Re: Lc0: Kiudee setting is very strong

I had a run in my LTC chess engine ladder, (90 min 45 sec/per move) using latest Lc0 version as of jan 28, with blass backserver (no gpu). Lco works very well up to middle game, approx up to move 35, then it loses eggregiously afterwards. I suspect configuration using blass must be quite different....

Re: Why is MultiPV so slow?

For future reference: I tried integrating manual multi-PV in my scripts, and it was markedly slower than just regular multi-PV. I have no idea why it didn't work this time; perhaps it was the different position, perhaps these things pan out very differently with many threads, perhaps the hash size ...

Re: Engines playing Musketeer Chess, good price

KingSlayer-Aramis 0.3 does not recognize queen promotion.

It played as black and after white queen promotion it did not bother evading from check and played Rxd1 which was illegal.

Re: Why is MultiPV so slow?

So, of course I get why MultiPV is much slower than a regular single-PV search; you can't use the cutoffs and have to research suboptimal moves to score them. But still, the slowdown seems extreme. Right now, I'm searching the same position on Stockfish 11 on very similar hardware (basically two-so...

Was the white Bishop on c1 captured? And did the Fortress not disappear on that move as a side effect?
Yes.
