Re: may be a good test position ...

With McCain, set Tactical to 1 gives a big improvement. I also tried Komodo normal and with null move off but
neither was good.

LCZero however liked this quickly!

Re: Plaskett's Chess Puzzle Solved in ~15 minutes

Uri, have you tried it on a recent version of Komodo or any other of the top few engines? You won't see this result. I suspect it was just luck or due to engine parameters which make it better for some positions but worse for 100s of others. Engines in your thread which find this quick would be many...

Re: Lc0 v18 rc2 for 2080 Syzygy implementation

Re: Practice page for 3-men end-games

Is there a page listing the moves for the different pieces on this page? Or could a small piece of text be added when you select each piece
describing its moves? Thanks, this looks very interesting!

Re: McBrain v9.9 / McCain v2 Release

Thanks Mike, I'll just add that by solving I didn't mean finding a mate score, although I tried!

Re: McBrain v9.9 / McCain v2 Release

Ditto from me! Mike the position you posted (Smyslov Study on another post) is really interesting. Does the latest release get a mate score for this? I've found with Houdini 6.0.1 default settings don't solve it but Tactical=1 does quickly. Latest Komodo similarly default doesn't solve it but turnin...

Re: Mario Matous study from 1975 solved by Stockfish

I've also discovered Komodo 9 (plus the latest 12.1 version) will find Bc7 in seconds if you leave it on default settings but increase to two or four in multiPV mode in Chessbase. Would be interesting to know if any other engines behave this way.

Re: Mario Matous study from 1975 solved by Stockfish

Putting the FEN string into google comes up with a number of discussions including the following from the Rybka forums: http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=25995 It appears null move reductions make a lot of engines slower to find this. The latest Komodo 12.1.1 gets his in und...

Re: Leela ID 446 bug?

Are you referring to the site http://play.lczero.org/ ?

This has had this problem for a long while, possibly due to it being overloaded

Re: Need new Komodo release

Has there been any more thought given to having some form of position learning? I'm mainly interested in its possible use for analysing games/positions.
