Always Dangerous

The Blackburne Defense to the Jerome Gambit leads to a tense and complicated game for both sides. As Joseph Henry Blackburne demonstrated early in the life of the Jerome, Black can generate a wild counter-attack by returning one sacrificed piece and offering a Rook as well. On the other hand, analysis since has shown that White can draw, and practical play shows he can often do better - in games in The Database White scores 68%.

Philidor 1792 - NN

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qd5+ 

White decides to steer clear of the dangers of 8.Qxh8 and grab another pawn. He hopes to show his three extra pawns will outweigh his opponent's extra piece. Philidor1792 has had significant success with the pawns vs the piece in the Jerome Gambit.


Seen previously was 8...Kg7 in RevvedUp - Fritz 8, 2 12, 2006 (0-1, 19).


Or 9.Qd3 Nf6 10.O-O Qe7 11.b3 Ng4 12.Bb2 Ne5 13.Qf3+ Nxf3+ 14.gxf3 Bh3 15.Bxh8 Qg5+ 16.Kh1 Qg2 checkmate, hattta - VictoriaBot, FICS, 2012. 


An anternate idea was 9...Rc8 seen in stampyshortlegs - Sir Osis of the Liver, JG Tourney4, ChessWorld, 2009 (1-0, 39). 

10.Qa6 Qh4 

At first glance it looks like Black is the one playing a gambit, with the subsequent lead in development of pieces. However, if White can consolidate his position behind his pawns, he can eventually put them on the march and look for balance.

As the game goes, Black uses his pieces to keep pressuring his opponent, and the point is his.

11.Qe2 Bg4 12.Qf1 Nf6 13.d3 d5 14.Nc3 Rhe8 15.h3 Bd7 16.g3 Qh5 17.f3 Bd4 18.Nd1 Kg7 19.Be3 Bxe3 20.Nxe3 dxe4 21.fxe4 Qa5+ 22. Kd1 Qc5 

So far White's pawn cover has held up, but his oppponent's pressure is relentless and his lead in development is crushing.

23.Qf2 Nxe4 24.dxe4 Rxe4 25.Re1 Rxb2 26.Re2 Bxh3 27.Ng2 Qd6+ 28.Kc1 Rbb4 29.Nf4 Bg4 30.Rxe4 Qd1 checkmate.
