| Apr-14-18 | | ChessHigherCat: The knight looks irredeemably lost (boohoo) because if 20. Qe5 Bf6 so how about 20. Bxg7 threatening Qxh6 and Qxh8#. If 20...Kxg7 21 Nxe6+ wins the queen.
If 20. Bxg7 Rxc5 it's important to avoid the hybris move of 21. Qxh6 because of Rh5! but it suffices to trade rooks and then play Qxh6, I think. If 20. Bxg7 Bg5 then 21. Nxe6 (not check this time) and if Rxc1 21. Rxc1 and black's bishop on g5 is pinned. Let's see if that was pure delirium.. |
|
| Apr-14-18 | | ChessHigherCat: <GSM> Did you really see all that and think it was simple? I didn't consider 22...f6, for which omission I flagellate I myself with a wet noodle, but I'm pretty sure I would have found 23.Bxf8 Bxf8 24.Qg6+ Bg7 25. Qe8+ Bf8 26. Qxe6+, which is winning but taint mate. |

 | | Gregor Samsa Mendel: <CHC>--I saw most of it, I think. I usually don't get Saturday puzzles beyond the first move or two. |
|
| Apr-14-18 | | patzer2: Found the first four moves of today's Saturday puzzle ( 20. ?), but got greedy on the fifth move and went for the simple pawn grab 24. Qxf6 ± to +- (+2.09 @ 23 ply, Stockfish 9). Instead, I should have gone for the much stronger Queen fork combination with 24. Qg6+! +- (+8.45 @ 20 ply, Stockfish 9) which picks off the unprotected Bishop in two more moves (e.g. 24...Bg7 25. Qe8+ Kh7 26. Qxe6 +-). P.S.: Instead of 17...Nb4 allowing 18. Na4 = (+0.14 @ 30 ply, Stockfish 9), Black could have secured the advantage by centralizing the Knight and blocking the long diagonal with 17...Nd4 ⩱ to ∓ (-0.52 @ 31 ply, Stockfish 8). |

| Apr-14-18 | | diagonalley: i go along with <Gregor Samsa Mendel> ... particularly given that the first move is easy to pick out... good puzzle though |

 | | agb2002: Black threatens Rxc5.
Both queens are defenseless and the black castle has vulnerabilities. These details suggest 20.Bxg7: A) 20... Kxg7 21.Nxe6+ fxe6 22.Qxb5 wins.
B) 20... Rxc5 21.Rxc5 (21.Qxh6 Rh5)
B.1) 21... Qxc5 22.Qxh6 f6 (22... f5 23.Bxf8 Bxf8 24.Qxe6+ + - [R+2P vs n]) 23.Be4 B.1.a) 23... f5 24.Bxf8 Bxf8 25.Qxe6+ and 26.Qxf5 + - [R+3P vs n]. B.1.b) 23... Rd8 24.B(Q)h7+ Kf7 25.Q(B)g6#.
B.1.c) 23... Bd6 24.Bxf8 wins decisive material (24... Bxf8 25.Qh7#). B.1.d) 23... Bf5 24.Bxf5 Qxf5 25.Bxf8 Bxf8 26.Qd2 +/ - [R+2P vs b+n]. B.2) 21... Bxc5 22.Qxh6 f6 23.Be4 and Black does not have Bf5 as in B.1.d. C) 20... Bxc5 21.Qxh6 as in B.2.
D) 20... Bg5 21.Nxe6
D.1) 21... Bxc1 22.Qxb5 wins.
D.2) 21... Rxc1 22.Rxc1 Bxc1 23.Qxb5 wins.
D.3) 21... fxe6 22.Rxc8 Rxc8 23.Bxh6 with the double threat Qg6+, Qg7# and Qxg5. |
|
| Apr-14-18 | | stacase: Yes, the first move is easy to pick out, and after running through this thing a few times the rest seems pretty much forced. You do need to see what 20...Rxc5 does and trade Rooks. After 24.Qg6+ Black resigns, his Bishop is toast and White has a clear advantage. |

| Apr-14-18 | | patzer2: After the Stockfish 8 recommended improvement 17...Nd4 (diagram below),
click for larger viewit appears Black is dropping a pawn after 18. Na4 (diagram below). 
click for larger viewHowever, Black has the clever response 18...Qa6! (diagram below). 
click for larger viewNow if Black goes for the greedy pawn grab 19. Nxc5? (diagram below), 
click for larger viewBlack has the strong double attack 19...Qe2! (Queen fork), which attacks the unprotected Queen and Bishop and forces the win of the exchange with a Knight fork after 20. Qxe2 Nxe2+ 21. Kh1 Nxc1 ∓ to -+ (-1.70 @ 35 ply, Stockfish 8). |
|
| Apr-14-18 | | Marmot PFL: 20 Bxg7 naturally since if Kxg7 21 Nxe6+ and knowing that after 22 Qxh6 white has two pawns + attack for the piece. With Qh8 threatened black has no time to save Rf8, although Bxf8 may not be white's only option as Be4 also looks very strong. |

 | | wtpy: Since Bg7 is forced,because otherwise white drops a piece, I have to agree with GSM, the puzzle is easy for a Saturday. If it was Thursday, I would have no complaints, other than the obvious, "What the f!#$ happened to my Saturday and why is it Thursday again?" |

 | | Jimfromprovidence: Here's an interesting (likely unforced) line if black takes the knight with the bishop. 20...Bxc5 21. Qxh6 f6 22. Bxf8 Bxf8 23. Qg6+ Bg7

24. Rxc8+ Bxc8 25. Rd1 Bd7 26. Bf1!
click for larger view 26 Bf1 is the key move of the combination, allowing for 27 Bc4+. 26...Qf5 27. Bc4+ Kh8 28. Qf7 Kh7 29. Rd4

 | | Breunor: Jimfromprovidence,
I tried your variation in Stockfish.
On 20 Bxc5 21 Q x h6 f6 Stockfish recommends 22 Be4: +10.14 (20 ply) 22.Be4 f5 23.Bc3 Bxf2+ 24.Rxf2 Rxc3 25.Qxe6+ Rf7 26.Rxc3 Qb6 27.Rc8+ Kg7 28.Qe8 Qxf2+ 29.Kxf2 fxe4+ 30.Kg2 Kf6 31.Qxe4 Nc6 32.Qf4+ Ke6 33.Re8+ Re7 34.Rxe7+ Nxe7 35.Qc7 Kf7 36.Qxb7 |

 | | fm avari viraf: Well, I won't say a difficult one since prima facie 19.Bxg7 would seal Black's fate! |
|
| Apr-14-18 | | landshark: I don't know what's going on, but after a successful Sunday last week (I blew Wednesday this week and skipped the last two for business reasons), I found all of today's moves quite quickly. I didn't think sharks were capable of evolving but these last few puzzles are making me wonder... |

Feb-23-21
 | | An Englishman: Good Evening: According to legend (i.e., don't take my word for this), Bellon played 1.b3 so often during the early 1970s that at one tournament the people manning the demonstration boards would already have the pawn on b3 when he arrived at the hall, before the game even began. Rather amusing when you think about the games when he actually had the *Black* pieces. |

| Feb-23-21 | | dhotts: Donald Byrne sure knows how to get blown apart, sort of like what Fischer did to him in the 1956 US championship when Fischer won the brilliancy prize. Robert Byrne was not much better, loss to Fischer in 21 moves in 1963 US championship. The Byrne brothers may have been GMs in their day, but their play seems to languish in the middle games allowing great players to easily dissect them like a dead carcass. |

Especially re Robert. Many GMs would kill for his overall score against Fischer. Donald never got the GM title, I think. |
