Re: Watch engine vs engine games launched from a cli?

Hello, Does anyone know of a chess interface that will allow you to setup an engine vs engine match via a command line AND will also display it as it's being played in a gui? I was playing around with cute chess cli but it doesn't seem to have any kind of switch to display the game in the gui as th...

Re: Andscacs nnue 0.1

Daniel and Engin could use SF NNUE if instead of integrating Daniel Shawul's GPL code into their engine they would use his dll. This has happened before, e.g. GUIs (code closed) accessing bitbase dll. You can use the dll and distribute the source code for it and you comply with the GPL and your eng...

Re: Why you play many games when testing

In that case, you would never be certain about the change you just committed, and gaining or losing ELO is completely dependent on the length of the test you're running. This is basic statistics. You fix the length of the test beforehand. By definition, with 95% probability, the Elo will be contain...

Re: Cutechess-cli and SPRT

Hi all, Looking for some help re: SPRT. I've been happily using cutechess-cli for automated testing, and it works great. I'm now trying to use SPRT to terminate matches early, and save time. I'm using the following to test a new version of my engine against a very old version (several hundred ELO w...

Re: Stockfish hangs

Very odd. It appears Stockfish issued the readyok before the nnue file was initialized, and missed some of the subsequent commands sent by the GUI. The message info string NNUE evaluation using nn-62ef826d1a6d.nnue enabled has nothing to do with the initialization of NNUE. This message is printed a...

Re: Do you test engines with or without using a book?

The book currently in use a Fishtest has a RMS bias of 30 elo which in score units corresponds to 0.043 (1% score=7Elo). Well, 30 Elo is already larger than the white advantage. I would not call that anywhere near balanced. Of course at these high draw ratios it might be better to use a very unbala...

Re: Do you test engines with or without using a book?

Replaying games with reversed colors reduces the variance of the test outcome (one should use the pentanomial model to correctly estimate this variance). So you need fewer games to reach a decision. This effect is quite substantial. Fishtest (which is the gold standard in engine testing) uses a ver...
