| Nov-16-15 | | Marmot PFL: An unfortunate loss by Short in an important match. After a poor opening white fights back bravely, just to see his king tragically check mated only a few moves later. |
|
| Nov-16-15 | | luzhin: I wouldn't exactly describe it as tragic, or even unfortunate: Black is better from the early middle-game and gradually increases his advantage. But 45...Bd4! is neat and most precise. |

 | | MissScarlett: Talking of tragic, I can't let this tournament pass without remarking on Short's weight problem. He looks terrible. |
|
| Nov-16-15 | | TheFocus: Maybe he should change his name to Short Round. |
|

 | | Domdaniel: Short's decision to imprison his Rook on b7 is hard to understand -- unless maybe he anticipated later giving up the Exchange in return for a passed pawn. |

 | | al wazir: Got it.
The tricky part was recognizing the the immediate 45...Rd6 doesn't work because black has to give up his ♕ and then is an exchange down, or else is mated: 46. Qxd6 cxd6 47. Rxf7+ Kg8 48. Rg8+ Kf8 49. Ne6+ Ke8 50. Re7#. |
|
| Oct-31-19 | | Stale.Mate: L’chaim! This is the first time I’ve ever seen all the moves with my first glance at the board. |
|
| Oct-31-19 | | drollere: there are several ways to win from the puzzle position. <the immediate 45...Rd6 doesn't work>
45. .. Rd6+, 46. Qxd6 cxd6, 47. Rxf7+ Kh6, 48. R- Bd4+ |

 | | An Englishman: Good Evening: Nice series of Knight moves from 17-21 for Black. Clever means of exploiting White's passive play. |
|
| Oct-31-19 | | patzer2: Picked 45...Bd4! -+ and 45...Rd6+ -+ as my candidate moves for today's Thursday puzzle. I went with 45...Bd4! because it calculates to a quick mate after 46. Qxd4 Rd6+ -+ (M10, Stockfish 10 @ 35 ply). I didn't go with 45...Rd6+, even though Black has a winning material advantage after 45...Rd6+ 46. Kxf7 Bd4! 47. Qxd6 cxd6 -+ (-8.17 @ 32 ply, Stockfish 10). Given the pleasant task of deciding between a winning material advantage and a quick mate, 45...Bd4! was my obvious choice. P.S.: Black's game took a turn for the worse with 19. Rc4?! Nc3 29. Qd2 Nba2 ∓ (-1.15 @ 32 ply, Stockfish 10). Instead, 19. Ne6! fxe6 20. Bxe4 Na2 21. Rc4 Nc3 Qd2 Nxe4 23. Rxe4 c6 24. Rxe6 Rxe6 25. dxe6 Qe7 26. Qb4 = (-0.07 @ 34 ply, Stockfish 10) would've held the game level. |
|
| Oct-31-19 | | patzer2: After 45...Rd6+ 46. Qxd6, Black wins easy with the in-between move 46...Bd4+! -+ (-8.93 @ 33 ply, Stockfish 10). |
|
| Oct-31-19 | | agb2002: Black has a bishop and a pawn for a knight.
The white rook is trapped, which suggests Qc8 but there must be something better taking into account the position of the white king: Rd6+ or Bd4. In the case of 45... Rd6+:
A) 46.Kxf7 Bd4 (46... Qd7+ 47.Qe7 -47.Kf8 Rf6+ 48.Qxf6 Bc5+ 49.Qe7 Qxe7#- 47... Rf6+ 48.Kxf6 Qf5# fails miserably because 48.Kxf6 checks the black king and 48... Qf5# is illegal) A.1) 47.Qxd4 Qd7+ 48.Kf8 Qd8+ 49.Kf7 Rd7+ 50.Ke6 Qe7#. A.2) 47.Qe7 Rd7 wins decisive material.
A.3) 47.Qe4 Qd7+ 48.Qe7 (48.Kf8 Rf6#) 48... Rf6#. A.4) 47.Rxc7 Bxd4 48.Kf8+ just loses too much material. B) 46.Ke7 Qd7+ 47.Kf8 Qc8+
B.1) 48.Kxf7 Rd7+ 49.Ke6 (49.Kf6 Qd8+ as in the line) 49... Qe8+ 50.Kf6 Qd8+ and mate next. B.2) 48.Qe8 Rd8 wins decisive material
C) 46.Qxd6 Qf5+ 47.Ke7 cxd6 48.Rxb6 looks advantageous for Black but complex. D) 46.Ne6 Bd4 wins decisive material.
-----
In the case of 45... Bd4 46.Qxd4 Rd6+ transposes to A.1 above (47.Ne6 Qxd4). -----
I'd play 45... Bd4. |

|
| Oct-31-19 | | saturn2: I went with 45...Qc8 winning an exchange. The counterattack 46. Qe7 does not work because of 46...Rd7. |
|
| Oct-31-19 | | saturn2: Is 45...Bd4 46. Qxd4 Rd6+ <47. Ke5> Qf5# too trivial that nobody mentions it? |
|
| Oct-31-19 | | malt: Went for 45...Rd6+ at first,
46.K:f7 Qd7+ 47.Qe7
Looked at 45...Kg8
Settled for 45...Bd4! 46.Q:d4 Rd6+ 47.K:f7 Qf5+ 48.Ke8 Kg8 |

|
| Oct-31-19 | | ClassZPlaya: I chose 45. ... Rd7 which also wins, but is not the best move. |
|
| Oct-31-19 | | faulty: I fail to find the win if white responds 47. Ne6 |
|
| Oct-31-19 | | Cheapo by the Dozen: I had a little trouble seeing Move 49 and beyond, but there's a good chance I've have played this line anyway with Spielmannesque faith. |
|
| Oct-31-19 | | patzer2: <faulty> If 47. Ne6 Qxd4+ -+, and Black wins the Queen because the pinned Knight can't recapture. |
|
| Oct-31-19 | | King.Arthur.Brazil: Well, this time I did everything right! |
|
| Oct-31-19 | | nummerzwei: Straightforward combination. Weird to see GMs play it out to mate. |
