The following game gave me a good laugh. I've included a lot of sidelines, and some decent earlier games (available from The Database). Black (rated almost 400 points higher) plays just fine - until he takes his eye off the ball for one second. That is enough for White to grasp victory from the jaws of defeat.

Several times in the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game – a pretty serious struggle – my opponent made shocking moves that had devastating effects – on his own game.
I couldn't figure it out at all.

This capture prevents d2-d4 by White, at the slight cost of making the e-pawn passed.

One difference between computer and human chess players is that the former is not embarassed by a repetition of moves. Here 11...Bg4 is what Black needed to play, keeping a small edge. This is not the last time that my opponent's reluctance to play that move costs him the advantage.

fortytwooz wants to attack my King, but 13...Bg4 was a bit more to the point.

Planning to swing the Queen Rook over to join the attack.
I can't sit still, I have to activate the "Jerome pawns".
15.d4 Bb6 16.f5 Qf7

This came as quite a shock. There are other ways to give the piece back, including the cold-blooded 17...h5. Choosing this way, Black probably should have put his Queen on h5 at move 16.
18.hxg4 Kd8 19.e5
Here come the pawns.
Still, after the game Rybka suggested that stronger was some piece development first: 19.Ne5 Qg8 20.Be3 Kc8 21.a4 a6 22.c4 Rd8 23.b4 h5 24.g5 Qe8.
