If you run crafty on a machine, and cut the clock speed by 1/2 every now and then, the playing skill will drop steadily until some threshold value, then it will plummet... because you just dropped the search depth into the range where my null-move search assumptions begin to fail badly. A non-null program won't have that threshold to cross and at some point it will suddenly start to kill mine when the hardware gets too slow. Not uncommon at all... Whether this is Vincent's issue or not is unknown.. I only know that his program plays _very_ strongly on ICC... Against Tiger, against mine, against anyone... It never pays to take someone too lightly...
