| Nov-21-02 | | ughaibu: Another nice game. At first glance the only chance appears to be 24.Rfc8 immediately. |
|
| Nov-21-02 | | Cyphelium: Then I suggest 25.Ng6+. That move lacks punch with the rook on e8, but now it's different. 25.-fxg6 loses to 26.Qg7+ :
26.-Kd6 or Ke8 28.Rxe6+
26.-Kd8 27.Rd1+
Don't taking the knight and just moving the king out of the check is no pick-nick for black either.
25.-Kd8 26.Qf8+ Kd7 27.Bb5+ Qc6 28.Qe7 mate 25.-Kd7 26.Bb5+ Kd6 27.Qf4+ Kc5 anyone for black? Perhaps Kholmov's 24.-Rfe8 was meant to deal with the threat of Ng6. |
|
| Nov-21-02 | | ughaibu: Cyphelium, interesting analysis. Have you any suggestions for black at some point? |
|
| Nov-21-02 | | Cyphelium: The rook sac 19.Rxg7! looks very strong to me. It seems hard to avoid the rook sac for black after 17.-Nxe3, since black is almost forced to play 18.-Kh8 efter 18.Qxe3. So I suggest that black could wait with 17.-Kh8!? instead of the knight move. The idea is (apart from the obvious avoidance of something evil landing on h6)that if white wants to open the lines with, say, a natural 18.h3, then black plays 18.-Nxe3 and white cannot play 19.Qxe3 because of 19.-Qxc4, when the g7 sac doesn't seem to work. |

 | | perfidious: This game has Sunday writ large as a POTD. |
|
| Aug-24-17 | | zydeco: 17...exd4 looks like the principled move, although it gets wild there too. A sample variation: 18.Nxd4 Ne5 19.Bxh6 Qxc4 20.Rxg7+ Kh8 21.Qh5 Bf4+ and then probably 22.Bxf4 Kxg7 loses, but 22.Kb1 wins. Lots of alternatives and everything gets tactical. |
|
| Sep-11-21 | | Brenin: This seems rather easy for a Saturday, with an obvious 17 Rxg7, and if 17 ... Kxg7 then a straightforward follow-up 18 Rg1+ Kf6 (Kh7 19 Ng5+ hxg5 20 Qxg5 with mate to follow) 20 dxe5+ Bxe5 22 Qxh6+ Ke7 23 Re1 f6 24 Nxe5 fxe5 25 Qg7+. |

| Sep-11-21 | | JohnTal: 19 Rxg7 immediately grabbed my attention. This is a move you play without thinking while you have the supreme confidence that you will mate the king or recovery any sacrificed material while retaining a significant winning advantage. I saw the first 2 moves and figured that once Shamkovich forced the Black king into the open, Kholmov would be finished off efficiently even if one could not a 10 move winning combo. |

 | | Teyss: <Brenin: This seems rather easy for a Saturday> Not for patzers like me. Granted the first two moves are easy but then there are quite some variations and pitfalls beginning with 21.Qxh6+? instead of dxe5+: after 21...Ke7 e.g. 22.dxe5 the d6 B can move and White's attack falters. Even after 23.Re1 Black has different ways to defend (all failing): the game continuation, your ...f6 or ...Qxc4 where White must find the right path being R vs 2Ps down. Then lines multiply beyond my small brain's capacity. Beautiful nonetheless. For info after 24...Bxc4 there is a pretty mate in 4: 25.Nc6+ Kd7 26.Re7+ Kc8 27.Qxf8+ Qd8 28.Qxd8# |
|
| Sep-11-21 | | Tomate: The interesting point is the move order, when to play dxe5.
Indeed here the best is the most forcing line.
19.Rxg7 (19.dxe5 Bc5 looks unclear) 19...Kxg7
20.Rg1+ (20.dxe5 Qxc4 is unclear) 20...Kf6
(21.Kh7 Ng5+ 22.Kh8 Nxf7+ or 22.hxg5 Qxg5 are winning)
21.dxe5+ Bxe5 (21...Ke7 22.exd6+ .Kxd6 23.Qe5+ Kc6 24.Qd5+ Kb6 25.Qb5#) 22.Qxh6+ Ke7 (22..Kf5 23.Bd3#)
23.Re1. Here I looked only to 23..Qxc4 because otherwise
2P+the exposition of the black king is clearly enough for the exchange. Then 24.Nxe4 Qe6 25.Qh4+ and white will skewer a rook. Similarly 20.dxe5 Qxc4 is unclear. So better is |

 | | Jimfromprovidence: <Teyss> <Even after 23.Re1 Black has different ways to defend (all failing)......... or ...Qxc4 where White must find the right path being R vs 2Ps down.> There is a really neat solution to the puzzle after 23..Qxc4 24 Nxe5 Qe6 25 Qh4+ Ke8. 
click for larger viewThe knight seems pinned; it can't move forward because of ...Qxe1#. So how about 26 f4!, protecting the knight as well as the rook.

| Sep-11-21 | | agb2002: White has a bishop and a knight for the bishop pair. Black threatens Qxc4.
The first idea that comes to mind is 19.Rxg7 Kxg7 20.Rg1+: A) 20... Kf6 21.dxe5+ (21.Qxh6+ Ke7 22.Qh4+ Ke8 and White's attack looks weaker) 21... Bxe5 (21... Ke7 22.exd6+ Kxd6 23.Rd1+ Kc6 24.Ne5+ wins) 22.Qxh6+ Ke7 23.Re1 (more effective now than eventually in the first subline) A.1) 23... Qxc4 24.Nxe5, with the double threat Nxc4 and Ng6+ looks very good for White. A.2) 23... Be6 (blocks the e-file and connects rooks) 24.Nxe5, with two pawns and attack for the exchange, looks good for White. A.3) 23... Qxd6 (threatens Qxh6) 24.Rxe5+ Be6 25.Qh4+ looks very good for White (25... Kd7 26.Re4 threatens Rd4 and Ne5+). B) 20... Kh7 21.Ng5+
B.1) 21... Kh8 22.Nxf7+ Qxf7 (22... Rxf7 23.Qxh6+ Rh7 24.Rg8#) 23.Bxf7 Rxf7 24.Qxh6+ Rh7 25.Qf6+ Rg7 26.Qxg7#. B.2) 21... hxg5 22.Qxg5 and mate in two.
B.3) 21... Kg8 22.Ne6+ Kh7 23.Rg7+ Kh8 24.Qxh6#. B.4) 21... Kg7 22.Ne4+ Kh7 23.Nf6+ Kh8 24.Qxh6#. |

| Sep-11-21 | | agb2002: <Jim> I overlooked 24... Qe6 in my line A.1 but four alternatives to 26.f4 are 26.f3, 26.Rd1, 26.Nd3 and 26.Nf3. I don't know which is strongest. I'd have to run DroidFish to check this. |
|
| Sep-11-21 | | agb2002: After a few minutes, DroidFish evaluates 26.f4 as strongest at +5 and the rest at +4. |

| Sep-11-21 | | NBZ: This is the first game I have seen with comments from as far back as 2002. |

| Sep-11-21 | | stacase: Yeah, the Rook sacrifice is an obvious puzzle move, but I sure didn't see that it was a winning proposition. |
