Jerome Gambit: Countering the Counter-Attack

Here is another look at the 6...Qh4 defense in the Jerome Gambit, discussed in the previous blog post. Again, Bill Wall has the White pieces. This is pretty heavy going, and there is plenty to study in the notes, too. Or, you can just enjoy the main game, as, after a dozen moves, Bill decides enough is enough and goes after the enemy monarch.

It is time for White to start putting the pressure on.

Curiously, Stockfish 8 prefers 13.Nd5 and recommends that Black sacrifice the exchange to keep an edge in the game: 13...Rg8!? 14.Nxc7 Ne5 15.Nxa8 Bb7 16.f3 Qxc5+ 17.Kh1 Bxa8.

Going after the King makes more sense to me.


Now it's time for the Knight to step in.

14.Nd5+ Kd8 15.cxb6 axb6 16 Qf7 Qd4

Centralizing the Queen, stepping out of the possible exposed attacks by White's Queen (after the Knight moves), and protecting the f6 pawn. Alas, it leads to disaster.

17.Rad1 Qxb2 18.Rfe1 Ne5 19.Qe7 checkmate
