Is that 3 in the output really 3 centiseconds?! Impressive. What's your LMR and pruning like? RookieMonster finds it in 13 ply, but it takes 105 seconds and searches considerably more nodes than Isa (61x as many). I've got LMR and null move, but not futility (it always seems to hurt its play).
Anyway, to contribute to the Skipper discussion: Henk, even if it doesn't find mate right away, if you let Skipper play itself from this position, does it make progress in driving the lone king to the edge and certain doom?
3 seconds yes but so false PV
My lmr is very primitive : reduce by 2 depths if have move >=5 , I have nullmove and futility pruning outside the loop moves
May be the eval make the diference too ? Big penalty for a bare King on the edge

Note: Winboard expects the time component of the output to be in centiseconds. Still 3 seconds compared to my 105...
No worries on the PV. Probably just cut short by transposition table hits.

Isa regularly out-depths RM, so I don't think it's just the eval. Maybe the futility pruning is the key then. Bummer it keeps hurting mine when I try it.

I'm extremely confused by the data in your "Time (seconds)" column. There are multiple instances in which the time reported at depth N+1 (or, actually, N+10, which I don't really understand) is LESS than the time reported at depth N. Look at the reports from depth 690 and 750, then the next depth.
What's going on here?

I'm extremely confused by the data in your "Time (seconds)" column. There are multiple instances in which the time reported at depth N+1 (or, actually, N+10, which I don't really understand) is LESS than the time reported at depth N. Look at the reports from depth 690 and 750, then the next depth.
What's going on here?
That has confused me as well a while ago. Search output of Skipper is non-standard (well, that's the only non-standard thing in it ...) by not accumulating nodes and time but reporting these for each single iteration. Also depth is 10 * the normal depth, obviously just for fun.

Skipper urgently needs a rewrite from scratch. Believe me, please.

Probably but that would be no fun. Also I first want to get rid of zobrist keys for I don't trust hash moves any more because of that.

OK. Less is more. Think small. Looks like it is slower too.
