Re: Trio Tournament 2021
Thanks for testing
I don't know Sunfish. It's not in the CCRL list. It's just 111 lines of code. I assume it's a UCI interface built on top of a chess library
I hope that it does accept those promotions though it doesn't play them itself? Rustic _will_ underpromote to R, N or B in a few situations:Sunfish supports castling, en passant, and promotion. It doesn't however do minor promotions to rooks, knights or bishops
- When it is actually the best move (for example, to set up a knight fork)
- To avoid stalemate (promoting to rook instead of queen)
- Sometimes it looks as if to promote to something else but a queen for no reason, but I assume it does this when it's convinced that the piece is going to be captured immediately; then the lower promotion will seem to lose less material.

Re: Trio Tournament 2021
Well, Trio Tournament became The Tournament of the Five.Basically there are two tests in my tournament:mvanthoor wrote: ↑Tue Mar 23, 2021 12:05 amThanks for testingNoonianChess is 1804 Elo in CCRL, so it should be a good match for Alpha 2.

1.-Rustic vs. Noonian;
2.-the status of the two engines written in Python (I can't see a progress in the last Sunfish; PyChess 0.99.4 plays quite fun-it's safe over Virutor 1.1.2, used as a marker- I think it has around 1400 Elo points / CCRL Blitz). Neither CEGT nor CCRL tested the engines written in Python, except for Feeks (a 967 Elo point engine). Not even A0lite -using pytorch net evaluator - is not tested ......... I have no idea why;
The last Rustic plays nicely. Congratulations !
My tournament is very flexible. I can add engines, I can increase the number of games ..... I will see ....

Re: Trio Tournament 2021
Not sure if it is still possible to add engines, but I would like to see Zahak (my first chess engine, and still working on it) in the list. This is the link to the Windows 64 bit: https://github.com/amanjpro/zahak/relea ... -0.3.0.exeSylwy wrote: ↑Tue Mar 23, 2021 9:46 pmWell, Trio Tournament became The Tournament of the Five.Basically there are two tests in my tournament:mvanthoor wrote: ↑Tue Mar 23, 2021 12:05 amThanks for testingNoonianChess is 1804 Elo in CCRL, so it should be a good match for Alpha 2.

Re: Trio Tournament 2021
Super cool! Interestingly Zahak 0.3.0 does poorly against Rustic here!
