What Are You Playing?

The following quick game shows the risks of playing "thematically" instead of "concretely" - as in, not what your opening suggests, but what is actually on the board.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Qg5

I can imagine Bill thinking: "I'm playing the Jerome Gambit. What are you playing??" His opponent makes the thematic attacking move in the BSG, but he should have stayed in the main lines with 6...Kxe5.

I was surprised to find 52 games in The Database with this position, with White scoring 61%. Only 39 games feature White's next move, which bumps the scoring up to 65%. Sadly, 37 games feature Black's terminal response - and White still scores only 64%.

This game shows the way to a full 100%.

7.cxd4 Qxg2

As intended, but allowing checkmate. 

8.Qb3+ Kd6 9.Qd5+ Ke7 10.Qf7+ Kd6 11.Nc4+ Kc6 12.Qd5 checkmate
