My Turn to Blunder

When playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I like to have a regular routine: I play the gambit, my opponent is surprised or shocked and plays a series of second-best moves, I gain the advantage – and then I either beat my opponent, or benefit from a timely error on his part.

You'll see most of that in the following game – except the part after "I gain the advantage", where I'm the one who comes up with the blunder. How awkward!

Here we go! 4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

A safe and solid defense. 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6

10.0-0 Kf7 11.f4

A bit better than 11.Nc3 c6 12.f4 Rf8 13.f5 Ne5 14.d4 Nc4 15.Qd3 Nb6 16.Bg5 Kg8 17.g4 Nbd7 18.Rae1 Qb6 19.Na4 Qb4 20.b3 Nxg4 21.Bd2 Qa3 22.Bc3 b5 23.Bb2 Qb4 24.Bc3 Qa3 25.Bb2 Qb4 26.Bc3 Qa3 27.Bb2 draw perrypawnpusher - joejox, blitz, FICS, 2009 11...Re8 12.d3 I thought the right move was to advance the f-pawn, but I couldn't remember (or figure out) why Black couldn't respond with 12...Rxe4. (Answer: White captures the Knight with check, then moves his Queen.)

(I almost did.) 18...Rxe5 19.Qg6+ 19...Kf8 20.g4 hxg4 21.hxg4 Nxg4

Okay, Black obliges me by giving back a piece, and I will have the advantage. 22.Qxg4 Qf6 23.Nd5 Qh6 24.f6 Simply losing the Queen. Unbelieveable. No excuse.

Was it too hard to find 24.Rf3? 24...Bxg4 25.fxg7+ Rybka 3 later said this led to a mate in 19. I'd had enough and resigned here.
