6 17.Bd4 Ng3 18.Rfe1 g5
Black has managed to keep the f-file closed, but Wesley has another plan in mind now, first Bc3, then Rad1, then d3-d4, and the pawns advance.
19.Bc3 Qd7 20.Rad1 Rad8 21.a4 c5 22.a5 c4 23.Bxe5 Rxe5 24.Bxc4 Rxa5 25.d4 b5 26.Bb3 Ra6 27.d5 Rh6 28.e5 Qf5?
Loses immediately, but Black was tired of waiting for where White would break through and attempts to create some threats against the enemy king.
29.Qf3 Rh4 30.Rd4 a5 31.e6 fxe6 32.dxe6 Re8 33.e7+ Kg7 34.Qc3 Qf6 35.Rd8 Qxc3 36.bxc3 1-0
Adhiban has to give up the rook for a pawn, and so he gave up.
Here is the best game of the other 13-year old.
Pascua,Haridas - Nitin,S (2313) [A44]
World Youth U16 Olympiad (7), 08.08.2007
1.d4 c5 2.d5 d6 3.c4 e5 4.e4 g6 5.Nc3 Bg7
The Czech Benoni. This opening falls into the same category as the Dutch or the Kings' Indian Attack for White - it is good as a fall-back-on opening, but don't play this all the time, for it stifles creativity - the same moves over and over game after game.
6.Be3 Ne7 7.Bd3 f5
Having achieved this move without much resistance Black is perhaps already thinking that he is about to seize the initiative. White has something to say about that.
8.f3 Nd7 9.Qd2 h6 10.g4 fxg4
Given his incomplete development Black would be better-advised to keep the position closed with 10...f4.
11.fxg4 Nf6 12.g5 hxg5 13.Bxg5 Bg4 14.Qg2 Bh5 15.Nge2 Nh7 16.Be3 0–0?!
A courageous, but ill-advised move. Most people would go for castling queenside with ...Qb6 and ...0–0–0.
17.Rf1 Rxf1+ 18.Kxf1 Qd7 19.Kg1 Bg4 20.Ng3 g5?
[20...Bh3 is the indicated move]
After 20...g5
21.Nf5! Bxf5 22.exf5 Kf7
[22...Nxf5 sets up the enemy knight for a deadly double pin with 23.Qh3]
23.Ne4 Rh8 24.f6! Nxf6
[24...Bxf6 25.Rf1]
25.Rf1 Neg8 26.Bxg5 Qh3 27.Nxd6+ Kf8
[27...Ke7 doesn't help: 28.Nf5+ Kd7 29.Qxh3 Rxh3 30.Nxg7 Rxd3 31.Bxf6 Nxf6 32.Rxf6]
28.Qxh3 Rxh3 29.Bf5 Rh5 30.h4 Ke7 31.Nxb7 Bh6 32.d6+ Kf7 33.d7 Bxg5 34.d8Q Bxh4 35.Nd6+ Kg7 36.Qc7+ 1–0
I notice that some readers have complained why Wesley So was fielded here, why he was not concentrating on getting his 2nd and 3rd GM norms. That is the wrong attitude. Getting norms was never the point of joining the World Team Under-16 Championship—the more important goal of glory to the Philippines is what should be considered, for right now we are sorely lacking in heroes.
Congratulations to our new heroes!

Paolo del Mundo
THE US Open Championship is an open national chess championship that has been held in the United States since 1900. It is an “open” event, meaning anyone can join, as opposed to the U.S. Closed Championship, which is an invitational.
This year’s edition took place in the Crown Plaza Philadelphia-Cherry Hill, NJ July 28 - August 5th 2007.
1-7 GM Boris Gulko 2576, GM Sergey Kudrin 2543, IM Ben Finegold 2543, GM Alexander Shabalov 2637, GM Michael Rohde 2450, IM Michael Mulyar 2373, Paolo del Mundo 2296, 7.5/9
8-18 GM Hikaru Nakamura, IM Amon Simutowe, IM Alex Lenderman, IM Mikhail Zlotnikov 2367, IM Dean Ippolito 2395, Alexander Barnett 2235, Ronald Henry 2161, Abby Marshall 2177, Andy May 2099, Naor Brown, GM Tegshsuren Enkhbat 2371, 7.0/9
Total Participants: 414
Our good friend, veteran journalist Manny Benitez, tells me that with this victory Paolo becomes the first Filipino to tie for first in the US Open Championship. I was skeptical about this, since to my knowledge IM Ruben Rodriguez was co-champion in the 1973 edition, but a search through my usual sources does not show any of the official sources list him as such. Anyway, whether the first or the second actually should not matter, for Paolo has achieved what even the top Filipino GMs have never done.
Do any of you guys still remember him? In 1999 the Del Mundo family left the Philippines for good, and Paolo, who was then 16, with them. High School in Ateneo had already marked him out as an outstanding talent.
Paolo del Mundo
In chess he led Ateneo to four consecutive UAAP chess championships, a 4-peat.
Ateneo rewarded him with the Magis award and the best student athlete in his senior year. This actually made up for the stern discipline they impose on absences and studies. Despite his busy chess schedule, Paolo attained academic honors in his senior year.
At about this time, University of Maryland Baltimore County acceptance came in. The invitation to join the chess team, which he got in his junior year, was not automatic until he passes the academic requirements, which includes grades and SAT scores. His high grades in Ateneo and a SAT score of 1350 got him in, and thus started him as the first Filipino to get a college scholarship through chess in the United States.
Before he started schooling however, he went to the 100th US Open in Reno, Nevada. The tournament was prestigious especially because it attained the century mark, and Paolo went into the records as the first placer in the Under 2200 category.
At UMBC, he took up computer science despite comments from well-meaning people that would exact a toll on his chess game. This writer remembers suggesting that he take up sports journalism, similar to what the top Soviet GMs were taking – this allows them to travel to tournaments in the guise of work! Anyway, I thought Paolo would take up that advice, but it appears that his dad convinced him that writing was already in his blood, so he would probably excel in that if he chooses too even without a college education. At that time, computer science was in
vogue, and seemed to be a promising major, and all well and good as it turned out to be.
Chess has taught Paolo to be rigorous in discipline, and as such even if he found computer science a little tough, he was able to get into its vocabulary and became good at it (graduating with honors once again in his senior year).
Paolo turned out to be a gem in UMBC's two national Pan Am titles, the national collegiate championships, during his stay in the school. He delivered the winning margin for his first Pan Am stint, and was solid on his second one as they won the title in succession.
During these two years, he also won the UMBC Open champion title, for being the highest ranked UMBC student in the competition.
On the third year, Paolo opted to transfer to University of Maryland College Park, which was a more prestigious school and had a livelier social life than UMBC. It was also ranked among the top schools in computer science in both United States and the world.
During these last two years, Paolo's game hibernated but still added prestige to the UMCP chess club. He was able to complete his studies with honors despite the hassles of transferring schools. Chess however was in the back burner as he honed up to graduate as a software engineer.
Upon graduation, he was immediately accepted by Anystream, a sofware development company which served as a third party developer for Microsoft. It was a happy coincidence that he got his next job through chess. He was teaching someone who suggested that he applied with her IT company. Thus he joined Microstrategy, a big firm in Tysons Corner in Virginia.
His next company was Bode Technology, a CSI-like company which specializes in DNA testing and forensics. Paolo was a senior software engineer in Bode. Bode however was acquired by a bigger company, and immediately before the World Open this year, Paolo got laid off because the new company was making budget cutbacks. Paolo was preparing for the World Open at that time, so he just took this in stride, and got his resume in circulation through a headhunter. He was
already making his rounds of interviews. The furlough from work however was a blessing in disguise. Of course, everyone knows already that he won the Under 2400 category, which is actually a new category just placed this year in the World Open. This enticed high rated players like Paolo to compete for the section. Since he was tied for first with five others, Paolo got $6,000 for the one week effort.
The US Open was a bit more problematic. At that time he was playing in the tournament, the companies recruiting him were making offers, and some of them were asking him decide immediately. Since it was distracting Paolo, he decided to tell them to wait and that he would make a decision after the tournament. Only then was he able to play without distraction. This phase coincides with winning all the last five games, and eventually caught up with the leaders to tied for first in the US Open. After the US Open, Paolo accepted his next job. In between jobs, he won two major titles while he was on forced vacation. Think of what he can do if he was concentrating on chess!
Paolo emailed me that here in the US Open he finally found his style. Judging by the ferocity with which he devours his opponents, everybody should take due precautions!
Del Mundo,Anton P (2388) - Vicary,Elizabeth (2155) [A37]

1.Nf3 c5 2.g3 Nc6 3.c4 g6 4.Bg2 e5 5.0–0 Bg7 6.Nc3 Nge7 7.a3 d6 8.b4 cxb4?!

9.axb4 Nxb4 10.Ba3
White has more than sufficient competition for the pawn due to Black's weakness on d6. This position has come up 8 times previously in international competition, including all-GM contests. White has won every single game.

FROM MY SWIVEL CHAIR
NCFP must get its act together
FOR the past few months, since the May elections for that matter, Philippine chess has not been getting the media attention it deserves—and needs—if it is to be a truly popular sport in the country and a potent global force.
In my favorite newspaper, cockfighting even gets more mileage than the “game of kings and king of games.”
Why is this so? Who is to blame?
The answer is obvious: the National Chess Federation of the Philippines has been doing virtually nothing since May to make its presence felt in Philippine sports.
It held a selection tournament for the men’s and women’s teams to compete in the Asian Indoor Games late next month in Macau, true, but how many newspapers and radio and TV stations carried the story? Ask the ordinary man in the street who won the tournament, and chances are, he would not know.
Nobody in fact knows who runs the NCFP. Has anybody heard NCFP president Prospero Pichay say or do anything as regards Philippine chess?
Has anybody read the latest issue of Chessmates? Has the Pichay Chess Caravan continued rolling around the countryside? Has there been a major national tournament besides the one for Macau? Does anybody know who the NCFP board directors are? Will the board ever meet again?
In fairness to chess players and fans, the NCFP must at least resume its activities as laid down in its yearly calendar. Butch Pichay must categorically state in public whether or not he wishes to remain as NCFP president and to back it up with action by “making the right move.”
It is only a matter of the NCFP’s getting its act together. Despite its lackadaisical performance, Philippine chess is going great guns.
As pointed out by Bobby Ang in his column (see pages 12-15), Philippine chess has its young heroes like Wesley So, Karl Victor Ochoa, Haridas Pascua and Franz Grafil who, against all odds, won individual gold and silver medals and the team bronze at the Youth World Olympiad held last month in Singapore.
They are our young heroes, and there are scores more waiting in the wings, potential champions among the prodigies in both genders.
A few Filipinos who have gone to seek their fortunes abroad have been doing well. Enrico Sevillano and Paolo del Mundo in America, Joseph Sanchez, Rolly Martinez and Roland Salvador in Europe—they have all done us proud.
Because of the big letdown caused by the NCFP’s lack of leadership, the exodus will certainly continue. In fact four of our five grandmasters are out of the country right now.
Joey Antonio and Macmac Paragua are both in the US while Bong Villamayor and Nelson Mariano are in Singapore. Only Eugene Torre, who will turn 56 in November, is left to man the fort.
What Joey said to explain why he would rather play in the US than here should serve as a wake-up call to us all: “There are no tournaments back home anyway!”

And yes, I do remember Paolo. In fact, I've been looking for him in the local and international tournaments held last year by the NCFP. Paolo is a chess treasure. In this day and age where IQ and EQ is at the peak of its integration to the human system, I believe this guy is the man, The Man.
Idealism and Power? Wesley and Hari? sounds good? No politicking please!

E-C Openings
Hi there!
Whew! Three posts in a day...
Before I retire, I wanted to find out about The London System, Torre Attack adn The English Opening. For sometime now, almost a year, I have always used c4 for my opening as white and c5 for black. I've been succesful somehow with the two. I thought I could give a good research on this but found out though it has a lot of variations which leads to different openings. I believe I am not ready to study such wide variation possibility. Too much for me.
Then I remember what Mr. Ex Bolico told me during the 3rd Xavier Interscholastic Chess Invitationals. Teach the Torre Attack to your students. I asked why, of all openings, why this one. He says "It is simple, easy to set up and has a limited variation (2?) which is good for scholastic chess. I said, if it applies to my students, then it applies to me too. Right?
And last week, during the stormy days, I attended and actually presided the Imus Chess Association's meeting, preparign for the Cavite Inter-town Chess Team Tournament. I was lucky enough to have asked one of our players, Coleen, on the best opening to teach among the elementary school graders. He said " The London System is okay..." Before finishing, I interrupted him and asked if he agrees with Mr. E of La Immaculada Concepcion School -Pasig. He agreed too.
So now, I took my pencil and paper and copied from The Wikipedia. I didn't bother copying the English opening since it is too much... yes, not for me to study.
Then I realized, I could simply type in Chess Openings for my keyword search. And then Kaboom! Chessville provided my a word document for the entire chess openings man has invented to rule the game.
Here it is:

Whew! Three posts in a day...
Before I retire, I wanted to find out about The London System, Torre Attack adn The English Opening. For sometime now, almost a year, I have always used c4 for my opening as white and c5 for black. I've been succesful somehow with the two. I thought I could give a good research on this but found out though it has a lot of variations which leads to different openings. I believe I am not ready to study such wide variation possibility. Too much for me.
Then I remember what Mr. Ex Bolico told me during the 3rd Xavier Interscholastic Chess Invitationals. Teach the Torre Attack to your students. I asked why, of all openings, why this one. He says "It is simple, easy to set up and has a limited variation (2?) which is good for scholastic chess. I said, if it applies to my students, then it applies to me too. Right?
And last week, during the stormy days, I attended and actually presided the Imus Chess Association's meeting, preparign for the Cavite Inter-town Chess Team Tournament. I was lucky enough to have asked one of our players, Coleen, on the best opening to teach among the elementary school graders. He said " The London System is okay..." Before finishing, I interrupted him and asked if he agrees with Mr. E of La Immaculada Concepcion School -Pasig. He agreed too.
So now, I took my pencil and paper and copied from The Wikipedia. I didn't bother copying the English opening since it is too much... yes, not for me to study.
Then I realized, I could simply type in Chess Openings for my keyword search. And then Kaboom! Chessville provided my a word document for the entire chess openings man has invented to rule the game.
Here it is:
