Hi all, > eval evaluates the current position only, not the possible checker plays > or cube action, so the move filter is irrelevant. The evaluation is done > at the ply level you asked. well at +1 ply you could evaluate more than the best move as well, only due that BG has much better evaluation function than chess we can do that :)
> The best move is clear enough that there are no other "moves within > equity 0.16" and the evaluation stops at 0 ply. Ah, ok, that explains the behaviour. I feel it is a bit surprising, getting 0-ply when asking for 2-ply but that surely makes sense performancewise. > > Moves 2 and 3 are now close enough at 0 ply to be evaluated more deeply. > > Another possibility is to raise n in the "keep the first <n> 0-ply > moves". It probably makes sense only for analysis or hint, not for > actual play or rollouts. It costs a lot of time and only rarely finds a better move.

More? Something somehow correlated to the "more moves > within equity" parameters? I completely agree, a wide filter is probably the better solution. Thanks for your response. best Frank
