Sang Froid


The ongoing RedHotPawn.com Jerome Gambit tournament continues to produce interesting and educational games.

Be sure to follow the games in the notes, too, for extra excitment!

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 7.Nc3 



Sang froid. White answers Black's wild counter-attack (which leaves two pieces en prise; see "A Pie-in-the-Face Variation") with a rare, but simple developing move. Anything is worth a try in such a precarious position.

For the adventurer with White, despite what a computer player might say about the position, it is reassuring to know that in 222 games in The Database, White scored a scintillating 67%!

7...Bb4

Instead, 7...Nd3+ was the odd idea of the coputer Milobot, in a crazy game that veered all over the place: 8.cxd3 (8.Qxd3) 8...Bf8 (8...Bxd4) 9.Qf3+ (9.Qb3+ or 9.O-O) 9...Qf6 10.Qh5+ Qg6 11.Qd5+ Ke8 12.O-O a6 13.f3 Ra7 14.Bf4 b5 15.Bxc7 Nh6 (15...Rxc7 16.Qe5+ Kd8) 16.f4 Qf7 (16...Rxc7) 17.Rae1 (17. Qe5+) 17...Qg6 (17...Rxc7) 18.f5 Qg4 $18 19.Qe5+ Be7 20.Bd6 Qxg2+ 21.Kxg2 Kf8 22.Qxe7+ Kg8 23.Qf8 checkmate, LeoJustino - MiloBot, FICS, 2012. Wow.

7...Ng4, like the text in the game, also preserves Black's advantage 8.Qf3+ (8.g3 Qf6 9.Qxg4 Bxd4 10.Nd5 Qxf2+ 11.Kd1 d6 12.Qh5+ g6 13.Qh4 Qf3+ 14.Kd2 Qxh1 15.c3 Qg2+ 16.Kd3 Be5 17.Bh6 Qh3 18.Qd8 Qxh6 19.Qxc7+ Ke8 20.Rf1 Qg7 21.Qc4 Be6 22.Nc7+ Kd7 23.Qxe6+ Kxc7 24. Rf7+ Qxf7 25.Qxf7+ Kc6 26.Qc4+ Kd7 27.Qf7+ Ne7 28.Qb3 b6 29.Qb5+ Nc6 30 b4 Rhf8 31.Qd5 Rf3+ 32.Ke2 Raf8 33.b5 Rf2+ 34.Ke1 Bxc3+ 35.Kd1 Rd2+ 36.Ke1 Rxd5+ White resigned, CoachCrupp - mathgk, FICS, 2010) 8...N8f6 9.dxc5 Nxh2 10.Qh3 Qxh3 11.gxh3 Nf3+ 12.Ke2 Nd4+ 13.Kd3 Nc6 14.a3 b6 15.Be3 Ba6+ 16.Kd2 Ne5 17.Rad1 Rhe8 18.Kc1 Nc4 19.cxb6 cxb6 20.Bf4 Nxe4 21.Nxe4 Rxe4 22.Rxd7+ Ke6 White resigned, Darthnik - picator, FICS, 2011

8.dxe5 

The wildness continued after 8.O-O with 8...Ng4 9.h3 h5 10.Qf3+ Qf6 11.hxg4 hxg4 12.Qxg4 Bxc3 13.bxc3 Qh4 14.Qf5+ Nf6 15.f3 d6 16.Qf4 Qxf4 17.Bxf4 b6 18.e5 Nd5 19.Bd2 Ba6 20.Rf2 dxe5 21.dxe5 Rae8 22.f4 g6 23.Re1 Ke6 24.g4 Rhf8 25.Kg2 Ne7 26.Kg3 Bb7 27.c4 c5 28.Bc3 Ba6 29.Re4 Rd8 30 a4 Rd1 31.Rh2 Rg1+ 32.Kf3 Bb7 33.Ke3 Rxg4 34.Rf2 Black forfeited on time in a winning position,  PLURkidIT - CEZRUN, FICS, 2007.

8...Bxc3+ 9.bxc3 Qxe4+ 10.Qe2 Qxe2+ 11.Kxe2 Ne7 



A lot of the tension has been taken out of the position, and with only a pawn for his sacrificed piece, White needs to find a way to make use of his open lines and Black's slightly unsafe King.

This time, he is not successful.

12.c4 b6 13.g4 Bb7 14.f3 Rae8 15.Bb2 Ng6 



16.Kf2 Nxe5 17.Bxe5 Rxe5 18.Rad1 d6 19.Rd3 Rhe8 20.Rf1 Re2+ 21.Kg3 Rxc2 22.Rd4 Ree2 23.h3 g5 24.f4 Re3+ 25.Rf3 Rxf3 checkmate
