16 GB is too much for 7,5 s per move. TCEC uses 16 GB for 5 hour games with 43 cores. Which one were more expensive GPU RTX 2080 ti or Threadripper?

Re: TCEC 14 final: Lc0 just lost 3 games with tactical..

Yes current situation in TCEC is surprisingly even! BTW in CCC5 SF is leading 17,5-12,5 against Lc0 t40. Wins 6 - 1 and one obvious tactical loss for Lc0.

TCEC 14 final: Lc0 just lost 3 games with tactical..

Re: 128 CPU Stockfish Cluster Comments.

This +130 gives nice 3700 ELO! Maybe the upper limit for chess?

Re: start your engines...

Any idea what's the secret of tactical Houdini? It also gets 200/200 in Arasan suite eventually. Obviously not only nullmove change, but something else!?
