Gould Effect

I played poker last night with somebody who suffers from some disorder that makes it difficult for him to walk, talk, move his arms in a coordinated fashion, etc...the dealer had to show him his cards and put his chips in for him - he would bark out "Call", "Fold", etc.....well, this guy was just impossible to read. It was 9-way $4-$8 limit hold-em, and he beat people every which way you can over the next four hours...he wasn't just getting good cards. He was just good, and nobody could read him. What an advantage.
