An old chestnut

Here's another version of a common type of opening trap. Another unusual example is Fernandez-Garbarino, Copa Clarin 2001, which went 1.c4 e6 2.Nc3 d5 3.d3 Nf6 4.Bg5 d4 5.Ne4?? Nxe4! 0-1. Hard to believe that White was rated 2264!

My opponent "improved" over Kostopoulos-Kerimov, 2001, which continued 7...Qa5+ 8.Bd2 Bxd1 9.Bxa5 dxe5 10.Bb5#! In the final position, my opponent resigned in light of 11...Nf6 12.Nxh8 Nxe4 13.Be3, when White will be a knight up even if Black succeeds in trapping the beast on h8.
