In a recent blitz game, I was playing the Smith-Morra gambit. After my opponent insulted be by saying that a free pawn was a stupid move, I proceeded to crush him as follows. 1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 Nc6 5.Bc4 Nf6 6.Nf3 d6 7.e5 Nxe5? 8.Nxe5 dxe5?? 9.Bxf7+ Kxf7(forced) 10.Qxd8 1-0
Of course this trap rarely works against better players, but I had a suspicion that he was a newbie. After I played him, I found out his rating was ~800 >_<
So does anyone else have accounts of how they owned players audacious enough to insult their chess?
