 | | al wazir: I got 39. Rdxe7 without difficulty, but after 39...Rxe7 40. Rxg6+ I thought black had to play 40...Rg7+. There follows 41. Bxg7, and if 41...Rxg7 then 42. Rxg7+ Kxg7 43. Ne6+ and it's all over. |

| Jun-08-19 | | Cheapo by the Dozen: I got only part of this.
39 Rdxe7 forces recapture. It's obvious that after 39 ... Bxe7 40 Rxg6+ that White has a strong attack, but I didn't calculate the quick forced mate correctly. In the game line of
39 ... Rxe7
40 Rg6+ (Black interposes)
I anticipated a grand exchange on g7, started by White's rook, followed by a knight fork at e6. I didn't see that Black could reduce the harm -- but still lose fatal amounts of material -- by refusing to recapture and playing ... Kf8 instead. |

 | | scormus: First moves easy enough to spot but Judit would have seen the need to follow up correctly after 39 ... Rxe7 and the ensuing attempted defense. 43 Bh6+ might have been ... tempting but the quiet manoeuver 43 Bd4 and 44 Bc5 was the quiet killer |

| Jun-08-19 | | groog: I don't often solve Sat's, this was pretty straight forward. Beautiful game. |

| Jun-08-19 | | Gabriel King: Beautiful, well done and very hard to find. I didn't get this one. I saw most of the moves, but I couldn't imagine that after 41. Bxg7, black couldn't answer Rxg7 because of RxR, KxR and then white follows with Ne6+! and wins. A complex position with lots of ideas, most of them don't work though. For instance, I thought about 39. Rf6 for quite a long time, trying to slowly bring the rook to h8 through movements like Rf7, Rh7 and then Rh8. Obviously it doesn't work (black can easily exchange pieces and dominate the seventh row), but that was a beautiful idea (making chess looks something like Ludo, that simple board game for kids). |

| Jun-08-19 | | agb2002: White is one pawn down.
Black threatens Rxd7.
The black king does not have a legal move and the knight protects g6. This leads to consider 39.Rdxe7: A) 39... Rxe7 40.Rxg6+
A.1) 40... Bg7 41.Bxg7
A.1.a) 41... Rxg7 42.Rxg7+ ends up a knight ahead (42... Kxg7 43.Ne6+ and 44.Nxd8). A.1.b) 41... Re2+ 42.Kc3 looks winning, for example, 42... Rd5 43.Bf6+ Kf8 44.Rh6 with the threat Rh8#. A.2) 40... Rg7 41.Bxg7 as above.
B) 39... Bxe7 40.Rxg6+ Kf8 41.Bg7+ Kg8 42.Bh6+ Kh8 43.Nf7+ Kh7 44.Rg7#. |

| Jun-08-19 | | mel gibson: I didn't see it.
The idea was to get rid of the black Knight in order to take the pawn in front of the black King
then the white Knight could exact vengeance.

 | | Knightf7mate: I did not see that bishop check coming, nor did I see right away that after K-e8 R-g8 is mate. Perhaps Karpov thought his king could climb up and stand on the rook at d7 to escape. The key move here is the threat of the knight fork of the two black rooks. I did not see that, so I didn't find the compelling advantage for white. Every sequence I looked at was an even exchange of material. It shows the depth of Polgar to find the tactical sequence for the win that positionally ought to be there. |

| Jun-08-19 | | thegoodanarchist: 39.? White to move.
To me, the summary of this combination is that White can fork the Black rook on d8 and king on g7, by moving his knight to the forkarooni square e6. There are only 2 small problems. The Black king is not on g7! And, there is already a White piece on the forkarooni square, e6. Does she let these tiny details spoil her day? No! She merely sacs the exchange to remove the defender of g6. Then the forkarooni is on!
I don't know about you, but I hate it when my opponent finds a forkarooni. |
|
| Jun-08-19 | | seneca16: Actually a rather simple combination arising in a rapids game. I didn't see it because I didn't sufficiently examine the first move. Once you get that it's pretty straightforward. I was looking at Ne4 threatening to go to f6, either as the first or second move, but that goes nowhere. |
|
| Jun-08-19 | | TheaN: Once you realize that recapturing on e7 with the bishop (removing defenders at the king) leads to mate (as has been described a few times), 39.Rdxe7 is obvious. The more critical line goes <39.Rdxe7 Rxe7 40.Rxg6+ Bg7 (Rg7 41.Bxg7 Bxg7 42.Rxg7+!) 41.Bxg7!> where retaking allows White to clear the board with a knight to boot after 42.Rxg7+! Essentially Black misses defenders on g7. As such, Black attempts <41....Re2+ 42.Kc3 +-> but has no real way to properly defend the king and is already two pieces for rook down. |

 | | Breunor: Losing move was 34 Bh6. Best was Bh2:
1) +0.52 (23 ply) 34...Bh2 35.Rg2 Nd5 36.Nd4 Bf4 37.Nxc6 Re2+ 38.Kb1 Nxc3+ 39.bxc3 Rbe8 40.Nd4 Re1 41.Rxg6+ Kf7 42.Rg1 Rxg1 43.Rxg1 Re4 44.Kc2 Be5 45.Rg5 h4 46.f3 Re1 47.Kd2 Bf4+ 48.Kxe1 Bxg5 49.Kd1 Kf6 50.Ke2 Bf4 51.Kf2 Bd2 2) +2.17 (22 ply) 34...Bh6 35.Rd7 Bf8 36.Be5 Rb5 37.Bd6 Rd5 38.Nc7 Rxd6 39.Rxd6 Rb8 40.Ne6 Nd5 41.Rxg6+ Kf7 42.Nxf8 Kxf8 43.Rd7 Nxb4+ 44.Kc3 Nd5+ 45.Kd4 Rxb2 46.Rxc6 Ne7 47.Rcc7 Rd2+ 48.Kc3 Rxd7 49.Rxd7 Kf7 50.Rd6 Nf5 51.Rxa6 I think the key to Bh2 is that after 35 Rg2 Black has Nd5 threatening the powerful knight on e6 and threatening to exchange the powerful bishop on c3; one of white's powerful pieces will get traded off. |

| Jun-08-19 | | patzer2: For today's Saturday puzzle solution, I correctly guessed the initial move 39. Rdxe7! If Black tries to "win the exchange" with 39...Bxe7, White has a mate-in-five with 39... Bxe7 40.Rxg6+ Kf8 41.Bg7+ Kg8 42.Bh6+ Kh8 43.Nf7+ Kh7 44.Rg7#. If 41...Rxg7, White wins decisive material with a Knight fork after 41...Rxg7 42. Rxg7+ Kxg7 43. Ne6+ Kf6 44. Nxd8 +-. P.S.: So where did Black go wrong? The decisive mistake was 34...Bh6?, allowing 35. Rd7! +- (+4.47 @ 32 ply, Stockfish 10). Instead, Black's only chance of avoiding the loss was 34...Bh2 35. Rg2 Nd5 Bf4 ⩲ (+0.47 @ 32 ply, Stockfish 10). Earlier, instead of 26...g6? potentially allowing 27. Nxe5+ fxe5 28. Rge1 ± (+0.97 @ 32 ply, Stockfish 10), Black could have kept it level with 28...fxg5 29. Bxg5 Bd6 = (+0.09 @ 32 ply, Stockfish 10). |

 | | OhioChessFan: Even for Rapids, this is a pretty massive beatdown of Karpov. |
|
| Jun-08-19 | | 1stboard: Could this / should this be Judit Polgar's immortal ?? One of the best finishing combinations I have ever seen |
|
| Jun-08-19 | | oceline2: The KEY of this position is Ne6 which forks the d8 Rook & g7 (the square of the exchanges). This protects g7 and Bxg7 can be done after Rdxe7 Rxe7
Rxg6+ Bg7 |
