Re: Fat Fritz update

The latest update is Fat Fritz 1.1 with changes to Cpuct, Fpu, Policy temp, NN cache and couple of others. Tests are required to see where it stands. Here is how Fat Fritz 1.1 is performing currently against Stockfish. So far the results look very good for the Fat Fritz update! Fat Fritz 1.1 vs Sto...

Re: Repeating games with switched colors reduces Elo error. All matches should be done like this

This only applies to tests with the same opening book for both sides. It makes intuitive sense that the results will be more accurate if player A and player B play both sides of all openings. But I couldn't find any empirical results so I wrote a utility to test it out myself. First, I've compared ...

Re: Repeating games with switched colors reduces Elo error. All matches should be done like this

I disagree. Why isn't the performance of 1.g4 or 1.f3 tested for the engine? It's a subset where most engines underperform so we prune those variations as bad. If an engine really underperforms in some variation of the Semi-Slav, then forcing this engine to play it makes as much sense as making it ...

How bad can it be
Making me waste 15 minutes of my life checking and RC that doesn't work. I'd rather not risk those minutes.

Re: Repeating games with switched colors reduces Elo error. All matches should be done like this

When an engine is rated, it should not be rated over a tiny subset of chess positions it likes and can go in if using an opening book meant to exclude most of the lines it does worse in. I disagree. Why isn't the performance of 1.g4 or 1.f3 tested for the engine? It's a subset where most engines un...

Re: a killer was born last night.

Thanks mwyoung. Yeah, I've had really bad experienced with Release Candidate versions in the past, to the point of regretting not waiting for the final release. If there's something broken in the RC that makes me waste time fixing it only to see the final release had no problems that'd be the same ...
