You will find patterns like 80000000 00000000, 40000000 00000000, 20000000 00000000, etc. then look for the rotated masks which are like the above, but in a different order (64 bits, 1 bit set). Then compare to crafty.exe. Look at data.c to find the pre-initialized scoring array patterns. See if you can find 'em in La Petite. :) etc.
