Re: Komodo Syzygy evals.
Hello:
Probably it is ±#(1801 - X) instead of ±#(1800 - X). Better help is needed.
But I see: 63.- h5? instead of 63.- Qhe8#. I guess it does not relate with Distance to Mate (DTM) versus Distance to Conversion (DTC), isn't it? I am not an expert on TB as everybody can see.

I think it is a particular output, something like ±#(1800 - X), where ± indicates the checkmate from the side to move (+ if it is in favour of Komodo or - if it is against it) and X means 'mate in X moves' (moves, not plies). For example, look at 59.- ..., Kf8 (-#1796) by Komodo and 60.- h7 (#4) by SF. More strange are 61th and 62th moves by black (both -#1799 instead of -#1798 and -#1799 respectively).Hurnavich wrote:[d]7Q/3k2p1/1K4Q1/8/7P/8/8/8 w - - 0 63

Re: Komodo Syzygy evals.
The thing is Stockfish and Houdini see the mate using Syzygy
Komodo appears to not see it so it is a problem with Komodo is it not?

Re: Komodo Syzygy evals.
when set to 5 man probe works no problem so looks like a 6 man K problem
Hope a fix can be found

Re: Komodo Syzygy evals
Quote from our Syzygy implementer Jeremy Bernstein:
"OK I do see the problem with the 6-man bases installed. This is the DTZ problem: the Syzygy bases are preferring a pawn move (resetting the DTZ clock) to a queen move, even if the queen move is mate! The solution to this would be to continue to search on the move list returned, but that might result in some performance drops. It would, in any case, need to be tested.
The "nonsense score" is a tablebase win, as explained in the documentation."
