Remember GM Oliver Bar­bosa? All Filipino chessers should. In the 40th Chess Olympiad (Is­tan­bul) where the Philip­pines was in the lead deep into the tour­na­ment (we beat Ice­land, Bul­garia drew with Hun­gary and clob­bered Eng­land in suc­ces­sive rounds) Bar­bosa was 2nd board, played in all 11 rounds and scored five wins four draws and two losses.

That was one mem­o­rable Olympiad. Our pow­er­ful lineup was: board 1. GM Wes­ley So board 2. GM Oliver Bar­bosa board 3. GM Eu­gene Tor­res board 4. GM Mark Paragua board 5. IM Oliver Di­mak­il­ing This was the last good per­for­mance for our coun­try in the Olympiads, and you may no­tice that our board 1, 2 and 4 have al­ready left Philip­pine shores and live in the USA. Wes­ley has trans­fil­i­ated to the US Chess Fed­er­a­tion, but Oliver and Mark (on pa­per at least) still play for the Philip­pines.

How is GM Oliver Bar­bosa do­ing? He is still only 30 years old ( born Sept. 29, 1986) and ob­vi­ously a lot of suc­cesses lie ahead of him. The prob­lem is that sev­eral years ago the Philip­pine Sports Com­mis­sion cut the al­lowances of many of our top chess­play­ers. This forced sev­eral of our best play­ers, in­clud­ing Oliver, to leave the coun­try seek­ing greener pas­tures.

In­ter­na­tional Grand­mas­ter Richard Bi­toon went to Texas, where an­other Filipino GM, Julio Catal­ino Sadorra, stays.

Grand­mas­ters Mark Paragua and Oliver Bar­bosa wound up in New York where they tried to eke out a life in its tour­na­ment cir­cuit and en­roll chess stu­dents to pay for their daily bills.

Slowly, things started to look up for Oliver. New York has a thriv­ing chess cul­ture and Bar­bosa’s tremen­dous chess strength and very ob­vi­ous tal­ent helped him sign up a lot of pay­ing stu­dents. Then he mar­ried the for­mer Shine Gor­dovez, a Se­nior Fraud Spe­cial­ist work­ing in J.P. Mor­gan Chase & Co. Pre­vi­ous to that she was with the Philip­pine Heart Cen­ter.

Nowa­days he does not play so much but once in a while re­minds all of us just what a strong player he is. I will let him tell you about the 6th Wash­ing­ton In­ter­na­tional.

“The Wash­ing­ton In­ter­na­tional is one of the best or­ga­nized tour­na­ment here in the US. Grand­mas­ters have free ac­com­mo­da­tion and even guar­an­teed min­i­mum prizes, which is why a lot of so a lot of GMs play in this tour­na­ment. I feel lucky to have won this tour­na­ment since there were a lot of higher rated play­ers. Also, I don’t have the lux­ury of time to study and pre­pare top level chess any­more since I am work­ing as a chess teacher here in NY. I would say pre­vi­ous prepa­ra­tions helped me a lot, ex­pe­ri­ence in top level play and me be­ing a very re­source­ful player helped me win this event. I’d like to thank Mr. Mike Rea­gan for or­ga­niz­ing that tour­na­ment, and to my fam­ily and wife for their never end­ing sup­port all the way.”

GM Bar­bosa sent me two of his games from Wash­ing­ton with his an­no­ta­tions. I will show you one today and the other on Tues­day.

His op­po­nent in the fol­low­ing game, GM Eu­gene Perelshteyn is a well-known guy in US chess cir­cles. Orig­i­nally from Ukraine, his fam­ily moved to the US when he was still a child. Born 1980, Perelshteyn was the US Ju­nior Cham­pion in 2000. He has writ­ten two chess books on the open­ing and is the de­vel­oper of the An­droid ap­pli­ca­tion, Chess Ge­nie, a col­lec­tion of puz­zles for tac­tics train­ing.

This is a cru­cial game for me. I remember I played Eu­gene be­fore and I lost so I need to get back to him and this is the per­fect op­por­tu­nity for me.

We’re not go­ing for crazy Si­cil­ian lines, let’s go to qui­eter po­si­tions.

Not re­ally the main line though I am try­ing to ar­rive at a par­tic­u­lar mid­dlegame po­si­tion as you will see later in the game. I don’t have much time for prepa­ra­tion nowa­days so it’s a good thing I can use some of my prepa­ra­tions when I was re­ally ac­tive on tour­na­ment play.

Iso­lated pawn! It’s con­sid­ered a weak­ness most of the time but this game shows the good points of hav­ing one.

No rush in tak­ing the pawn back. 6... Qxd5 7.Nc3 Qa5 8.Bb5+ Bd7 9.Bc4

9...Nf6 10.Qb3 0–0 11.Bxf7+ (11.Qxb7? Bc6 12.Qxe7 Bxf3 13.gxf3 Nc6 14.Qc5 Qxc5 15.dxc5 Nd4 16.Kf1 A bit messy but white should still have the ad­van­tage) 11...Rxf7 12.Ne5 e6 13.Qxb7 Nd5 14.Nxf7 (14.Qxa8 Bxe5 15.dxe5 Qb6 gets white’s king and queen both in trou­ble) 14...Nxc3 15.Nh6+ Bxh6 16.Bxh6 Nb5+ 17.Bd2 Qb6 Black is slightly bet­ter;

9...Qb4 10.Qe2 Nf6 11.0–0 0–0 12.Bd2 White has a slight ad­van­tage.

Now this is the po­si­tion I’m try­ing to reach. An iso­lated pawn. One of the pos­i­tive points of hav­ing an iso­lated pawn is that you have more space and more ac­tive pieces and hav­ing said that of course I would make use of my pieces to cre­ate an at­tack rather than trade them.

Rooks should be on open or half open files.

Hav­ing an iso­lated pawn on the side is bet­ter than hav­ing an iso­lated pawn at the cen­ter.

Pre­vents Ne4 from black and also threat­ens the g6 pawn if ever black de­cides to kick my ac­tive bishop on g5.

Cen­tral­iza­tion! This move also re­stricts black from mov­ing his f8 rook.

I think this is a crit­i­cal point in the game. Both sides have fin­ished their de­vel­op­ment and it’s time for some plan­ning. The com­puter en­gine sug­gests h3 but of course I think it would hurt my po­si­tion much if I play it out to h4 and maybe later play h5 weak­en­ing black’s king­side for­ma­tion.

This is a mis­take I cal­cu­lated and hoped that he would fall for when I played 17.h4. There are two al­ter­na­tives here.

First is 18...Nf6, a move that is hard to ac­cept but it is more about provo­ca­tion, tempt­ing me to play c4 and block my own bishop. 19.Qe3 Nd7 20.h5 keeps an edge though.

Af­ter 18...Nb4 the con­tin­u­a­tion would be 19.Qd2 (19.Qh3 Nc6 with a rep­e­ti­tion) Nc6 20.Nxc6 Qxc6 21.d5 Qc5 22.dxe6 Bd4 23.Be3 and White still has the edge.

Be­fore I start the com­bi­na­tion, ev­ery piece should be work­ing in­clud­ing the bishop on b3.

PO­SI­TION AF­TER 19...BXC5

20.Nxf7! Qxd4 Ev­ery­thing loses: 20...Kxf7 21.Rxe6; 20...Rxf7 21.Rxe6 Qxd4 22.Qxd4 Bxd4 23.Rxe7 Bxf2+ 24.Kh2 Rcf8 25.Bh6 and ev­ery black piece falls apart.

Later on, I de­ter­mined that 21.Bxe6 was more ef­fi­cient. I had ac­tu­ally thought of this move but stopped af­ter 21... Qxd3 22. Ne5+ Kh8 23. Nxd3 Rc7 (23...Rce8 24.Bd7) 24.Rxc5 Nc6. I should have thought about it a bit longer for then I would surely have seen 25.Bf4 Re7 26.Bd6 and wins eas­ily.

Now, wher­ever the rooks goes, it ends up get­ting cap­tured by the knight’s dis­cov­ered check.

[27...Rxh4+ 28.Bh3 wins]

In­ac­cu­rate! even though I’m still win­ning one shouldn’t miss op­por­tu­ni­ties like this. Cor­rect was 28.Re8+ Kg7 29.g3!

We have run out of space so you will have to wait till Tues­day to see the other game Oliver an­no­tated.
