Ludek Pachman gives a different move order for the first 7 moves in his book <The middle-game in chess> translated by John Littlewood copyright 1982 published by Routledge & Kegan Paul Ltd. He gives: 1 e4 e6 2 d4 d5 3 Nc3 Nf6 4 Bg5 dxe4 5 Nx4 Be7 6 Bxf6 Bxf6 7 Nf3 Nd7. I do know who is right. |

 | | agb2002: White has a bishop and a knight for the bishop pair and a pawn. The open h-file suggests 19.Rh8+ Bxh8 20.Rxh8+:
A) 20... Kxh8 21.Qh1+
A.1) 21... Nh7 22.Nf6 Qxf6 (22... Kg7 23.Qh6+ Kh8 24.Qxh7#) 23.gxf6 A.1.a) 23... Bxd3 24.Qh6 Rxc2+ 25.Kd1 Rg8 26.Ng5 and mate soon. A.1.b) 23... Kg8 24.Bxf5
A.1.b.i) 24... gxf5 25.Qh6 Nxf6 26.Qxf6 + - [Q+N vs 2r+2p]. A.1.b.ii) 24... Rc7 25.Qh6 Nxf6 26.Bxg6 + - [Q+B vs 2r+p] (26... fxg6 27.Qxg6+ Kf8 28.Qxf6+ Rf7 29.Qd6+ Kg7 30.Nxe5 Rxf2 31.Qxd4, etc.). A.1.c) 23... Rg8 24.Ng5 wins decisive material.
A.2) 21... Kg7 22.Qh6+ Kg8 23.Nf6+ Qxf6 24.gxf6 Ne6 25.Ng5 and mate soon. A.3) 21... Kg8 22.Nf6+ Qxf6 (22... Kg7 23.Qh6#) 23.gxf6 A.3.a) 23... Bxd3 24.Qh6 followed by Ng5 wins.
A.3.b) 23... Ne6 24.Bxf5 gxf5 25.Ng5 wins.
A.3.c) 23... Nd(h)7 24.Bxf5 gxf5 25.Qh6 as above. B) 20... Kg7 21.Qh1
B.1) 21... f6 22.gxf6+ Qxf6 (22... Kf7 23.Nfg5#) 23.Nxf6 Kxf6 (23... Bxd3 24.Nxe8+) 24.Bxf5 wins decisive material. B.2) 21... Qxg5+ 22.Nfxg5 wins decisive material. |

| Jul-09-20 | | Brenin: On best play, 21 ... Kg8 22 Nf6+ Qxf6 23 gxf6 Rc6 24 Bxf5 Rxf6 (if 24 ... gxf5 25 Qh6 wins) 25 Be4, White ends up with Q+B+N+4P against 2R+N+6P. It looks better for White, but Black's two central pawns could be a long-term danger. |

| Jul-09-20 | | goodevans: I'm not so keen on this puzzle. The main reason is that there is only one candidate for the solution. Indeed all of white's moves are pretty obvious and there are only a few alternatives for black that need to be explored. Not particularly good for a Thursday. On the other hand you have to go pretty deep to verify that the obvious solution does indeed yield an advantage (see <Brenin>'s post). That would explain why the computer annotations to black's 18th and white's 19th moves are so badly wrong. So, an obvious solution that needs some grunt work to check it's right. Not ideal. |

|
| Jul-09-20 | | belgradegambit: Theme is obvious making an easier than usual Thursday. I thought black would give up the queen to stop mate. |

| Jul-09-20 | | Eduardo Leon: The first few moves are forced:
<19.♖h8+ ♗xh8 20.♖xh8+ ♔xh8 21.♕h1+> Now one possibility is
<21... ♘h7 22.♘f6+ ♕xf6 23.exf6 ♔g8 24.♗xf5> Black cannot take the bishop with 24...gxf5, because then white plays 25.♕g2+ and mate will immediately follow. Hence white's material surplus is more than enough to win. The other possibility is
<21...♔g8 22.♘f6+ ♕xf6 23.gxf6 ♗xd3> The computer suggests 23...♖c6, but then 24.♗xf5, and black cannot retake for the same reason as in the first line. <24.♕h6! ♖xc2+ 25.♔d1 ♘e6 26.♘g5!> Black's counterattack is too slow. If his e8 rook were already in c8, then he would be the one giving mate: 26...♖c1+ 27.♔d2 ♖8c2+ 28.♔xd3 ♘c5#. Alas, it was not meant to be. |
|
| Jul-09-20 | | Eduardo Leon: Apologies. In the first line, 22.♘f6 does not give check. |
|
| Jul-09-20 | | thegoodanarchist: I should have gotten this one, but didn't. dangit! |
|
| Jul-09-20 | | greed and death: This seems easy for a Thursday, no?
White just throws everything at the weak h-file and either forces mate or gets a huge material edge. |
|
| Jul-09-20 | | sophiephilo: Yes, easy for a Thursday. |

| Jul-09-20 | | MostlyWatch: no good. bridge out |
