Re: Turning off 50-move draw rule in Stockfish & other engines

You might give Moonfish a try. https://github.com/joergoster/Moonfish If you set "Syzygy50MoveRule" to false, this will also switch it off for the search. Thanks Joerg. Do you know when using “regular” Stockfish if you turn off the Syzygy50Moverule does the main program still enforce the 50-move-ru...

Re: Official Release of Ethereal 12.00

If your GUI provides UCI logs, both input and output, I would be happy to look at it and address the issue as fast as possible. Here's what I get if I analyse from a middlegame position and then play the move suggested. >>uci <<id name Ethereal 12.00 <<id author Andrew Grant, Alayan & Laldon <<opti...

That's interesting! But shouldn't it still be sub-linear, since the later moves should be cheaper to search (better move ordering, fewer moves to search) than the main PV?

Re: Why is MultiPV so slow?

OK, so potentially we're either looking at something wrong in my timing, or a bona fide Stockfish bug? No bug, it's intentional. When the 1st move is searched as PV move, all remaining moves are being searched as nonPV moves, too! Even those which will be searched as PV moves later anyways! This is...
