| Helloween: Excellent play by Leko to demonstrate the draw. In the final position, we have an elementary K+Q vs K+Bishop's pawn on the seventh ending, which is drawn for the 1 reason that White's King is too far away from the action to be able to jump in with 1 move. If he were, for instance, at d4, White would win easily. |

| Helloween: After 52...e5, can White win with 53.Rxa3 e4 54.Ra5!, when 54...e3 is met by 55.Rd5+? |

| Jack21221: It is only a draw with c and f pawns though, which is good to know. It is a draw because if the queen captures the pawn here, it is a stalemate. |

| stef21: this is the only drawing line, other lines loose, like 53.. Kxc3 54. Rh5!
or 53.. h2 54. Ra5 Kxc3 55. Rh5!! |

| patzer2: I had thought Leko played too conservatively by forcing the queen exchange with 28...Qe5, but according to Fritz 8 it is the best move as it minimizes White's advantage(+0.97 @ 16/47 depth & 741kN/s). Playing the tempting 28...R8f6?! would have been a mistake. Fritz 8 analyzes a winning white advantage after 28...R8f6 29. Re2! Rxh2+ 30. Rxh2 Rh6 31. Qxh6 Bxh6 32. Kg4 Be3 33. Nc2 Qb6 34. Rdh1 e5 (+1.47). |

| sangfroid: Could some one so me the draw? I just don't see it. Can't white continue to check the black king with his queen, until it comes closer and closer towards the king, threatening to fork the pawn and king if the king dosen't move to the c1 square, and since black can't promote the pawn while it's on the c1 square move the his king closer to the pawn, until its able to capture the pawn then deliver mate? |

| BeautyInChess: Sangfroid white can't capture the c pawn as long as black's king is on h1. This would be a stalemate. So to cause a draw black should move his king from a1 to b1 no matter where the white queen checks him. Of course if black gets checked on the 1st rank then black should queen the pawn to block the check and thus causing a draw with k+q vs. k+q. Any way you slice it white cannot win the pawn and thus cannot win the game. This is only true of pawns on the c or f files on the seventh rank as Jack21221 mentions. |

| patzer2: <Helloweeen> Fritz 8 analysis indicates your recommendation 53. Rxa3! is a winning move, as is 53. g5! or 53. Kg7! Apparently 53. Rxe5? is a not so obvious mistake, which thows away the win and gives black a draw. Fritz 8 @ 20/54 depth & 840kN/s analyzes:
53. Rxa3 e4 54. Kg7 (+6.13)
53. g5 Kxc3 54. Rxa3+ Kb2 55. Re3 c3 56. Rxe5 c2 57. Rb5+ Kc1 58. Rc5 Rh1 59. Kg7 Kd2 60. Rxc2+ Kxc2 (+5.84) 53. Kg7 a2 54. Ra3 e4 55. h8Q Rxh8 56. Kxh8 e3 57. Rxa2 Ke4 58. Re2 Kf4 59. Rxe3 Kxg4 60. Re4+ (+5.59) |

| Eggman: <Helloween: "... (in the final position) if (White's King) were, for instance, at d4, White would win easily" Really? I don't quite see it. |
|
| Nov-16-03 |
| fatbaldguy: I agree with Eggman's last post. I don't see a win for white - easily or otherwise... - since the black king can always retreat to a1, and the minute the queen captures on c2, it's stalemate.
In this game black did a good job of being aware of the drawing possibility that can come only if you have the seventh-rank pawn on the c or f column. |

| Eggman: If White's King is on d4 in the final position, then one try would be 61.Qg1+ Kb2 62.Qg2 Kb1 63.Qe4 Kb2 64.Qe2 Kb1?? (64...Ka1! draws) 65.Kc3! c1=Q+ 66.Kb3! winning. I see no way to get this kind of winning idea in by force, however. |
|
| Nov-16-03 |
| Helloween: Sorry, I meant if White's King were on b4. There is a particular winning zone in this kind of position and if the King of the side with the extra pawn is within it then he wins. If the King were at b4, Kb3 forces mate. |

| Dick Brain: If Black hadn't played 53...Rxh7! he would have lost identically as in the national championship game in the movie "Searching for Bobby Fischer": 53...a2? 54 Ra5 Kxc3 55 Rh5! with an x-ray attack winning the black Queen-to-be on a1. |

| rndapology: isn't a draw also the result of a rook's pawn on 7th rank with king in support? the king can hide behind the pawn and then white must move the queen off the column(either b or g) to prevent stalemate... after which the defending king moves out again. Since the pawn is on the edge of the board, it cannot be pinned to the defending king by a diagonal with the queen, so the king with the queen never has time to approach the pawn because black is perpetually threatening to promote. |

| apple head: its a draw, King always runs to a8 and if Queen takes pawn stalemate |
|

| aw1988: KQ vs KP when the pawn is a bishop pawn and the king is far enough away (in this case, yes) is a draw. Same with rook pawns. However, a center or a knight pawn loses. |

| chessgames.com: A user wrote to us asking: <Why doesn't this game appear in the Endgame Explorer results for Q vs. P?> The answer is, because the queens and pawns did not remain on the board long enough (3 half-moves) to be considered a QvP ending. This requirement of 3 half-moves prevents the Ending Explorer from miscategorizing endings during the exchange of pieces or pawns. |

| aw1988: In the game, could black have won by Kxc3 as opposed to Rxh7? |
|
| Apr-02-05 |
| aw1988: Ah, no, Rh5! |
|
| Sep-05-06 |
| HoopDreams: It is a draw with c, f, a, h pawns* |
|
| Jun-15-08 |
| ravel5184: <Jack21221> It is a draw with Rook-Pawns too (if the Black King is close enough) because after the King goes to the corner and the White Queen is on b3 (g3), it is stalemate if the White King moves. |
|

| WhiteRook48: 53...Rxh7 is trivial |
