I have them all, including 0x88. I don't think I have squeezed every bit of
speed out of my quick 0x88 version, but it was slower than my current bitboard
version especially for generating only captures (which is more important than
the "moves generated/sec" statistic in my opinion).

Basically I can do around 850k times/sec a GenerateCaptures(). I didn't manage
that with 0x88.
