Update: Old Dog Can Still Bite


Most chess players, if they have ever heard of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), know of the game Amateur - Blackburne, London, 1885, where the British master dismantled the opening and then destroyed it with a Queen sacrifice. They have a pretty good assessment of the Blackburne Defense, 4...Kxf7 5.Nxe5 Nxe5 6.Qh5+ g6 7.Qxe5 d6!?, giving up the Rook to distract, and, eventually trap out of play, White's Queen.

Players more familiar with the Jerome Gambit may have seen analysis that indicates that White, not Black, is better in this line.

Players very familiar with the Jerome Gambit may have seen analysis that indicates Black can draw, or force a draw, in a very, very complicated position.

All of which suggests that White can be happy when facing the Blackburne defense - if he knows what he is doing. Otherwise, that old dog is likely to bite, as in the following game.

1.e4 e5 2.Bc4 Nc6 3.Nf3 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 




8.Qxh8 Qh4 9.g3

White's Queen-escape line is, instead, 9.0-0 Nf6 10.Qd8 Bb6 11.e5 dxe5 12.Qd3.

This seems a lot saner than 9.d4, e.g. 9...Nf6 (or 9...Qxe4+) 10.e5 dxe5 11.Nd2 Bxd4 12.0-0 Be6!? when there is plenty of madness in the position after 13.Nf3 (or 13.Qxa8 Bd5 14.Qc8 Ng4 15.Qxc7+ [15.Nf3 Bxf3 16.Qxc7+ Kg8 17.Qc4+ Kf8 18.Bh6+ Qxh6 19.Qc8+ Ke7 20.Qc7+ etc] 15...Ke8 16.Nf3 Bxf3 17.Bf4 Bxf2+ 18.Kh1 Qh3 19.Qc8+ Ke7 20.Bg5+ Kf7 21.Qxg4 Qxg4 22.Rxf2 Qxg5 23.Rxf3+ Kg7 24.Re1) 13...Bxf2+ 14.Rxf2 Qxf2+ 15.Kxf2 Rxh8 16.Nxe5+. The game is even, if White survives.

However, the text in the game, 9.g3 wins - for Black.

9...Qxe4+ 10.Kf1 Qxh1+


Or 10...Bh3+, Black resigned, facing 11.Kg1 Qg2# as in LukeWarm - blackburne, Jerome Gambit Thematic, 2010.
