Wing Gambit!
Maybe I've been reading too much Nimzovich lately but I have to say the whole idea behind an 'optimistic' struggle for the center (in the sense that once you've gained control you 'hope' to have a winning plan) has inspired me to try very unorthodox things to gain this control. This game was quite interesting in that sense. White sac's a pawn with little intention of getting back but in exchange for a slight lead in development, activity for his rooks, and most importantly, greater control of the center. Worth it? I believe so.
Here is a very interesting wing gambit game! Enjoy!
