This was the fourth over the board tournament in which I competed. It is also the last time I competed in OTB competition. (When I had the money, I never really had the time; now that I have the time I don't have the money!! As the French say "C'est la vive.")

1. e4 c5 2. Nf3 d6 3. d4 Nf6 4. Nc3 cxd4 5. Nxd4 a6 6. Be2 e5 7. Nb3 Nc6 8. Bg5 Be7 9. Qd2 O-O 10. O-O-O h6 11. Bxf6 Bxf6 12. Qxd6 Qb6	Having lost a pawn already, I really did not want to exchange Queens at this point.
	1 comment chessknave (1560) on 13-Sep-07: I would have liked for white to have played 0-0, and also to have moved the knights toward the kingside of the board where black would be castling, to use for attack and to be out of the way of the queenside majority. White could have then pressed the pawn majority roller against the minority, this option is not available now because of the choices made. For black the text move makes sense to avoid an exchange when down a point and to attack f2, it looks like the best move.


13. Kb1	An oversight that permits me to regain my pawn; f3 was better.



13... Qxf2 14. Bf3 Rd8 15. Qc5	He seems intent on exchanging Queens.
	1 comment chessknave (1560) on 13-Sep-07: Looks like the best possible move because 15.Qc7 locks the queen out of the action, 15.Qb4 offers little mobility either, the file is now out of play per the rook, a counter attack by 15.Rh1-f1 Rxd6 16.Rxf2 Rxd1 17.Bxd1 clears the board of material without offering either player much and still results in a queen exchange.


15... Rxd1+ 16. Rxd1 Qh4 17. h3 Qg3 18. Nd5 Bg5 19. Qd6 Bxh3 20. Qc7	20. gxh3 is answered by 20. -----, Qxf3.



20... Rb8 21. Na5	I believe that 21. Nc5, Bxg2; 22. Bxg2, Qxg2 23. Nxb7 offers White more.
	2 comments ruachessnut2 (1200) on 12-Sep-07: Yes knights should move toward the center chessknave (1560) on 13-Sep-07: Thoughts of conquest: (21. Nc5 Bxg2 22. Bxg2 Qxg2 23. Nxb7 Nd4 24. Qxb8+ Kh7 25. c3 (25. Rc1 Bxc1 26. Kxc1 Qxc2#) 25... Qc2+ 26. Ka1 Qxd1#)


21... Rc8 22. Qb6 Nxa5 23. Qxa5 Bxg2 24. Bxg2 Qxg2 25. Nc3 Qf3	Threatening to win a piece.



26. Rd3 Qf4 27. a3 h5 28. Qd5 Rd8 29. Ne2	29. Qxd8 ch, Bxd8; 30. Rxd8 ch, Kh7 and I believe I have an endgame advantage.
	2 comments ruachessnut2 (1200) on 12-Sep-07: The passed g h pawns vs. knight will queen. Try it. Having a queen to chase the knight makes the promotion easier. chessknave (1560) on 14-Sep-07: A fun thought: (27... Qc1+ 28. Ka2 Qxc2 29. Rd5 Bc1 30. Rd8+ Kh7 31. Rxc8 (31. Qb6 Rxd8 32. Qxd8 Qxb2#) 31... Qxb2#)


29... Qf1+	White resigned.
	1 comment chessknave (1560) on 14-Sep-07: Because: (30. Rd1 Qxd1+ 31. Qxd1 Rxd1+) and black wins. Congradulations - nicely played!
