CHESS either — White is deprived of counterplay and won’t be able to fend off eventual intrusion on the b-file. 16. Be3 16. Rd1? Be2 17. Rd2 Bxf3 — White is deprived of his only useful move. 16...Rfb8 17. Re1 Bc4 Black has been playing very well up to this point, but here he starts going astray. This move threatens nothing and disrupts the coordination of the black pieces. 17...Rb3 merits attention; 18. cxb3 Rxb3 19. Qxb3 Qxb3 is hopeless, but 19. Qc2 allows the strong 19...Bd3. 18. Nd2 Ba2 19. Qd3 Rb2 19...Qa5 20. Rxa2 Rb1+ 21. Nxb1 Qxe1+ 22. Qd1 Rxb1+ would have been a worthy ending of this game, but White is not forced to take on a2 and could play 20. Kd1 instead. 20. Qc3 R2b5 21. Qd3 Ra5?? Black finally collapses under the pressure and blunders very badly. 21...Rb2 22. Qc3 Qb5 and Black’s advantage is indisputable. 22. c4 Bxa3+ 23. Qxa3 Rxa3 24. cxd5 cxd5 25. Kd1 And White converted his advantage. 1-0 White: Jay Bonin Black: Denys Shmelov [E18] Queen’s Indian Defense 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Bb7 5. Bg2 Be7 6. O-O O-O 7. Nc3 Na6 Black tries to avoid the drawish lines which arise after 7...Ne4 8. Nxe4. Ironically, he blunders almost right away and finds himself fighting for a draw the rest of the game. 8. d5 Bb4 9. Ne5 Bxc3 10. bxc3 exd5? 10...Nc5 defends the bishop on b7 and ensures a reasonable game. 16 WWW.MASSCHESS.ORG HORIZONS 11. Bg5 Qe7 12. Ng4 Qe6 13. Nxf6+ gxf6 14. cxd5 cuuuuuuuuC {rdwdw4kd} {0b0pdpdp} {n0wdq0wd} {dwdPdwGw} {wdwdwdwd} {dw)wdw)w} {PdwdP)B)} {$wdQdRIw} vllllllllV Now would be a good time to take stock of my position. My pawn structure is ruined, my pieces are poorly coordinated, my king is exposed, and my opponent has two bishops and a strong presence in the center. I am playing against an experienced international master, the game is played in a team competition, and the outcome of the match will likely hinge on the outcome of the game. Time to switch to defensive mode... 14...Qf5 15. Bh6 Happy with his position, W h i t e goes on a streak of mediocre moves. My rook wants to get to e8 anyway, whereas the white bishop would stand better on f4. 15... Rfe8 16. e4 Qg6 17. Be3 17. Bf4 still looks like a better choice. 17...Nc5 Now White has to give up his dark squared bishop, since 18. f3 could be answered by 18...f5. Black is still very much worse, but in a bad position like this every bit helps. 18. Bxc5 bxc5 19. Qa4 f5 Jumping on a chance to get rid of my doubled pawns, but... 20. Rab1 White finds a very strong move, forcing Black to part with material. 20...Ba6 21. exf5 To add to his woes, Black is now down a pawn. 21...Qd6 22. Qg4+ Happy with his position, White again goes on a streak of mediocre moves. The Black king would be safer on h8, so there was no need to force him there. 22...Kh8 23. c4 This pawn becomes a weakness in need of constant defense. 23...Re5 24. Rfe1 Rg8 25. Qh4 f6 26. Bf1 Bc8 26...Rxf5? 27. f4 strands a rook; instead Black just makes a waiting move. 27. f4 White has been playing without a clear plan for some time now; however, only now does he make a real mistake. In one move White weakens his king and sidelines his queen, giving Black chances for some counterplay. 27...Re7 28. Kf2 Now White goes astray, underestimating the dangers of having a weak king. After an accurate 28. Qh5 White will be able to bring his queen back, with good chances to convert his advantage. 28...Rge8 29. Qh6 Looks as if the best Black can do is trade rooks, but... 29... c6! ...makes White regret playing in such a daring manner. Now taking on c6 is obviously out of the question, and taking on e7 would most likely lead to perpetual check. 30. Bg2 If 30. dxc6?? Qd4+ and Black wins. 30. Rxe7 Qxe7 31. Rd1 Qe3+ 32. Kg2 Qe4+ 33. Kg1 Qe3+= (but not 33...Qxf5?? because of 34. Bd3+-). 30...Ba6 31. Bf1? Better is 31. Red1 Bxc4 32. dxc6= 31...cxd5 31...Rxe1!
