| Jan-28-20 | | agb2002: White has a bishop for two pawns.
Black threatens Rxe3.
The square f6 is defenseless. Therefore, 37.Nxd5: A) 37... Rxe2 38.Nf6+ Kh8 (38... Kg7 39.Nxe8+) 39.Nxe8 wins decisive material. B) 37... Re5 38.Qxc4 + - [B].
C) 37... Re6 38.Nf4 Re5 39.Qd6, with a bishop for a pawn, looks winning (39... Rg8 40.Bxc4). |

| Jan-28-20 | | Skewbrow: White has a bishop for two pawns. The immediate trouble is that the white minor pieces are sitting there like shish-kebab on the skewer of doubled black rooks. That problem is easily resolved with 37. Nxd5. True, the bishop at e2 is only defended once, but the knight can retaliate: 37..Nxe2 38.Nf6+ forking the rook e8. If black chooses a defensive 37th move, a quiet 38.Qxc4 leaves white a full piece up with no compensation for black. Trying to pin the knight with 37..Re5 still gets the response 38.Nf6+. |

| Jan-28-20 | | saturn2: White can keep his material plus by
37. Nxd5 Rxe2 (otherwise Bxc4) 38. Nf6+
exchange for a pawn and black has many weaknesses |
|
| Jan-28-20 | | Anjeneyar: Relatively best for Black is
38.....Kg7. 39. Nxe8+.Rxe8 when Black is an exchange down+Bad is
38.....Kh8. 39. Rxe2! (better than Nxe8.) and White is a Rook up! B cannot play 39....Rxe2 due to 40. Qf8# Harry |
|
| Jan-28-20 | | Walter Glattke: Better possibly 38.-Kh8 39.Rxe2 Rxe2 40.Qf8# or 38.-Kg7 39.Rd7+ Qxd7 40.Nxd7 Re1+ 41.Kg2 Nd8 42.Qd4+ |
|
| Jan-28-20 | | saturn2: <Anjeneyar: Relatively best for Black is 38.....Kg7. 39. Nxe8+> There is
39. Rxe2 Rxe2 40. Rd7 getting the black queen. |
|
| Jan-28-20 | | Damenlaeuferbauer: After long pondering, my 20 years young Norwegian friend Aryan, who is promising much for the future, finally found 37.Nxd5!,Rxe2 38.Nxf6+,Kh8 (38.-,Kg7 39.Rd7+ winning the queen for a rook) 39.Rxe2,Rxe2 40.Qf8#. |
|
| Jan-28-20 | | Lambda: Rd7 is also effective against Kh8, forking the queen and mate on h7. On Qb1+ Rf1 keeps it under threat. |
|
| Jan-28-20 | | GlennOliver: 37. Nf5 is also a clear win, albeit not as quickly as the textual move. |
|
| Jan-28-20 | | TheaN: Noticing that White's a piece up is probably the hardest part of this puzzle. I actually decided to play 38.Rxe2 first, and SF agrees with me that this doesn't change too much. The game line 38.Nf6+ is with check, yet Black has the option to attack the knight. This makes no difference as she has no time to take it after 37....Kg7 38.Rxe2, now if 38....Kxf6 39.Rxe8 +-: the drawback of going up two rooks for the bishop is that queens are still on the board, yet Black is helpless. 38....Rxe2 follows the alternative, winning the queen with 39.Rd7+. Playing 38.Rxe2 immediately actually limits Black's options as there's no proper way to defend f6. Defending the rook, for example 38....Qb8? allows 39.Rxe8 Qxe8 40.Nf6+ +-, and after 38....Rxe2 39.Nf6+ Kg7 (Kh8 40.Qf8#) 40.Rd7+ does exactly the same as the game line. As sidenote, strangely, the analysis after 38.Nf6+ Kg7 39.Rxe2 Kxf6 gives me <1) mate-in-58 (26 ply) 40.Rxe8 >. Okay. Right. |

|
| Jan-28-20 | | swclark25: I also went with 37.Nxd5
I assumed Black would respond with 37...Rxe2, but Black would have been better with 37...Rf7 and kept White's lead at +5.56 versus +11.55 with 37...Rxe2 |

 | | ajk68: This was so straightforward I thought I was missing the correct line. I decided I would play Nxd5, as I saw nothing better. |
|
| Jan-28-20 | | Momentum Man: I missed this because I didn’t consider how powerful Nf6+ would be. Both ...Kh8 and Kg7 by black get blown off the board. I ‘would have noticed had I been patient |
