Re: Anyone know of a way to download FR fens(chess960) by FR position number?

On the FR stuff, just not interested in doing any UI around it mainly right now so not sure the point to add fen position numbers to PGN. Anyone know by the way if you even did add a fen position to PGN is there a PGN tag for that? I guess i'm wondering how custom this all is. Are there any agreed ...

Re: Nose Breaker

I was just told that "Lomonosov" means "nose breaker". I have always admired that great work done on the Lomonosov 7-piece tablebases, and think this is a great name for them, although I know they were named for the university they were computed at. and the university was named after this man .. ht...

Re: Lantern Chess an ICC Interface has been removed from Google play. no warning. no real idea why

I did 16 new screen shots recently, 8 for tablet and 8 for phone, and apparently the tablet console shot screen capture captured someone saying a bad word "sh*t" but without the *. I updated that screen shot and it let me republish so hoping that fixes it. Everyone knocks apple but apple would have...

Re: Leela Chess Zero 42565 vs Stockfish 140619

What is the cost and what is the return. In chess engine terms, playing with ponder on put a lot of strain on the system resources. Leela need 1-2 threads itself and many recommend one thread for the OS. Tweaking SF threads to 29 from 32 it's not the end of the world. It's a necessity for stability...

Re: Pre-Release McCain X4

I am not a fan of the "LC0 style scoring." Worse, you cannot turn it off when it sees a win. I chose ce in the UCI options. Analyzing this position: 8/8/3R3K/P7/8/4ppk1/8/8 w - - I get this: Avoid move: Best move (McCain-X4-modern-64): Rd6-g6 Not found in: 01:00 Found 510 tablebases 1/2 00:01 108 1...

Re: Pre-Release McCain X4

I already hinted to a possible cause in one of the former McCain threads: http://talkchess.com/forum3/viewtopic.php?f=2&t=69849 From what I have googled, e. g. uint_fast8_t must NOT necessarily be 8 bits, it can be larger ...

Re: Pre-Release McCain X4

Thanks for the updates!

Re: WCCC vs TCEC Chess Engine Competitions..

On the red, you misunderstood, I wasn't referring to the R/F case -- although I admit my wordings could be interpreted that way :lol: :P -- but to an organization that wants to stick to an old outdated formula. Surely the R/F case has damaged their reutation but it is not the main reason of their d...

Re: max number of pseudo legal move

Logged Sapeli's maximum moves from standard games against Fairy: https://pastebin.com/HU2CQvZm 79 moves is the maximum currently. I think 128 is plenty for gameplay. For analyzing 256 is bullet proof. I will be surprised if 79 moves is the maximum for human games. There are many games between child...
