Theory From the Thematic Tourney (5)

The Blackburne Defense to the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 B5 4.Bxf7+) is probably the best known way for the second player to respond to the opening sacrifices – by offering a sacrifice himself, Black hopes to bring the game to a quick tactical end in his favor.

The current ChessWorld Jerome Gambit Thematic Tournament features three Blackburne Defenses, and, fittingly, the player "blackburne" is involved in all of them.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6


This is Black's offer of a Rook. Although in theory White can take the Rook and live – there is a complicated draw that Black can put together, found by Chandler and Dimitrov – over-the-board the capture can be filled with dangers for the unwary.

We've already seen the game Luke Warm - blackburne, Jerome Gambit Thematic Tournament, ChessWorld, 2010, where one mis-step by White was all it took to give Black the win (0-1, 10).

On the other hand, stampyshortlegs - blackburne, Jerome Gambit Thematic Tournament, ChessWorld, 2010 (1-0, 29), showed that Black needs to be precise in bringing home his win after the Rook sacrifice: about his 10th move I commented
The problem with this move is that White has 32 possible responses: 31 lead to an advantage (most of them mate) for Black. However, 1 leads to a win for White.
The third Blackburne Defense game features blackburne with the White pieces: blackburne - CheckmateKingTwo, Jerome Gambit Thematic Tournament, ChessWorld, 2010. It is not yet completed, but it can be noted that in the opening blackburne refused the Rook, playing 8.Qf4+ instead. After 8...Qf6 9.Qg3 Nh6 (an oversight) 10.d3 Bxd4 11.c3 Bb6 12.Bxh6 Re8


White was better, but the game continued (and continues) in a very complicated fashion.
Thus, while the theoretical chances favor White in the Blackburne Defense, the practical chances favor Black.
