Re: Shogi Perft numbers

I have only a move generator for Shogi, and I have the same result than Ferdy, but not for the 3rd position : FEN : 5k3/+n8/1G5R1/2+s+P3b1/n+s2l+B+N2/5s+prp/9/7K1/9[SPGnpn] Kh2g1 : 149 Kh2i1 : 149 Kh2g2 : 148 Kh2i2 : 149 P@h3 : 142 S@h3 : 142 G@h3 : 142 total = 1021 I didn't spend lots of time on it...
