Jul-31-07 | | Whitehat1963: Here's an excellent puzzle! White to move after 8...g5. |

Nov-24-18 | | abstract: It's always exciting to see French defence fails |
|
Apr-22-22 | | Brenin: There are two obvious candidates: 9 Nxe6 and 9 Nxg5. The first fails to 9 ... fxe6 10 Nxg5 Nf8, so that Qh5+ is answered with Ng6. The second leads to 9 ... Bxg5 (otherwise Black loses a P) 10 Nxe6 (forking Q and B) fxe6 11 Qh5+ Kf8 (11 ... Ke7 loses the Q to 12 Bxg5+) 12 Bxg5 Qe8 (Qc7 is only slightly better) 13 Bh6+ Kg8 (or 13 ... Ke7 14 Qg5+ Kf7 15 Qg7 mate) 14 Qxe8+ Nf8 15 Qxf8 mate. After 9 Nxg5 Black's better defence is 9 ... Ndxe5, losing some material but surviving. |
|
Apr-22-22 | | Brenin: After 9 Nxg5 Ndxe5 10 N(either)xe6 Bxe6 11 Nxe6 fxe6 12 dxe5 White is a P up with 2Bs and a much better position. However, Black has survived, which is more than can be said for the game line 9 ... Bxg5. |

Apr-22-22 | | fokers13: Spotted the game sequence but missed the Nf8 resource,move order really is important here. Easy for a friday unles someone rushes and mucks it up like i did |

Apr-22-22 | | mel gibson: I wasn't sure -
I didn't see any quick checkmate.
Stockfish 15 is only giving a 2 point advantage to White and
follows only the first ply:

Apr-22-22 | | areknames: Good puzzle and interesting opening trap. Black should probably have played 8...cxd4 9.cxd4 and only now 9...g5 as 10.Nxg5? fails to 10...Bb4+. White could instead play 10.Nh5 g4 11.Ng7+ Kf8 12.Bh6 Kg8 13.Nd2 Qb6 with an unclear position where Black's king is safer than one would think. |
|
Apr-22-22 | | agb2002: Black threatens gxf4.
Black cannot play g6 to block the e8-h5 diagonal. These details suggest 9.Nxg5: A) 9... Bxg5 10.Nxe6
A.1) 10... fxe6 11.Qh5+ Kf8 (11... Ke7 12.Bxg5+ wins decisive material) 12.Bxg5 A.1.a) 12... Qe8 13.Bh6+ Ke7 (13... Kg8 14.Qxe8+ Nf8 15.Qxf8#) 14.Qg5+ Nf6 (14... Kf7 15.Qg7#) 15.Qxf6+ wins two pawns at least. A.1.b) 12... Ne7 13.Bh6+ Kg8 14.Qg4+ Kf7 (14... Ng6 15.Qxe6#) 15.Qg7+ wins decisive material. A.1.c) 12... Qa5 13.Qh6+ Kf7 (13... Ke8 14.Qxe6+ and mate next; 13... Kg8 14.Qxe6+ and mate next) 14.Be2 Ne7 (14... Rg8 15.Qxh7+ Rg7 [15... Kf8 16.Bh6+ wins decisive material] 16.Bh5+ Kf8 17.Bh6 wins decisive material) 15.Bh5+ Ng6 16.Bxg6+ hxg6 17.Qxh8 wins decisive material. A.2) 10... Qe7 11.Nxg5 wins two pawns.
B) 9... Nf8 10.Nf3 or 10.h4 (10... Bxg5 12.hxg5 Qxg5 13.Nxe6) wins a pawn. |

 | | duddles: I suspect 8...g5 is one to regret |
|
Apr-22-22 | | AlicesKnight: Found the gameline with the better order of N captures. White ends material-up after 14 ... Nf6, and I think the Black KR is in peril after further Q and B checks. Just a "matter of technique" to win. |

Apr-22-22 | | TheaN: Indeed, the question here is which pawn first. That's <9.Nxg5 ±>. Nxe6 fails rather simply because after 9.Nxe6 fxe6 10.Nxg5 Black has too many moves to prevent immediate disaster. The issue after <9....Bxg5? 10.Nxe6> is that queen and bishop are forked, thus Black is losing lots of material or is ended after <10....fxe6? 11.Qh5+ Kf8 12.Bxg5 +-> as per game. After 9....Ndxe5, White is better but it's not an easy position to play after 10.Ngxe6 Bxe6 11.Nxe6 fxe6 12.dxe5:

Black has no 12....Nxe5, because of 13.Qh5+ Nf7 14.Bb5+, where Black is confined to the wide open king side. Instead, 12....h5 ± closes it off for now and White will be 'just' a pawn up, though ripping open the French wall is enough of a success this early on. |
|
Apr-22-22 | | TheaN: I'm a French player myself, and g5 this early on baffles me a bit. The Nf3-Nf4 configuration is no joke to face, but there's so many resources in the Black position, weakening immediately just seems weird. |
|
Apr-22-22 | | TheaN: Third post but still, I actually forgot this is a >Friday<? It really isn't. There's not much to consider, Black weakened the king side too early in the French and pays at least some price for it. The combination after Bxg5 plays itself. |
|
Apr-22-22 | | goodevans: <Brenin: After 9 Nxg5 Ndxe5 10 N(either)xe6 Bxe6 11 Nxe6 fxe6 12 dxe5 White is a P up with 2Bs and a much better position.> Of course Black could restore material equality immediately with <12...Nxe5> (okay, White has the B-pair so not quite equality) but then <13.Qh5+ Nf7(or g6) 14.Bb5+> looks extremely uncomfortable for Black even if there's no immediate win. |
|
Apr-22-22 | | drollere: i also found this puzzle remarkably straightforward. one N is burned to give the Q access, and the other to obliterate the Kside pawn cover (or recover the piece). |
|
Apr-22-22 | | Brenin: <goodevans>: You're right. After 9 Nxg5 Ndxe5 10 N(either)xe6 Bxe6 11 Nxe6 fxe6 12 dxe5 Black can immediately regain the lost P with 12 ... Nxe5. However, 13 Qh5+ Nf7 or Ng6 14 Bb5+ Kf8 leaves him uncomfortably tied down. I think he does better to prevent the Q check with 12 ... h5, attack the e-pawn with Qc7, and then castle Q-side to get his K to safety and hope for counterplay along the f- and g-files. |
