1. e4 c5 2. Bc4 Nc6 3. Nf3 g6 4. Nc3 Bg7 5. d3 e6 6. Be3 b6 7. O-O Nge7 8. d4 d5
9. exd5 {I decided to do this so that the e-file would be clear.} 9... exd5 10.
Bb5 O-O 11. dxc5 {Bad move! Now black can pawn-fork white's pawn and bishop.}
11... d4 12. Bxc6 Nxc6 13. Nxd4 Bxd4 14. Qf3 {White moves his queen into a
position where it can not only protect his bishop but also threaten black's
knight.} 14... Bxe3 15. Qxe3 Bf5 16. Rad1 Qf6 17. Rd6 {Aha! A rook fork between
the queen and the knight.} 17... Qe5 {Here, white probably should have first
killed the undefended knight with his rook, making up his loss, and then let the
black queen kill his queen. I don't know why I didn't do that; I probably did
not notice it.} 18. Qf3 Nd4 19. Qd5 Qxd5 20. Nxd5 bxc5 {By allowing black to
kill white's c-pawn, white has ruined black's queenside pawn structure, which
has to face with white's firm pawns, which have not been broken apart.} 21. Ne7+
Kg7 22. Nxf5+ Nxf5 23. Rd5 Rab8 24. Rb1 {When white moves his rook there, he is
guaranteeing the b-pawn safe passage to queening after making past black's
pawns.} 24... c4 25. g4 Nh4 {I did not notice that from there the knight could
easily check my king.} 26. Ra5 c3 27. b4 {Aha! Black's mistake. Now white can
advance his pawns for the most part without worry, while black's c- pawn is
stuck. I do have to adimit however, that that black pawn made me worried.} 27...
Nf3+ 28. Kg2 Nd4 {That worry escalates as black's knight can now kill white's
c-pawn and make way for his.} 29. a3 {White does that so as to protect his
b-pawn from being taken for free when black's knight kills white's c-pawn.}
29... Nxc2 30. Rc1 Nd4 {That surprised me a little. I thought my foe would move
his rook behind his c-pawn and let me kill his knight. Then, he would continue
pressuring me until I had to let his c-pawn become queen.} 31. Rxc3 Rfc8 32.
Rxc8 Rxc8 33. Rxa7 {Now white has almost complete control over the queenside.}
33... Rc3 34. a4 Ne2 {Black, now thinking that he can do nothing to stop his
foe's advancing pawns, resorts to pressuring white's king. Notice here that
black can make a two-move checkmate.} 35. f3 {White, seeing the mate, moves his
pawn as to avoid it.} 35... Nf4+ 36. Kg3 g5 {With that move, black not only
protects his knight but also prevents the king from moving onto the h-file.} 37.
b5 Rc2 {Oops! White does not see that. Now the king is in stalemate.} 38. h3
Rg2# {And now checkmate.} 0-1
