Tight games highlight rating chess tournament

JAKARTA (JP): The Kiani Kertas-Enerpac-Tamara Bank Rating Chess Tournament at Wisma Catur Frederick Sumanti on Jl. Tanah Abang I, Jakarta, was a tight and just affair. Many games at the 10-round Schevenigen-system tournament finished in more than forty moves.

The tournament from March 5 to March 15 provided a rare opportunity for Indonesian players to gain FIDE ratings without traveling overseas. Players without FIDE ratings had to play at least nine games against FIDE-rated players.

The FIDE-rated players competed for cash, while the others strove to gain international ratings. Unrated players gained FIDE ratings if their performance ratings were more than 2,005.

Unrated players therefore had to score at least one and a half points to gain a FIDE rating. The latest ratings will be published in the July 1997 ratings list.

The final scores for rated players were first and second NM Nurdin Askali and FM Irwanto respectively on 8 MPs; third-placed NM Kasmiran with 7.5 MPs; NM Haryadi Sucipto with 7 MPs; FM Sukirman Tedy, NM Aris TLS, NM Maksum Firdaus and NM Irawan Tjhin with 5 MPs; and Andreas Susanto and NM Sebastian Simanjuntak with 4.5 MPs.

NM Binsar Marbun came first among unrated players with 6.5 MPs; NM Cecep Kosasih came second with 6 MPs; NM Panathan Hutagaol and Masa Sitepu had 5 MPs; Bambang Kayadi with 4.5 MPs; NM Hendry Jamals with 3.5 MPs; Suhendro Prakata, Agus Salim, PM Hasian Panggabean and NM Tirto with 2.5 MPs.

One the top games of the tournament is described below.

White: NM Sebastian Simanjuntak

Black: Agus Salim

Benko Gambit Defense

1.d4 Nf6 2.c4 c5 3.d5 b5

The Benko Gambit, a sharp opening. Black sacrificed a pawn to get quick results on the queen's side.

4.cxb5 a6 5.f3

This is Utut's favorite move against Gambit Benko. As one of Utut's seconds, of course Sebastian Simanjuntak played the same variant.

5...e6 6.e4 exd5 7.e5 Qe7 8.Qe2 Ng8 9.Nc3 Bb7 10.Nh3 c4 11.Be3!

In game two Utut Adianto-Judit Polgar, in a Jakarta match in 1996, Utut played 11.Nf4 and Black had a better position after 11...Qc5! 12.a4 d4! 13.bxa6 Nxa6 14.Ne4 Qb4+ 15.Kf2 d3.

11...Qxe5?! 12.0-0-0 Be7 13.Qd2 Nf6 14.Bf4 Qf5

Now Black is struggling against White's lead in development. Better would be 14...Qe6!? But it should be examined more closely.

15.g4 Qg6 16.g5 Nh5?

See diagram. A weak move. 16...d4!? is the best option Black has 17.Qxd4 Bxf3 18.gxf6 Qxf6 19.Qxc4 and there are three choices: (a) 19...Bxh1?? Black will regret his greed 20.Qc8+ Bd8 21.Re1+ (21.Bxb8 0-0 22.Be2 Bb6 23.Qxd7 Rd8 and Black wins) 21...Qe6 (no choice, Black will be checkmated if 21...Kf8?? 22.Bd6+ Qxd6 23.Qxd8#) 22.Rxe6+ dxe6 23.b6 White wins; (b) 19...Bxd1 20.Nd5 Qh4 21.Qc8+ Bd8 22.Nc7+ (22.Bxb8 0-0 23.Ndf4 Bf3 Black wins) 22...Ke7 23.Bg5+ Kd6 24.Bxh4 Bg5+ 25.Kxd1 Rxc8 26.b6 (26.Nxa8?! is clearly inferior 26...Rc1+ 27.Ke2 Bxh4; 26.Nxg5?! is clearly worse 26...Kxc7 27.Bg2 f6; 26.Bxg5?! is the weaker choice 26...Kxc7 27.Bg2 d5) 26...Bxh4 27.b7 and White wins; (c) 19...0-0 is the best defense, but after accurate play White is still better, e.g. 20.Bg5! Qe5 21.Bxe7 Qxe7 22.Rg1 Bxd1 23.Qd4.

17.Bxb8??

Hands over the advantage to the opponent. The right move is 17.Nxd5 e.g. (a) 17...Bxd5 18.Qxd5 Nxf4 19.Qxa8 0-0 20.Qe4 Qxe4 (or 20...Nxh3 21.Qxe7 Nf2 22.Rd6 Qh5 23.Rg1 axb5 24.Be2 Qxh2 25.Re1) 21.fxe4 axb5 22.Rg1 Ne6 23.Rd5 White slightly better; (b) 17...c3 18.Nc7+ Kf8 19.Qxc3 Nxf4 20.Nxf4 Qxg5 21.Qe3 axb5 22.h4 Qc5+ 23.Qxc5 Bxc5 24.Re1 Be7 25.Nxa8 White wins.

17...Rxb8

Also good 17...axb5 18.Nf4 Nxf4 19.Bxf4 b4 20.Nxd5 Rxa2 21.Nc7+ Kf8 22.Qe3 b3! threatening 23...c3 and 24...Rc2+ Black wins.

18.bxa6 Qxa6 19.Re1 Kd8 20.Rg1 Re8

Better here 20...Bc5!? 21.Rg4 d4 22.Rxd4 Bxd4 23.Qxd4 Bxf3 24.Bxc4 Qb7 Black wins the Exchange.

21.Nf4 Nxf4 22.Qxf4 Qd6 23.Qxd6 Bxd6 24.Rd1

For 24.Rxe8+!? Kxe8 25.Rg4 Be7 26.Kc2 Ra8 27.a4 f5 28.gxf6 Bxf6 and the Black's Bishop pair dominate.

24...d4 25.Ne4 Bf4+ 26.Kb1 c3 27.b3 Bxe4+ 28.fxe4 Rxe4 29.Rg4 Rc8

Now the position is equal. Better here 29...h5 30.gxh6 (30.Rh4 d5 31.Bd3 Bxg5 32.Bxe4 Bxh4 33.Rxd4 Ke7 34.Bxd5 Bf6) 30...gxh6 31.Bd3 f5 32.Rh4 Bg5 33.Rxe4 fxe4 34.Bxe4 Be3 Black leads one pawn but the position may lead to a draw because of the other colored Bishop.

30.Kc2 Kc7

Here 30...h5!? would keep Black in the game 31.gxh6 gxh6 32.Bd3 f5.

31.Bd3 Rce8 32.Bxe4 Rxe4 33.Kd3 d5 34.Rf1 Bd2 35.Rg3 Re7 36.Rgf3 Kd6 37.h4

37.Kxd4? is no good 37...c2 38.Rc3 Rc7 39.Rxc7 Kxc7 40.Kxd5 Bxg5 41.Rxf7+ Kb6 and Black wins.

37...h6 38.gxh6

38.Kxd4? is worthless because of 38...hxg5 39.Kd3 gxh4. 38...Bxh6 39.a4

39.Kxd4? is worthless because of 39...c2; also 39.Rxf7 Re3+! Black moves ahead of the opponent 40.Kxd4 c2.

39...Kc5 40.a5

If 40.Rxf7 Re3+ 41.Kc2 Re2+ 42.Kd1 d3 43.Rc7+ Kb4 Black wins.

40...Kb4 41.a6

41.Kxd4? is nothing because of 41...c2.

41...Kxb3?

41...f6!? is a viable option 42.Ra1 (42.Kxd4? doesn't lead to anything significant 42...c2) 42...Ra7 43.Rf5 Kc5 44.Ra5+ Kb6 45.Raxd5 Kxa6 46.Rxd4 Bd2 47.Rd6+ White just got a little advantage.

42.Rb1+ Ka2 43.Rb7 Re6

If 43...Re8 44.a7 (44.Kxd4? is inferior since it leads to 44...c2 45.Rf1 c1(R) 46.Rxc1 Bxc1 Black wins) 44...Ra8 45.Rfxf7 White wins.

44.a7 Ra6 45.Rfxf7

White also wins after 45.Kxd4 Bd2 46.Kd3 (46.Kxd5? doesn't work because of 46...c2 47.Rc7 c1Q 48.Rxc1 Bxc1 49.Rf2+ Kb1 50.Rxf7 Be3; also bad 46.Rfxf7 c2 47.Rf1 c1Q 48.Rxc1 Bxc1) 46...f6 47.Rxg7 f5 48.Rxf5.

45...Be3 46.Rf8!

Ending the game.

46...c2 47.a8(Q) c1(N)+ 48.Kc2 d3+ 49.Kd1

Black resigned. 1-0
