Here is a good example of what can happen when a player chooses a obscure, unorthodox, unusual, unconventional, weird, strange, variation to try to gain the advantage in the opening when he himself falls for a known trap. You would expect that anyone who plays the Queen's Gambit Refused Albin Counter-gambit would know about the dangers of a premature 10 ....Bh3, allowing the thrust in 11. of e5-e6, yet it occurs over and over and over and over and over again and again and again and again and again in practice.

1.d4 d5 2.c4 e5 3.dxe5 d4 4.Nf3 Nc6 5.g3 Be6 6.Nbd2 Qd7 7.Bg2 0-0-0 8.0-0 h5 9.b4 Bxb4 10.Qa4

Most Every Patzer knows that Black can't play 10 ....Bh3 here.

Bh3

But clearly not every Wood Pusher.....

11.e6 Bxe6 12.Rb1 Bh3? 13.Ne5! Nxe5 14.Bxb7+ Kxb7 15.Qxb4+ Kc6 16.Ba3

Black resigned here, but we let Fritz play out the game to mate.
