Ok, I should be able to do that, I ran back several games where I could significantly shorten the win by playing human. (but maybe before the AI recognised a forced win. Hmm.
Another nuisance "bug": when I finish a game with AI vs AI and restart, the board clears. then I click on the play arrow and the AI starts to work (Ludii AI shows color dots for example, and the II pause symbol shows) And then the AI stops, and Shows the play arrow again without having made a move. After that I can click the play and the game starts.
No big deal, but often I forget, click the play, and go off to do something else only to return and see I actually didn't start the game yet.
Oh, and in this game, it is searching to depth 9 but making avoidable moves that cost the loss of say 2 pieces and 4 points going from 7:10 to 7:6 in a single turn as if it doesn't see the captures - it might be because of how the captures are implemented as a consequence in an independent select in a do, after the moves are completed...
Just now saw it twice move to create a solid block of pieces, which causes the middle one to die on the NEXT turn (provided the opponent doesn't pass. losing 6 points.)
Looks like they were unavoidable for those two, as the opponent could have moved to kill otherwise - just wasted initiative.
Backed up to another point where white had a 7 point lead, and 7 passes could bring that to a win with a one point lead. but to be fair, the AI could only see 10 moves ahead at that point, not 14. changing from 10 to 300 seconds brought it to depth 13, so it still missed it, but the move it chose instead cut its lead to 2 on the opponent's next turn.
So I'm still looking... I guess its finding them OK, its just a case of humans being able to short-cut such cases to see at greater depth than other cases... something like queening pawns.
