MT Sustarsic: Draw against GM Kögler, Klaus

Draw against GM Kögler, Klaus of Germany: http://www.iccf-webchess.com/MakeAMove.aspx?id=297381 . He is 47 years old, working as a freelance translator and writer. The game:

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nge2 O-O 6.Ng3 a6 7.Be2 c5 8.d5 b5!?

Black chooses active play with a pawn sacrifice.

9.cxb5 axb5 10.Bxb5 Ba6 11.O-O Bxb5 12.Nxb5 Ne8

ChessOK opening tree gives only 13.Qc2 Na6 14.Ne2 Nec7 15. Nbc3 Qd7 {1/2-1/2, Serper Grigory (USA) - Smirin Ilia (ISR), Philadelphia (USA), 1996}


13.a4 Nc7 14.Na3 Ra6 (N)

Black chooses to vary. 14...Nd7 15.Nc4 Ne5 16.Ne3 Qb8 17.Rb1 Qb7 18.Bd2 f5 19.exf5 Nxd5 20.
Qc2 Nxe3 {1-0(44) Rawlings, Alan J. C (2334) - Le Page, Claude (2361)
/ WS/MN/057 (?), ICCF 2010}

15.Rb1 Nd7 16.b3 Qa8 17.Bb2 Bxb2 18.Rxb2 Rb8 19.Qc2 e6 20.dxe6 Nxe6 21.Nb5 Nd4 22.Nxd4 cxd4 23.Ne2 d3!?

This leads to simplifications.

24.Qxd3 Nc5 25.Qd2 Nxb3 26.Rfb1 Nxd2 27.Rxb8+ Kg7 28.Rxa8 Rxa8

We reach an ending, where White is a pawn up. But can he convert to a win? That is the vital question.

29.Rb4 f5 30.f3 fxe4 31.fxe4 Re8 32.Ng3 

Was 32. Nc3 better?

32...Rc8 33.Kf2 Nc4 34.Ne2 Kf6 35.Nc3 Ke5 36.Ke2 Ne3 37.Kd3 Nxg2 38.Rb5+ Ke6 39.Nd5 g5 40.Nb6 Nf4+ 41.Kd2 Rc7 42.Rxg5 Ng6 43.Rh5 Ne5 44.Rh6+ Ng6 45.Rh5 Ne5 46.Nd5 Rc4 47.Nc3 Nd7

Now White is two pawns up, but he cannot maintain it. Unfortunately, he is saddled with two rook pawns, which is very drawish.

48.Rxh7 Nc5 49.a5 Rd4+ 50.Kc2 Rc4 51.Rh4 Ke7 52.h3 Kd7 53.Rg4 Na4 54.Kb3 Rxc3+ 55.Kxa4 Kc6 56.h4 Rc5 57.Rg5 Rc4+ 58.Kb3 Rxe4

We reach a seven man position, which appears to be a draw.

59.h5 Rh4 60.Kc3 d5! 

Only move to draw?

61.a6 d4+ 62.Kc4 Kb6 63.Rg6+ Ka7 64.Rh6 Rf4 65.Rd6 Rh4 66.h6 Ka8 67.Rd8+ Ka7 68.Rd6 Ka8 69.Rd8+

And now I offered the draw, which was accepted.

1/2-1/2

With this game, I completed all games to jointly win the tournament along with Šivic, Jernej of the host nation, Slovenia. And strangely, both our SB scores are identical, and our wins were against the same players, so I don't know what tie-break can be applied. Here is the crosstable:

Israeli championship 49: Win against SIM Jędrzejowski, Maciej

Win against SIM Jędrzejowski, Maciej of Poland: http://www.iccf-webchess.com/EventCrossTable.aspx?id=20623. Maciej is 46 years old, working in his own small trade firm. The game:

1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c6 5.e3 Nbd7 6.Qc2 Bd6 7.g4 dxc4 8.Bxc4 e5 9.g5 Nd5 10.Bd2 exd4 11.Qe4+ Ne7 12.Qxd4 Nf5 13.Qe4+ Ne7 14.Qc2 Nb6 15.Be2 Bf5 16.Ne4 Bc7 17.O-O-O

The ChessOK opening tree only considers 17. Nh4, 17. Nd4 and 17. Bd3.

17... O-O 

17...Qd5 18.Nc3 Bxc2 19.Nxd5 Nexd5 20.Kxc2 O-O-O 1/2-1/2(54) Nylander, Eric (2458) - Mannermaa, Dr. Jari (2502) / II Nordic Club Team Championship (?.1), ICCF 2007

18.Bd3 

18...Qd5

I was wishing for 18...Bg4 19.Nf6+ !


19.b3 Ng6 20.Nd4 Bh3 21.Rhg1 Rfe8 22.Kb1 a5? 

 22...Bxh2+  23.Rh1 Bg2 24.Nc3 Qe5 25.f4 Bxf4 26.exf4 Qxd4 27.Bc1 Nd5 28.Nxd5 Qxd5 29.Bxg6 hxg6 30.Rxd5 Bxd5 31.Qh2 Be4 32.Ka1 Bxh1 33.Qxh1 leads to forced simplification where it is not clear whether White's advantage is sufficient for a win.


22...Be5 seems OK for Black.

23.Nc5 a4 24.b4 Be5 25.Bc3 Nc4 26.Ka1 b6 27.Be4 Qd6 28.Nxc6 Na3 29.Qb2!

Now, once again we have a forcing sequence at the end of which White wins a pawn.


Bxc3 30.Qxc3 Nb5 31.Qc4 bxc5 32.Qxb5 Qf8 33.Bxg6 fxg6 34.Qxc5 Qxf2 35.Qd5+ Kh8 36.Qd2 Qf5 37.Rc1 Re4 38.Rc5 Qf8 39.Rc3 Bf1 40.Nd4 Re5 41.h4 Rae8 42.Rh1 Kg8 43.Rh2 Qd6 44.a3 Qd5 45.Qc2 h6 46.Qxa4 Rxe3 47.Qb3 Qxb3 48.Rxb3 R3e4

 After this, White's connected passed pawns assure the victory. 


49.Nf3 Be2 50.Rc3 Rd8 51.Kb2 Rd5 52.Kc1 Re7 53.Rg2 Kh7 54.Nd2 Rd4 55.Rh2 h5 56.Rc5 Bd3 57.Nb3 Rg4 58.Kb2 Bf1 59.Rc8 Bg2 60.b5!

 All engines were against this move, but I realized that the position after 65...Rxh4 is won for White. 


60...Rb7 61.a4 Rxa4 62.Rxg2 Rxb5 63.Rc5 Rbb4 64.Rh2 Rxh4 65.Rxh4 Rxh4


The position whose evaluation was critical.

66.Nd2 Rh3 67.Rc3 Rh2 68.Kc2 Rg2 69.Rc5 Rg3 70.Ne4 Ra3 71.Rc7 Kg8 72.Nd6 Kf8 73.Rf7+ Kg8 74.Re7 Ra8 75.Kd3 h4 

Now, this pawn will be lost. Rest is a matter of time.


76.Kd4 Rd8 77.Kd5 Rf8 78.Re3 Rf1 79.Ke5 Rg1 80.Kf4 Rd1 81.Ne4 Rg1 82.Rh3 Rf1+ 83.Ke5 Rf5+ 84.Ke6 Rf4 85.Nd6 Ra4 86.Rc3 Ra8 87.Rc4 h3 88.Nc8 h2 89.Ne7+ Kf8 90.Nxg6+ Kg8 91.Rh4 Ra6+ 92.Kf5 Ra5+ 93.Ne5 Ra2 94.Nf3 Ra5+ 95.Kg6 Ra3 96.Nxh2 Ra6+ 97.Kh5 Kh7 98.Rb4 g6+ 99.Kg4

1-0

With this win, I win the championship, irrespective of the result in the remaining game. The crosstable:

MT Sustarsic: Win against SIM Gaprindashvili, Paata Amerigovich

Win against SIM Gaprindashvili, Paata Amerigovich of Georgia. He is 48 years old, beekeeper, playing correspondence chess since 1990. He is also author of the books:
a) Imagination in Chess: How to Think Creatively and Avoid Foolish Mistakes
b) Critical Moments in Chess

1.Nf3 Nf6 2.g3 d5 3.Bg2 c5 4.O-O e6 5.d3 Nc6 6.Nbd2 Be7 7.e4 O-O 8.Re1 Qc7 9.e5 Nd7 10.Qe2 b5 11.h4 Bb7 12.Nf1 a5

12....Rac8 is popular, but the ChessOK opening tree shows 60 % White wins and only 15 % Black wins out of 20 games. Hence I chose an offbeat move.

13.Bf4 a4 14.a3 Qb6

14...Nd4 15. Nxd4 cxd4 16. Nh2 Rfc8 17. Rec1 b4 18. Nf3 Qb6 etc 1-0, Jurkovic Ante (CRO) - Podkriznik Gregor (SLO), Bled (Slovenia), 2000 and 14. ... c4 15. Ne3 Qb6 16. Ng4 Kh8 17. Ng5 Nd4 18. Qd1 Nf5 19. Ne3 Bxg5 20. hxg5 Nxe3 21. Bxe3 Qc7 22. d4 c3 etc and 1-0, Herndlbauer Martin (AUT) - Jirovec Alfred (AUT), Austria, 2001 are the two alternatives given by the ChessOK opening tree.

15.N1h2 c4 16.h5 cxd3 17.Qxd3 b4 18.h6 bxa3 19.bxa3 g6 20.Reb1 Qc7 21.Ng4 Ba6 22.Qe3 Bc5 23.Nf6+ Kh8 24.Qc3 Qa7 25.Qd2

25. Be3 might have ended in a quick draw.


25...Nxf6 26.exf6 Rfe8 27.Re1 Kg8 28.Be3 d4 29.Bf4 Rac8 30.Ne5 Nxe5 31.Bxe5 Red8 32.Reb1 d3 33.cxd3 Rxd3 34.Qe1 Qd7 35.Kh2 Qd8 36.Rd1 Bf8 37.Bf1 Rxd1 38.Rxd1 Qb6 39.Bxa6 Qxa6 40.Qe3 Qa5 41.Kg1 Rd8 42.Rxd8

I think this was a wrong decision. Keeping the rooks on board generally increases drawing chances.Even after Black wins the a3 pawn, the ending may not be winnable.

42... Qxd8 43.Bb2 Qd1+ 44.Kg2 Qd5+ 45.Kg1 Qa2 46.Qc1 Qb3 47.g4 e5 48.g5 e4 49.Qd2 Qd3 50.Qc1 Qe2 51.Bd4 Qg4+

After this move, White did not reply, and I claimed the game after he exceeded the time limit. Black will soon win the a3 pawn. The rest is not routine, but... I was lucky this time.

0-1

Here is the crosstable: http://www.iccf-webchess.com/EventCrossTable.aspx?id=22830. Šivic, Jernej is leading the tournament with 9.5 points and has already become an ICCFGM.

MT Sustarsic: Draw against SIM Novak, Jože of Slovenia


Draw against SIM Novak, Jože of Slovenia: http://www.iccf-webchess.com/MakeAMove.aspx?id=297386. He is 58 yrs old, and a mechanical engineer. The game:

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Nf3 b6 5.Qc2 Bb7 6.a3 Bxc3+ 7.Qxc3 O-O 8.e3 d5 9.Be2 Ne4 10.Qc2 dxc4 (Novelty?)

ChessOK Opening Tree gives
 10. ... Nd7 and  A)  11. O-O Rc8 12. b3 f5 13. Bb2 Rf6 14. c5 c6  etc 0-1, Tikovsky Armin - Farsakh Christoph, Germany, 1996
 B) 11. b4 dxc4 12. Bxc4 c5 13. O-O cxb4 14. axb4 Ng5 15. Nxg5 Qxg5 16. e4 Qg6 etc 1-0, Hage Poul - Kiprov Alexander, Munich (Germany), 1936

Hereabouts Black gets a slight pull, but he is not able to increase it further.


18...Qb8 19.Nd4 Rd8 20.Qe2 Rcc8 21.Rfc1 Ne5 22.f4 Ng6 23.Rxc8 Rxc8 24.Rd1 f6 25.h4 Bc4 26.Qg4 Nf8 27.e4 b5 28.Kh2 Qb7 29.Re1 Qf7 30.h5

Now White offered a draw, which was declined.

And here White once again offered a draw, which was also declined.


49...Rb8 50.Rf2 Qc7 51.Qg6 Qd7 52.Qe4 Kh8 53.a4 Rd8 54.a5 Qc7 55.Bd4 Qe7 56.Bb6 Rg8 57.Bc5 Qg5 58.Qf4 Qh4+ 59.Kg2 Qd8 60.Qd4 Qxd4 61.Bxd4 Rd8 62.Bb6 Ra8 63.Bd4 Kh7 64.Rf7 Rd8 65.Bf2 Rd2 66.Ra7 Nxe5 67.Kg3 Nd3 68.Bc5 Nxc5 69.bxc5 Rc2 70.Rxa6 Rxc5 71.Rxe6 b4

It was now Black's turn to offer the draw which was accepted.

1/2 - 1/2

With this win, I achieved my first ICCFGM norm.

MT Sustarsic: Draw against GM Strautinš, Vilnis of Latvia

Draw against GM Strautinš, Vilnis of Latvia: http://www.iccf-webchess.com/MakeAMove.aspx?id=297334. He is 73 yrs old, and a professional musician. The game:

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nge2
The Kramer variation
5...O-O 6.Ng3 e5 7.d5 a5
More popular is 8. Be2 and 8.h4
8.Bd3 Na6 9.O-O Nc5 10.Bc2 Bd7 11.Bg5 N
Novelty? The Kings Indian is an opening that engines don't understand. In the initial stages they show a clear advantage for White, but after a dozen moves it becomes negligible. So I thought of provoking Black to try and take the initiative. In general, Kings ndian players like active play, and during that course they may weaken their Kingside critically..
( 11.a4 h5 12.Bg5 Qe8 13.Qd2 Nh7 14.Be3 Qe7 15.Nb5 Bxb5 16.cxb5 Bf6 17.Ra3 Bg5 18.Bxg5 Qxg5 19.Qe1 Kh8 20.Ne2 b6 1/2-1/2(47) Abbasov, Farid (2519) - Fierro Baquero, Martha L (2341) / XXIV Open (8), Cappelle la Grande FRA 2008 )

Now White has achieved his plan, but he does not find a way to make use of weakened kingside.
21.Be3 Be5 22. Nge2 g5 23.Qd2 g4 24.Rf2 gxh3
But now, who is attacking?
25.Rg1 Ng7 26.gxh3 Bxh3 27.Bg5 f6 28.Bh4 Bg4 29.Qh6 Kf7 30.Rgf1
And now, the tables are turned.
30...Nd7 31.c5 Rh8 32.Qe3 dxc5 33.Ba4 Ra6 34.d6 Rxd6 35.Nd5

With this exchange sac, Black simplifies to a draw.

I was lucky to win this game when my opponent exceeded the time limit on the fortieth move, in a position where perhaps White had a microscopic advantage. She was close to losing on time at the previous time control also, but managed to play the thirtieth move with just a few hours to spare.

25.Nf3 Rc2 26.e3 Rxb2 27.Ra8 b4 28.Kg2 g6 29.Ne5 Rd2 30.Rb8 f5 31.h4 Rd1 32.Nf3 Rc1 33.Nd4 Kf7 34.Rb7+ Kg8 35.Rb8 Kf7
This move was accompanied by a draw offer, which was declined.
