found in iteration #48 ???

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

We have even a M10 found at iteration 77 lol
Sure Skipper have a little problem somewhere

Rewrite only made it slower. (See my previous post). Depth is only a relative value.

Winter finds mate on my Lenovo T470S in about half a second, but 3 million nodes (probably would be less in other engines but for some nodes it makes and unmakes some moves during move generation to ensure legality, which inflates nodecount). The evaluation terms that could effect search are King piece square table, queen activity and the distance of the black queen to the white king. The engine doesn't use null move pruning in the diagram, but takes advantage of LMR and razoring.

Stockfish is interesting. Took just 0.2 seconds and only 800'000 nodes, as expected, but didn't find the best mate until depth 27!

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.

Thanks, Sven!
