Bitfoot (and NOT BIGFOOT, therefore not a monster) reminds me of Clubfoot instantly. And it's not by coincidence that both have feet! They are brothers...
Bitfoot is nothing more than the bitboard based version of Clubfoot. It's written by the same author Shawn Chidester in C++.
Clubfoot is currently playing in Rapidroid at 1850 ELO approx. I expect Bigfoot can do a little bit more than its brother.
