| Sep-26-06 | | Autoreparaturwerkbau: 35.Qh6! leaves the poor rook alone to be taken+check by black queen, but Kasparov had other plans... Well seen. |
|
| Apr-26-15 | | RKnight: Huebner correctly resigned. 39...Qe8 (if 39...Qxd1 40.Nh8+ Ke6 41.Rh6+) 41.Ne5+ and black's queen falls. |
|
| Mar-30-17 | | Dave12: 35.Qh6. this 'take my Rook and check me, but you are lost' move, requires a precise calculation. Reminds of the beautiful 44.Kg1!! in this amazing gmae D Khismatullin vs Eljanov, 2015 |

 | | agb2002: White is one pawn down.
Black threatens Qxd2.
After 35.Qh6 Qxe1+ (35... Kf8 36.Nxg6+ is surely winning) 36.Kh2 White's attack seems to win: 36... Kf8 (36... Qxe5+ 37.dxe5 and White looks much better) 37.Nxg6+ Kg8 (37... Kf7 38.Ne5+ Kf8 39.Rg3 looks winning) 38.Qh8+ Kf7 39.Qxd8 Kxg6 (39... Qxd1 40.Ne5+ Ke6 41.Rh6+ and mate in two) 40.Bh5+ Kh6(7) 41.Bf7#. |
|
| May-19-19 | | eaglewing: 36. Kh2 Qxe5+ 37. de Re8 might give Black a bit of hope and at least require White to work for a win. |

 | | AylerKupp: <dorsnikov> I'm with you. I saw 35.Qh6 almost immediately and considered it a winning move but I thought that it couldn't be played because White's Re1 was en prise. Then, almost immediately again I said to myself "So what?". Black still has no defense. But after 36.Qh6 Qe1+ 36.Kh2 Kf8 instead of Kasparov's 37.Nxg6+ I chose the obvious 37.Qh8+ which according to Stockfish 10 also wins but with somewhat greater difficulty. Hubner could have put up slightly greater resistance with 37...Qxe5+ but Stockfish indicates that this leads to a mate in 27 for White after 37.Nxg6+ while 37.Qh8+ leads to "only" a mate in 28 for White: Stockfish 10, d=44:
1. [+M27]: 37.Nxg6+ Kf7 38.Ne5+ Qxe5+ 39.dxe5 Rdg8 40.Bh5+ Rg6 [looks suicidal but the alternatives are much worse: (a) 40...Kf8 41.Ra3 Ba4 (horizon effect at work; delay the inevitable as long as possible) 42.Rxa4 b5 43.Ra8+ Ke7 44.Qd6# and (b) 40...Ke7 41.Qd6#] 41.Bxg6+ Rxg6 42.Qh7+ Ke6 [Black could quite justifiably resign here but the alternatives are again much worse; 43...Rg7 least to mate in 8 and 43...Kf8 leads to mate in 4. 42...Ke6 at least leads to more horizon effect-induced delay of the inevitable] 43.Qxg6+ Kxe5 44.Rh5 Bd3 45.Qxc6 Kd4 46.Qd6 Kc4 47.Rh4+ f4 48.Rh5 Be4 49.Qe6 Kd3 50.Rxd5+ Bxd5 51.Qxd5+ Kc3 52.Qf3+ Kb2 53.Qxf4 b5 54.Qb4+ Kc2 55.Qxb5 Kc3 56.Qc5+ Kb2 57.g4 Kb3 58.g5 Kb2 59.g6 Kb3 60.g7 Ka4 61.g8R Kb3 62.Rb8+ Ka4 63.Qa7# 2. [+M28]: 37.Qh8+ Rg8 38.Nxg6+ Kf7 39.Ne5+ Kf8 40.Qh6+ Ke7 41.Qh7+ Kd6 42.Rh6+ Nf6 43.Rxf6+ Kd5 44.Qf7+ Kxd4 45.Nf3+ [and Black could quite justifiably resign here also] 45...Kc5 46.Rxf5+ Rd5 47.Rxd5+ cxd5 48.Qc7+ [Stockfish is being quite sadistic, delaying the capture of Black's queen as long as possible. I wonder if it has an undocumented UCI parameter of SADISM=1?] 48...Bc6 49.Nxe1 Re8 50.Nd3+ Kd4 51.Qxc6 Rh8+ 52.Kg1 Kxd3 53.Qxd5+ Kc3 54.Qe5+ [then again, 51...Rh8+ did not turn out well] 54...Kb4 55.Qxh8 Kc5 56.Qe5+ Kc6 57.Ba4+ b5 58.Bxb5+ Kb6 59.Ba4 Kb7 60.Qb5+ Kc7 61.Qc6+ Kb8 62.Bd1 Ka7 63.Qc7+ Ka6 64.Be2# So I think that I should get at least partial credit for 37.Qh8+. Which would console me somewhat since I also sometimes can't get the "easy" Monday or Tuesday puzzles either. |

 | | Breunor: Well I saw Qh6 and given it was a puzzle I knew it was the right move, but I can't say I 'solved' it as I didn't have everything that black could do worked out. Besides the finale, I thought that Kasparov's knight maneuver to get it to e5 was really terrific. this was a representative game of his superior positional play then finishes off with tactics. In the 'where did black go wrong' issue:
Black is even until 25 Nd5, the computer prefers Ba6 After Nd5: 1) +0.52 (19 ply) 24.Qa3 Rc7 25.g3 Kg7 26.Qb3 Re7 27.Rxe7 Nxe7 28.Ne3 h5 29.Rd1 b5 30.Qc3 Nd5 31.Nxd5 cxd5 32.Qc5 Qd7 33.Rc1 Re8 34.Qc7 After Ba6 we have:
1) +0.10 (21 ply) 23...Ba6 24.Rbc1 Nd5 25.Qb3 Bxc4 26.Rxc4 Re8 27.Rd1 Rc7 28.Rcc1 Qd7 29.b5 Rd8 30.Rxc6 Rxc6 31.bxc6 Qxc6 32.g3 Qd7 33.Rb1 Qd6 34.Bg2 Qd7 35.Re1 Qd6 36.Qb2 Qb4 37.Qxb4 Nxb4 although in this line black plays Nd5 next move anyway and they score close to even. The losing move is 32 f5? which obviously opens up the king to attack. 1) +2.43 (24 ply) 33.Bxf5 gxf5 34.Rg3+ Rg7 35.Rxg7+ Kxg7 36.Qg5+ Kf8 37.Qxf5+ Qf6 38.Nd7+ Rxd7 39.Qxd7 Qf7 40.Qd8+ Kg7 41.Re5 Bd3 42.b5 Bxb5 43.Rg5+ Kh7 44.Rg3 Be2 45.Rh3+ Bh5 46.Qg5 Nf6 47.g4 Qe6 48.Kg2 Qe4+ 49.Kh2 Nxg4+ 50.Kg3 Nf6 51.Qxf6 Qg6+ 52.Qxg6+ Kxg6 53.Kf4 Bd1 54.Ke5 Bc2 55.f4 Instead, black is solid with
1) +0.66 (21 ply) 32...Re7 33.Rh3 Qf6 34.Rf3 Qh4 35.g3 Qh7 36.Nxf7 Rxf7 37.Be6 Rf8 38.Qg5 Kg7 39.Rxf7+ Rxf7 40.Qe5+ Rf6 41.Ra1 Qh5 42.Bxd5 Qxe5 43.dxe5 Rf5 44.Ra7+ Kf8 45.Be4 Rxe5 46.Bxg6 c5 47.bxc5 Rxc5 48.Rf7+ Kg8 49.Rb7 Bc6 Kasparov makes a 'relative' error with 33 Bd1:
1) +1.82 (23 ply) 33...f4 34.Bc2 Ba4 35.Rh3 Bxc2 36.Qxc2 Kg7 37.g4 Qf6 38.Kg2 Rh8 39.Rxh8 f3+ 40.Nxf3 Kxh8 41.Qe4 Kg7 42.b5 Qf4 43.Qxf4 Nxf4+ 44.Kg3 Nd5 45.Re6 cxb5 46.Ne5 g5 47.Rg6+ Kf8 48.Kf3 b4 49.Rd6 Nf4 50.Rxb6 Nh3 51.Rxb4 Rc3+ 52.Ke2 Rc2+ 53.Kd3 Rxf2 54.Rb7 Kg8 55.Kc4 Rf8 It looks like black needed f4 to keep the white queen out of h6, but after Rg7, its all over: 1) +4.19 (22 ply) 34.Rh3 g5 35.Bb3 Re8 36.Rh5 Rf8 37.Qe3 g4 38.g3 Ba4 39.Ba2 Qf6 40.Kg2 Rh7 41.Reh1 Rxh5 42.Rxh5 Bc2 43.Bxd5+ cxd5 44.Nd7 Be4+ 45.Kf1 Qf7 46.Rg5+ Kh7 47.Nxf8+ Qxf8 48.Rh5+ Kg6 |
|
| May-19-19 | | devere: 35.Qh6 Qxe1+ 36.Kh2 is easy to see. But the crux of the matter is that after 36...Qxe5+ 37. dxe5 Re8 38. Bb3, material is approximately equal, but Black has no way to successfully defend his position from White's attack.
