No Way Out



Still unwilling to concede the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) to the Nibs Defense (see "Sometimes"), Philidor1792 recently explored a "theoretical novelty" at move 9 in a couple of games, and discovered that it did not lead to escape.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+ 






9.Ke2

This is a TN, as an alternative to 9.g3 Nf6+ 10.Kd1 or 10.Kf1.

9...Qf2+

An improvement over 9...Qg4+, when White was able to wrangle a draw with much, much effort, against a human opponent, i.e. 10.Qxg4 Nxg4 11.d4 Bb6 12.Kf3 N4h6 13.Be3 c6 14.c4 Ke7 15.Nc3 Ba5 16.g4 Bxc3 17.bxc3 d6 18.g5 Nf7 19.f5 h6 20.h4 hxg5 21.hxg5 Rxh1 22.Rxh1 Bd7 23.Kf4 b5 24.cxb5 cxb5 25.e5 Bc6 26.Rh7 Kf8 27.g6 Nfh6 28.Kg5 Re8 29.Bf4 Bd5 30.f6 gxf6+ 31.exf6 Re2 32.Bxd6+ Ke8 33.Rxh6 Rg2+ 34.Kh5 Nxh6 35.Kxh6 Bxa2 36.Bb4 Rh2+ 37.Kg7 Rg2 38.Kh6 Rf2 39.Kg7 Rg2 40.Kh6 Bd5 41.Kh7 Rh2+ 42.Kg7 Rf2 43.Bc5 a5 44.Ba3 Rf3 45.Bc5 Rf4 46.Ba3 Rf3 47.Bc5 Rg3 48.Bd6 Rg2 49.Kh6 drawn, Philidor1792 - guest276, Internet online game, 2012.

10.Kd1 Ng6 11.d3 c6 12.Qg4 Kc7 13.Qg3 Qxg3 14.hxg3 d6 



White's "Jerome pawns" are up against two extra Black pieces, which is a bit too much.

15.f5 Ne5 16.Bf4 Ng4 17.Ke2 N8f6 18.Nd2 Re8 19.Kf3 

The King rallies his troops, but the defense is too difficult.

19...g6 20.fxg6 hxg6 21.Raf1 Nh2+ 22.Rxh2 Bg4 checkmate
