I've never concerned myself with perft in my game programs before, but is it supposed to detect checkmates in order to avoid playing past fools mates? I was wondering if perft 7 could be used to enumerate all the shortest mates in shogi. There are 29 mate positions at depth 7 : nodes = 15 086 269 6...

What GUI are using USI protocol ?

Siyam v0.46 perft 1 and 2 results:

Same results for me.

I would like to find time to make a Shogi and Xiangqi engine from my move genenerator.

Thanks, the difference is Nh4g2 and Nh4i2 illegal because of the forced promotion of the Knight.

I don't have the good result for this one, at depth 2 : FEN : 7k1/9/9/9/l2s5/6snb/9/9/8K[GG] Ki1h1 : 39 Ki1h2 : 39 G@a1 : 39 G@b1 : 39 G@c1 : 39 G@d1 : 39 G@e1 : 39 G@f1 : 39 G@g1 : 39 G@h1 : 39 G@a2 : 38 G@b2 : 39 G@c2 : 39 G@d2 : 39 G@e2 : 39 G@f2 : 39 G@g2 : 37 G@h2 : 39 G@i2 : 39 G@a3 : 36 G@b3 ...

The Lance must promote on the last rank, h2h9 is not legal.

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...
