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
