Keep that kung fu bunny away from me or I'll kick his ass

I rarely think to sacrifice the Queen. I might win more if I did. 

sacrificing your queen needs a precise calculation; because if you didn't manage to calculate all the possible moves, there's a chance for opponent to force an endgame and your down a piece.

I sometimes sac my queen when I play white vs the Sicilian http://www.chess.com/forum/view/chess-openings/the-bryntse-gambit

I just sacrificed my Queen for a checkmate! This is a game played between two amateurs with inaccuracies/mistakes on both sides of the board - my annotations are light and also may not be the best: any constructive comments or suggestions are most welcome.

Oh dear...I just realised...I made a blunder...thanks for pointing that out
