One day, a few months ago, I was enjoying a cup of coffee at local cafe on Geary Boulevard and decided to challenge Shredder on my iPod Touch.

I hadn’t played in a while and expected I’d put up a feeble attempt. To my surprise, I may have played a flawless game- as verified by running the game through a full game analysis with world-champion software Rybka.

This one has it all: pawn sacrifice to gain an edge in development… rook exchange sacrifice… bishop sacrifice… and finally an elegant back rank checkmate… all in just 25 moves.
