| Feb-25-18 | | wtpy: Got it through 26 e7 but did not see Re1 in response to Kb7, in fact I spent some time analysing the black king going to e8. And Re1 is a crucial move in the line played in the game.I suspect over the board I would have seen it. |
|
| Feb-25-18 | | Cheapo by the Dozen: What's hard about this? Grab the two knights for the rook, and hope you can bring the win home from there. |
|
| Feb-25-18 | | sudoplatov: I missed this one completely. I came up with 23.gxf5 fxg5 24.e6 Be8 25.Rxd8+ Kxd8 26.Rd1+ Kc8 27.Ne7+ Kb2 28.Nxg8 which fails to ...Bh5. |
|
| Feb-25-18 | | AlicesKnight: It had to be something like this but I would not have found it. Another one for the Knight promotion collections. |
|
| Feb-25-18 | | agb2002: White has a bishop and a knight for the bishop pair. Black threatens fxg5.
The position of Black's lsb and knight suggest gxf5, Rxd7 and e6. In the case of 23.Rxd7:
A) 23... Kxd7 24.gxf5 fxg5 25.e6+
A.1) 25... Kc8 26.e7 and White has some material advantage. A.2) 25... Kd6 26.b4 creates mating threats. For example, 26... c5 (26... Bf6 27.Rd1+ Bd4 28.Rxd4#) 27.Nfe5 cxb4 28.cxb4 c5 29.Rd1+ Kc7 30.Rd7+ Kc8 (30... Kb8 31.Nc6+ Kc8 32.Nge7+ Bxe7 33.Nxe7+ and 34.Nxg8) 31.e7 cxb4 32.exd8=Q+ Rxd8 33.Ne7+ Kb8 34.Nc6#. A.3) 25... Ke8 26.e7 Bxe7 27.Re1 is similar to A.1. B) 23... fxg5
B.1) 24.gxf5 Kxd7 transposes to A.
B.2) 24.Rfd1 Nh6 25.e6 Bf6 26.Nfe5 Kb7 and White looks better. -----
In the case of 23.e6 Bxe6 24.gxf5 Bxf5 25.Ngh4 Bh3 26.Be3 Bxf1 White doesn't look better. -----
In the case of 23.gxf5 Bxf5 (23... fxg5 24.e6 Be8 25.e7 Bxg6 26.exd8=Q+ and fxg6 wins decisive material) 24.Ngh4 Bh3 25.Be3 Bxf1 26.Kxf1 unclear. -----
I'd probably play 23.Rxd7. |

| Feb-25-18 | | patzer2: Didn't see the possibility of trapping the Bishop in today's Sunday (23. ?) puzzle with 23. Rxd7! Kxd7 24. gxf5 fxg5 25. e6+ Ke8 26. e7 Re8 27. exd8(Q)+ +- (+2.08 @ 34 ply, Stockfish 8). Instead, I went with 23. gxf5 which levels out to an even game after 23. gxf5 Bxf5 24. Ngh4 Bg4 25. Rxd8+ Rxd8 26. exf6 gxf6 27. Bxf6 Rf8 28. Be7 Rxf3 29. Nxf3 Bxf3 30. Re1 = (-0.08 @ 35 ply, Stockfish 8). P.S.: According to the computer, Black's decisive mistake was 22...Bd8 which allows 23. Rxd7! +- (+2.08 @ 34 ply, Stockfish 8). Although it isn't pleasant for Black, the better alternative appears to be 22...Be8 23. gxf5 Bxg6 24. fxg6 fxg5 25. Nd4 Re8 26. Nxc6 Kb7 27. Nd4 Bc5 ± (+1.31 @ 38 ply, Stockfish 8). Earlier, Stockfish 8 indicates Black can improve over 17...Be7 18. Nf4 ⩲ (+0.31 @ 33 ply) and secure full equality with 17...Ba3 18. Rd2 c5 = (0.00 @ 34 ply). |

| Feb-25-18 | | drollere: the sac at Rxd7, Kxd7 was not hard to find.
i admired the way that the linked passed pawn was used to force the king back to 25. .. c8, then the threatened fork at e7 was used to prevent the bishop capture (with material edge) and gain the tempo to allow Re1 (promoting to N seemed a little fancy, but whatever). at 23. Rxd7, would movsesian have seen that 29. Re7 was vindicated by 32. c4, or that the f5 passed pawn would cost dearly to stop? |

 | | Breunor: I looked at the first few moves, but didn't see trapping the black bishop. My instincts said this has to be the line since we are endowed with 'white to play and win' but even with that knowledge I couldn't see it through. |

 | | Jimfromprovidence: I did not realize that 28 exd8 = N was critical to the success of the combination. Here is the text after 29 Re7, where white has two black pawns en prise.
click for larger viewHowever if 28 exd8 = Q, black has 28...Rxe1+, forcing 29 Nxe1, below, with an even game after 29...Rxd8. 
click for larger view At 29 ply, Stockfish indicates that 28 exd8 = N is two pawns better than 28 exd8 = Q. |

| Feb-25-18 | | njchess: I agree. The critical move was 28. exd8=♘+. I thought 23. ♖xd7 ♔xd7 24. gxf5 fxg5 25. e6+ ♔c8 26. e7 was pretty obvious. I wasn't sure what Black would do for his 26th move, but I thought White should play 27. ♖e1 forcing ♖e8. I spent a lot of time on the promotion. After some time, I realized that White promoting to a queen would allow Black a check, and a tempo. Therefore, the knight promotion forcing check was critical. The rest is tactics. |

| Feb-25-18 | | frdes: C4 is helpful |
|
| Feb-25-18 | | stst: Since the center is tough to crack, observe that the Black R is lonely on a-file. Try the side line:
23.Ra1 RxR (if K moves to protect, result pretty much the same)
24.RxR Kb7 (for afraid the back rank B gone, the remaining R vulnerble)
25.Bf4 (leave the B for later use) Ne7
26.NxN BxN
27.exf Bxe6
28.Bxc7 (exchange for more) KxB
29.Ra7+ Kd8
30.g5 Be7
31.Ne5 Bc8
32.Nxc6+ Ke8
33.RxB+ Kf8
34.Rc7 Be6
35.Ne7 Rh8
36.Ng6+ fork Kg8
37.NxR KxN
and White got both material, position, and tempo,... rest easyBut, see the game goes this line.... |

 | | Richard Taylor: I went for Rxd7 I was still a bit skeptical about it though as I thought Black could get a R to a2 and another to d2 and slow the force of White's push... But it seemed the best plan to go for the 2 Ns vs the R and a passed pawn... So de facto I solved it without seeing all the complexities... |
|
Feb-26-18
| | Richard Taylor: The underpromotion is clever. I won a game by "Queening" a N once as it was also a check. Great play by White against a formidable opponent... |

| | Richard Taylor: <Jimfromprovidence: I did not realize that 28 exd8 = N was critical to the success of the combination. Here is the text after 29 Re7, where white has two black pawns en prise.> Yes it is I suspected it is better without Stockfish. My error was to look for an assault on the Black King forgetting the power of that passed pawn. But I only looked for a few minutes... I recall when i started here spending hours analysing and trying to solve the "insane" puzzle. I solved quite a few, but not many, it takes so much time... Good practice though if you are a young player trying to improve etc... |
