  3. Small inaccuracy concerning 50-moves-draw: it's actually 51 moves

No big deal, guys: I figured it out by accident resp. bad technique :o

I tried to reproduce it, it's 51 seemingly.

Probably because I started from a given position?

Looks like a programming error to me indeed... it seems the computer doesn't claim because it only made 49 moves itself. And then, instead of moving, on the next move it claims because it's possible. Could be a wrong interpretation

I am confused for three reasons:
1. I don't know why the AI didn't claim a draw on move 50
2. I don't know why you didn't claim a draw on move 51
3. I don't know why the AI claimed a draw on move 51
