| Jul-23-21 | | Brenin: 22 .. Qh4, threatening 23 ... Qxh2 mate, is going to be hard for White to answer, e.g. 23 Qxa8+ Kg7 24 Qg8+ Kh6 25 Qf8+ Kh5, or 23 h3 Ng3 mate. His best bet seems to be 23 Qxa8+ Kg7 24 Qb8, protecting h2, but allowing 24 ... Be5 25 Qxe5 Nxe5, when Black's swarm of Ns and Q around the White K should still be enough to win. |
|
| Jul-23-21 | | raymondhow: Thought I had solved it after winning the White Queen, but then instead of continuing the attack I did the pawn grab 26... Nxd3. Guess I only get half credit. |
|
| Jul-23-21 | | Walter Glattke: A) 22.-Nf2+ 23.Kg1 Nh3+ 24.Kh1 =
B) 22.-Ng3+ 23.hxg3 Qh4+ 24.gxh4 / 23.-Qg5 24.Qxa8+
C) 22.-Qh4 23.Qxa8+ Kg7 24.Qg8+ Kh6 25.Qf8+ Bg7 26.Qb8 Be5 27.Qf8+ Kh5 28.Rxf5+ gxf5 29.Bf7+ unclear
D) 22.-Nxh2 23.cxd4 (Kxh2 Qh4#) Nxf1 24.Rxf1 = |
|
| Jul-23-21 | | Refused: Only question is whether Qh4 works or not.
22...Qh4!! 23.Qxa8+ Kg7 so far so good. The problem for white is, that 24.h3 doesn't solve anything because of Ng3# a)24.Qb7+ Kh6 and white has run out of checks.
b) 24.Qb8 Be5 25.Qxe5 Nxe5 26.Kg1 (the King on h1 is just intolerable) Ne3 and a Knight is landing on g4 next, depending on where the Rook goes. If 27.Rf2 (probably relatively best) it's gonna be N3G4 if the rook leaves the f-file it's gonna be N5g4 |
|
| Jul-23-21 | | agb2002: Black has both knights for a rook and three pawns. White threatens cxd4.
Black can attack the white king with four pieces, starting with 22... Qh4: A) 23.Qxa8+ Kg7
A.1) 24.Qg8+ Kh6
A.1.a) 25.Qf8+ Bg7 26.Qb8 Be5
A.1.a.i) 27.Qf8+ Ng7 28.h3 Qg3 wins (29.hxg4 Qh2#). A.1.a.ii) 27.Qxe5 Nxe5 looks winning. For example, 28.Rfd1 (due to Ng3+ and Nxd3) 28... Ng4 29.h3 Nf2+ 30.Kg1 Nxd1. A.1.b) 25.Qb8 Be5 as above.
A.2) 24.Qb7+ Kh6 25.Qc7 Be5 as above.
B) 23.Qc7 Be5 is even worse for White.
C) 23.h3 Ng3#. |

 | | al wazir: My move was 22. Nxh2.
23. cxd4 (23. Kxh2 Qh4#) Ng3+ 24. Kg1 (24. Kxh2 Qh4+ 25. Kg1 Ne2#) Qxd4+ 25. Rf2 Ne2+ 26. Kxh2 Qh4#. To be sure, white has other moves, but I think black wins in all lines. For example, 23. Qxa8 Qxa8 24. Kxh2 Qb8+ 25. Kh1 Ng3+ 26. Kh2 Nxf1+. |
|
| Jul-23-21 | | Brenin: At the end, 29 Rxf3 loses to 29 ... Qxh2+ 30 Kf1 Qh1+ 31 Ke2 Qg2+ (better than 31 ... Qxa1 32 d4 Qxb2+ 33 Kd3) 32 Ke1 Qxf3, and the attack continues. |
|
| Jul-23-21 | | Cheapo by the Dozen: It's easy to get to the point where Black has won the queen and achieved rough material equality with an ongoing attack. That's good enough to justify the ... Qh4 line. Happily, it turns out that that attack does indeed quickly come home. |
|
| Jul-23-21 | | Walter Glattke: Please note, in my line C) white forces -Kh5 to play Rxf5 with check , and Be5 Qf8+ Bg7 Qb8 is perpetual, what happens after Ng7!? I did not test line C to the end, after that Bf7+ - how will Black win then? Agb Shows it: Ng7 h3 Qg3 is the end, so one must play 25.Qxe5 and lose (29.Rxf3 Qxh2+ 30.Kf1 Qh1+ 31.Ke2 Qg2+ 32.Kd1 Qxf3+ -++
After 22.-Nxh2 White could play 23.Rxf5 or 23.Qxa8 Qxa8 24.Kxh2 but I found black win in both ways. |

| Jul-23-21 | | Brenin: Another good reason for resigning after 28 ... Nf3+ is 29 Kg2 Qxh2+ 30 Kxf3 (30 Kf1 Qxf2#) Qf2+ 31 Kxg4 Qf5+ 32 Kh4 Qh5#. White can avoid mate by 31 Ke4, but his position is hopeless after 31 ... Qxb2. His only remote hope seems be 29 Kf1. |

It follows a different line and doesn't go as deep. |

| Jul-23-21 | | raymondhow: <vindicate lab varmint> ? So what kind of code is Chris speaking anyway? |
|
| Jul-23-21 | | njchess: 22. ... ♕h4 practically leaps off the board as the move to be played. But it is the subtle 24. ... ♗e5 that is more difficult to see. The remaining knight moves are a product of a mating web. |

 | | Jimfromprovidence: I first went with 22...Rb8 because I thought that the queen had to be driven away.
click for larger viewThis allows white to gain a tempo with 23 Qf4. Black now plays 23...Qh4, which is followed by 24 Qh3 Nf2+ 25 Rxf2 Qxh3 26 gxh3 Bxf2. 
click for larger viewBlack gets a piece for 3 pawns. Droidfish says black is ahead by a piece. Now I have to figure out why that is. |
