Sweep away all the pieces before doing a Nimzo-whymustIlosetothisidiot?-witsch

Well... To be perfectly honest, this is how I start almost all of my tournaments. The first game I have to lose a pawn, or some advantage, and then I can kick it into gear and focus on the game. It's weird, but I always play better after that initial mistake.
