PV length from 16 back to 9. Progress of -7 ply. This is where everybody has been waiting for. Technology improvements go fast these days.

Probably because of hash tables, that can cut off a PV. Who cares, it's the move being played that counts.
That said, still wondering whether a micro-controller system can beat Skipper. Can I get an EXE file?

No Skipper does no do hash cut offs. For it uses Zobrist keys so it can't trust the hash move anymore because of hash collisions. And I want to avoid spending time on errors which were caused by hash collisions.
Maybe I should go back to an old implementation that did not use Zobrist keys. Good old days.

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?
