Breaking News (29.11.2025):The tour ended..congratulations and many thanks to all eng programmers!Via latest new update: 5 Top engines entered.. including Reckless as well,Which comes with small net (11.7 MB), In other words, just imagine again!!Since no any engine to be so small and in same time to pass 3800+ barrierAnd and and... Waldemar is Waldemar, his SF-PB one seems to be best!!2nd Revolution by Jorge Ruiz Centelles, who is another unique talent too!On the other hand, as usually, Anton CES's engines performed very good..As we see, Spectral 12 managed to be 3rd really another amazing score!Sure as same words are going for many many other great authors as well!Btw, due to requests...Waldemar's Number One (SF-PB 261125): DownloadAnd I hope next releases to be compiled 'without' embedded net! Reason?My tournament machine is full via same default net nn-c0ae49f08b40.nnue You may know, everything when too much is headache, correct if I'm wrong..Moreover, it's not logical if all via same net, to be included in same package!As last words, it seems all stable..no time forfeits or no any crash recorded!Meanwhile, for more info about latest new ongoing competition OpenChess
LXV Current Champion: SF-PB 261125 - Congrats to Waldemar, SF Team!
