Re: Pre-Release McCain X4

Thanks for the updates! I posted this position in another thread recently which a recent version of McCain couldn't get in 40 minutes k1q4r/p7/P3P3/1N6/8/nQ2K3/6p1/2n5 w - - bm Qd5+; id "Arves.16248"; dm 34; This version gets it in seconds (an actual # mate score) well done if it was from your chang...

Re: DTM50

I'm curious, what engine was this with? Seems quick!! :) Will check Stockfish, Fritz 14 (uses Nalimov) and a few others to see how they compare. That was with Cfish, which supports my DTM files. Unfortunately, running it with 6-piece DTM files slows it down to a crawl (once the search gets into mat...

Re: Komodo 13 released

"We think the KRPPvsKRP and KPPPvs KPP are the most useful 7 piece Syzygy files to use first." Andrew, may I ask from where are you getting these 7-man Syzygy TB files? Thanks, CMA Andrew We think the KRPPvsKRP and KPPPvs KPP are the most useful 7 piece Syzygy files to use first. Note that it is qu...

Re: Komodo 13 released

Thanks very much for the latest update! I've also been reading over the 7 piece EGTB updates you have supported but it will be a while till I download many of these. I upgrades to a 256 Gb USB drive recently which was enough to download all the 6 men Syzgy files but now this? :D Oh welll... Anyway g...

Anyone can use any engine, I don't mind about it. If you prefer Komodo it is ok to me. Each engine adds something.
Exactly JJJ, we need to think beyond just an elo number.

Re: DTM50

For example look at the various arves files https://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=32814 A lot of these positions are easy to get a TB mate score, but a mate distance is much harder. [D]4BQ2/1r3P2/4Pk2/5P1q/8/p7/P7/K7 w - - 0 1 With 6-piece TBs and 5-piece DTM: info depth 32 se...

Re: DTM50

I'm interested in getting lower mates scores for puzzles etc, not during game play. A lot of the positions in the Arves files I mentioned earlier have mate scores on them that I think could be improved on substantially. E.g: Arves 3517 3k4/2p5/2p5/K1P4p/3P1p1P/5P2/8/8 w - - 0 1 The file has mate in ...

Re: DTM50

HI just wondering if there has been any progress in Syzygy DTM generation since this thread started? Would be very interesting to know if say 3 or 4 piece could be generated and have a size significantly less than what we get for the Nalimov files. For normal engine-engine games etc these won't be o...

Re: Test Position 31.Qh8!

Komodo 12.3 and lczero (I tried the 42146 network) both get this quickly (under a minute, 4 threads)

Houdini 6.01 didn't

Re: McCain X3 Released

Thanks very much for the update Mike! I suspect something has regressed with Stockfish recently. Below is a position I found in Arves position files earlier this year. (see https://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?tid=32814 ) McCainX1 and Stockfish10 normally get out of the 0.00 line ...
