The Queen’s gambit is commonly seen in online chess games at my level. I used to play the Slav defense but grown bored of it. With some help from Google, I found the Albin counter-gambit variation in which Black sacrifices his own King pawn. The novel part of this opening is that quite often, White is led into a fatal trap known as the Lasker trap. Supposedly, the great Emanuel Lasker fell for this trap, although I have no references. Very rarely does one see an underpromotion (a knight in this case) as early as the seventh move. So when this position occurred in an online game I played, I was more than happy.
