| Nov-15-18 | | ChessHigherCat: Pretty easy for a Thursday unless I'm missing something (which is often the case): 25. Rxh7+ Kxh7 26. Qxg6+ Kh8 27. f5 Rg8 28. Qh5+ Kg7 29. Qxg4+ Kh7 30. Qh5+ Kg7 31. Qg6+ Kh8 32. Qh6# |

|
| Nov-15-18 | | ChessHigherCat: <qkxwsm: harder if the puzzle starts at 24.?> I thought that, too.
I missed black's best defense (27...Qe8), but even then white's clearly winning: 1) +6.58 (20 ply) 27...Qe8 28. Qxg4 Qe3+ but 29. Kh1 and black's goose is cooked like a Thanksgiving turkey. |
|
| Nov-15-18 | | wtpy: CHC, Welcome back--haven't seen any you post for awhile. I went with 27 f5 as well; Stockfish likes it better than the game continuation. |
|
| Nov-15-18 | | stacase: The first move, 25.Rxh7+ is easy enough to see - Black is forced to accept the Rook sacrifice. The rest of the way you have to deal with Black's Bishop which hasn't moved for the whole game. White could easily tie it up with perpetual check Qg6 & Qh5 - but winning is a bit more dodgy. Black's Queen is eventually overworked allowing the white Rook to join in on the fun. |

Did not see 27.h3 |
|
| Nov-15-18 | | Count Wedgemore: <spazzky: 27.f5 was more direct> Yes, and now the knight is hanging. And Black cannot save it (for example, 27...Ne3 (or...Ne5) 28.Qh6#). 27.Qh5+ followed by Qg6+, and then f5 is also good and achieves the same result. |

 | | keypusher: The first two moves were pretty obvious, but then I noticed that that 27.Qh6+ doesn't quite work out...obviously figuring out how to deal with the knight on g4 was the key. 27.h3 seemed far too slow. Once I spotted 27.f5 I was sure I'd solved the puzzle. Turns out that I am stronger that Sokolov. :-) |
|
| Nov-15-18 | | saturn2: me too went with 27 f5 because after 27 h3 I thought (and am still thinking) 27.. Qe8 holds. |
|
| Nov-15-18 | | agb2002: White is one pawn down.
Black threatens gxh5, Qxd6 and Ne3.
The first maneuver that comes to mind is 25.Rxh7+ Kxh7 26.Qxg6+ Kh8 27.Qh5+ Kg7 28.f5: A) 27... Qxd6 28.Qxg4+ and mate in three.
B) 27... Ne3 28.Qg6+ Kh8 29.Qh6#.
C) 27... Bxf5 28.Qxf5 Qc8 29.d7 Qc5+ 30.Kh1 Nf2+ 31.Kg2 Qe7 (31... Rfc8 32.Qg6+ and mate next) 32.Qg6+ Kh8 33.Qh6+ Qh7 34.Ng6#. D) 27... Qd7 28.Qxg4+ and mate as in B.
E) 27... Qe8 28.Qxg4+
E.1) 28... Kh8 29.Ng6+ Kh7 (29... Kg7 30.Nxf8+ wins decisive material) 30.Nxf8+ Qxf8 31.Qg6+ Kh8 32.Re1 Bd7 33.Re4 followed by Rh4 wins. E.2) 28... Kh7 29.Kf1, with the idea Re1-Re7+, looks winning. E.3) 28... Kh6 29.Qf4+ Kg(h)7 30.Ke1 as above. |
|
| Nov-15-18 | | agb2002: 27.Qh5+ Kg7 28.f5 loses to 28... Ne5 because White doesn't have 29.Qg6+. However, 27.f5, instead of 27.Qh5+ to try to capture the knight with check, wins according to Stockfish. |

| Nov-15-18 | | gofer: A nice simple finish...
<25 Rxh7+ Kxh7> (forced) <26 Qxg6+ Kh8> (forced) <27 f5!!!>
A simple pawn move, but it is all over, black has some pointless spite checks, but the
real point is that Ng4 is lost or has to move and after that black has no defence.

28 Qh6#
27 ... Rg8
28 Qh5+ Kg7 (Ng6 Qxg6#)
29 Qxg4+ ...

30 Bxg8 mating soon
<27 ... Qe8>
<28 Qxg4 Qe3+>
<29 Kh1 Qg5>
Black has used up all its spite checks and now has to try to swap off queens. In human mode,
I would simplify into a winning end game...
<30 Ng6+ Kg7>
<31 Qxg5 fxg5>
<32 Nxf8 Kxf8>

I looked at the alternative <27 h3>, but prefered <27 f5> as did <ChessHigherCat>. But we also got the move order right too, unlike <agb2002>, because we realised that Ne5 was big problem if I played Qh5+ before f5! |

 | | Jimfromprovidence: It's also ok for white to play 27 Qh5+ first because he can transpose to the same position as 27 f5 two moves later after 27...Kg7 28 Qg6+ Kh8 29 f5.
click for larger view But it took me quite a while to see that playing f5 on either move 27 or move 29 threatens mate in 5 beginning with Qh5+. |
|

| | Jimfromprovidence: <Count Wedgemore> gets the credit for seeing 27 Qh5+ followed by 28 Qg6+. |

 | | gawain: I saw the initial moves but could not work out how to conclude the attack. Typical of my results on Thursdays. |
|
| Nov-15-18 | | Jambow: I didn't see it to conclusion but I saw the first 4 moves and think I would have then been able to bring it home. |
