In the following game, Black puts together a defense against the Jerome Gambit that appears, at first glance, to be quite reasonable. That is one of the problems in facing the Jerome - it appears to be so reckless that any "reasonable" response will be effective. Not so.

It seems reasonable to grab a pawn after returning one of the two gambitted pieces. The problem is the plan squanders most of Black's advantage.
7.dxe5 Bxe5 8.Qd5+ Kf8
9.Qxe5 Qe7
The exchange of Queens may cut down on White's attacking chances, but it gives the first player a simple game, a solid pawn up. We have seen a number of games where this strategy has failed against angelcamina.

14.f3 Kf7 15.Bxf6 gxf6 16.Nd5 c6 17.Nf4 Rg8 18.Rad1 d5
All things being equal, going down a second pawn is not a good idea, even in bullet chess. It might only work if the player is moving faster than his opponent, and is ahead on the clock.

A mistake that ends the game.
