Some King and Pawn Endings

I have always had a fascination with King and Pawn endings. I think it's because they are so deceptively simple-looking, yet often contain such wonderful complexities. Following are some of these endings from my ICC library.

The first one was played on 2/19/97 vs. jk. Instead of 41...Kf5, winning easily, my 41...Kf7?? loses even though I am a Pawn up at the time.
1. d4 Nf6 2. c4 c5 3. Nf3 cxd4 4. Nxd4 e6 5. Nc3 Nc6 6. g3 Bc5 7. e3 Nxd4 8. exd4 Bb4 9. Bd2 O-O 10. Bg2 d5 11. c5 Bd7 12. O-O Bc6 13. a3 Bxc3 14. Bxc3 Rb8 15. b4 b6 16. Rb1 a5 17. Qc2 axb4 18. axb4 bxc5 19. bxc5 Bb5 20. Rfe1 Qd7 21. Bf1 Bxf1 22. Kxf1 Ne4 23. f3 Nxc3 24. Qxc3 Rfc8 25. f4 Qa4 26. Rec1 Qa6+ 27. Kf2 Rb7 28. Rxb7 Qxb7 29. c6?

This has to be wrong on principle. While the old adage is that "passed Pawns must be pushed", that does not apply here, since pushing the c-Pawn only makes it inevitable that it will be captured, becauss the Black King is closer to it than his White counterpart. On c5 it was protected, whereas it is weak on c6.

29...Qb6 30. Qc5 Qxc5 31. Rxc5 Kf8 32. Ke3 Ke7 33. f5 Kd6 34. fxe6 fxe6 35. Kf4 Rxc6 36. Rxc6+ Kxc6

The King and Pawn endgame has been reached.

37. Ke5 Kd7?

Too passive. The aggressive 37...Kb5 wins easily. After 38 Kxe5 Kc4 39 Ke5, a zugzwang position has arisen in which all Black needs to do is force White to move his King first. This can be easily done with 39...g6, creating an identical Pawn position on the g and h files, so that all Black has to do after that is mirror White's moves and he wins.

This game was played at a bullet time control (2,1), which does not lend itself to accurate endgame play. I hate bullet, but I used to play it some since it was often the only way to get a game on ICC. The same drawback exists with the 5,0 blitz time control, in that by the time the ending comes around there is likely not enough time to give it the thought it needs. I realized early on in my internet play that my favorite blitz time control is 2,10, which is 2 minutes initially, and 10 seconds for each additional move. This gives the player at least some time to think through crucial endgame positions like the one here.

38. h4 Ke7 39. g4 Kf7 40. Kd6 Kf6 41. g5+ Kf7?? (41...Kf5-+) 42. Ke5 Ke7 43. h5 g6 44. h6 Kf7 45. Kd6 e5 46. Kxe5 Ke7 47. Kxd5 Kd7 48. Ke5 Ke7 49. d5 Kd7 50. Kf6 Kd6 51. Kg7 Kxd5 52. Kxh7 Ke6 53. Kxg6 Ke7 54. Kg7 Ke6 55. h7 Kf5 56. h8=Q Kxg5 57. Qf8 Kg4 58. Qf6 Kg3 59. Qf5 Kg2 60. Kg6 Kg3 61. Kg5 Kg2 62. Qf4 Kg1 63. Qd2 Kf1
64. Kf4 Kg1 65. Kg3 Kf1 66. Qf2# {Black checkmated} 1-0
This next one was played on 5/1/98 vs. kq. Either 38 cxb5 or 40 Kg4 would have won easily. Incredibly, I find a way to lose as White.
1. e4 g6 2. d4 Bg7 3. c4 d6 4. Nc3 Nd7 5. f3 e5 6. d5 Ne7 7. Be3 b6 8. Qd2 Nc5 9. h4 Ba6 10. h5 Qd7 11. hxg6 hxg6 12. Rxh8+ Bxh8 13. O-O-O O-O-O 14. Nh3 Bg7 15. Ng5 Ng8 16. g3 Na4 17. Bh3 f5 18. exf5 gxf5 19. Nxa4 Qxa4 20. b3 Qa5 21. Ne6 Qxd2+ 22. Rxd2 Rd7 23. Nxg7 Rxg7 24. Bxf5+ Kd8 25. g4 Bc8 26. Rh2 Bxf5 27. gxf5 Ke8 28. Rh8 Kf7 29. Kc2 Rg2+ 30. Kd3 Nf6 31. Bh6 Rg8 32. Rxg8 Nxg8 33. Bg5 Nf6 34. Bxf6 Kxf6 35. Ke4 a6 36. f4 exf4 37. Kxf4 b5 38. a4 bxa4 39. bxa4 a5 40. Ke4 Kg5 41. f6 Kxf6 42. Kf4 Kg6 43. Kg4 Kf6 44. Kh5 Ke5 45. Kg5 Kd4 46. Kf5 Kxc4 47. Ke6 Kc5 48. Kd7 Kxd5 49. Kxc7 Kc5 50. Kb7 d5 {White resigns} 0-1

Vs. Cyberknight on 8/9/00, I throw away an easy draw with 42...c4??

1. d4 f5 2. e3 e6 3. Bd3 Nf6 4. Bd2 Be7 5. f4 O-O 6. Nf3 d6 7. O-O c6 8. Be1 Qe8 9. Nbd2 Qh5 10. c3 Nbd7 11. Ng5 Qxd1 12. Rxd1 Nb6 13. c4 h6 14. Ngf3 Ng4 15. Bf2 Bd7 16. h3 Nf6 17. b3 Rad8 18. e4 fxe4 19. Nxe4 Nxe4 20. Bxe4 Bf6 21. Nh2 e5 22. fxe5 dxe5 23. dxe5 Bxe5 24. Bd4 Rxf1+ 25. Nxf1 Bxd4+ 26. Rxd4 Kf7 27. Bf5 Ke7 28. Bxd7 Rxd7 29. Rxd7+ Kxd7 30. Ne3 Ke6 31. Kf2 Nd7 32. Kf3 Ne5+ 33. Ke4 Nd7 34. Kd4 c5+ 35. Ke4 b6 36. Nf5 Nf6+ 37. Kf4 Ne8 38. g4 Kf6 39. Ne3 Nc7 40. Nd5+ Nxd5+ 41. cxd5 b5 42. Ke4 c4??

Not only does this careless move throw away an easy draw, but Black may well win if White isn't careful. For example, the game could continue 42...g5 43 a3 a6 44 b4 c4 45 Kd4 Ke7 46 Kc3 Kd7 47 Kd4 Kd6 48 Ke4 c3 49 Kd3 Kxd5 50 Kxc3 Ke4 51 Kd2 Kf3 52 Kd3 Kg3 53 Ke4 Kxh3 54 Kf5 Kg3-+. To avoid giving Black the passed Pawn in this line, White must give up his own passed Pawn with 44 d6, after which the game is a dull draw.

43. bxc4 bxc4 44. Kd4 c3 45. Kxc3 Ke5 46. Kc4 Kd6 47. Kd4 g5 48. a3 a6 49. Kc4 Kd7 50. Kc5 Kc7 51. d6+ {Black resigns} 1-0

In the next, vs. sceptic on 3/1/03, Black wins the zugzwang battle but loses the war.

1. d4 d5 2. c4 e5 3. dxe5 d4 4. g3 Nc6 5. Nf3 Nge7 6. Bg2 Ng6 7. O-O Be6 8. b3 Qd7 9. Bb2 O-O-O 10. Nbd2 Ngxe5 11. Nxe5 Nxe5 12. Nf3 Nxf3+ 13. Bxf3 h5 14. Qd2 Bg4 15. Bg2 c5 16. Qa5 Kb8 17. Ba3 b6 18. Qa6 Bh3 19. Rab1 Bxg2 20. Kxg2 Qb7+ 21. Qxb7+ Kxb7 22. b4 Kc6 23. bxc5 Bxc5 24. Bxc5 bxc5 25. Rb5 Rb8 26. Rfb1 Rb6 27. a4 Rhb8 28. Kf3 a6 29. Rxb6+ Rxb6 30. Rxb6+ Kxb6 31. Ke4 Ka5 32. Kd5 Kb4 33. a5 g6 34. f4 f6 35. h3 g5 36. h4 gxh4 37. gxh4 f5 38. Ke5 Kxc4 39. Kxf5 d3 40. exd3+ Kxd3 41. Kg6 c4 42. f5 c3 43. f6 c2 44. f7 c1=Q 45. f8=Q Qg1+ 46. Kxh5 Qd1+ 47. Kg5 Qg1+ 48.

{Black resigns} 1-0

This next position really takes the cake. The position looks ridiculously simple--all the remaining Pawns are on the g-file. I innocently play 62...Kh5, and after that can only draw, even though I have an extra Pawn. Black is JT, played on 3/15/97.

In the next, vs. Colstrip on 2/19/97, I can win with 33...Kd4.

In the next, as White vs. MCapelo on 11/25/97, I throw away the win on the 33rd move, and then the draw on the 41st move.

1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. Ne2 dxe4 5. a3 Bxc3+ 6. Nxc3 Nf6 7. Bg5 h6 8. Bxf6 Qxf6 9. Nxe4 Qg6 10. Qd3 Bd7 11. O-O-O Bc6 12. f3 Nd7 13. h4 O-O-O 14. h5 Qh7 15. g4 Nf6 16. Nxf6 Qxd3 17.

I am especially proud of the next game because it was a one-minute game, a time control I am notoriously poor at. I recognize the zugzwang position, run him out of moves till he has to move his King, and then Queen a Pawn and mate him with 5.1 second left on my clock!

The next one, played as White against afr64 on 11/15/97, is not a very interesting game, but take a look at the position after 47 Kg5. White has his King on g5 and a Pawn on h4, while Black has his King on c5 and a Pawn on h5. Black's Pawn is about to fall, leaving him with King vs. King and Rook Pawn. But, in the words of the "Cool Hand Luke" warden, he doesn't have "his mind right". He should be thinking, "just get my King to f8 and I have the draw". Toward that end, 47...Kd6 is called for, reaching f8 in 2 more moves. Instead, he blunders horribly with 47...Kd5??, and now cannot recover.
