Re: Pre-Release McCain X4

I am not a fan of the "LC0 style scoring." Worse, you cannot turn it off when it sees a win. I chose ce in the UCI options. Analyzing this position: 8/8/3R3K/P7/8/4ppk1/8/8 w - - I get this: Avoid move: Best move (McCain-X4-modern-64): Rd6-g6 Not found in: 01:00 Found 510 tablebases 1/2 00:01 108 10...

Re: Pre-Release McCain X4

Probably needs an aligned allocation. Objects can be different sizes because of the OS and compiler. For instance, with GCC on a 64 bit Linux, long is 8 bytes but on 64 bit windows it is 4 bytes. I didn't even look at the code yet so this is a guess. Strange that an assert was used since it sounds l...

Re: Where are the funs of Leela?

Nobody is ever satisfied with the openings, even though competent people like Cato and Jeroen work on them. Every good chess player wants their favorite chess opening included. You will never satisfy everyone. Please reread the sentences you posted and see if they make sense in chess. They don't. T...

Re: Leela, such a great engine (and innovation)?

And finally, there is a huge difference between "I am convinced." And , "It has been proven." What's the difference? Really, I keep saying "Magnus Carlsen", "Magnus Carlsen" like a parrot, but it hasn't been proven to any degree that he's the strongest chess human on earth, yet "people being convin...

Re: Where are the funs of Leela?

As long as the opening is not too lopsided, reversing the opening is a good ides. Nobody is ever satisfied with the openings, even though competent people like Cato and Jeroen work on them. Every good chess player wants their favorite chess opening included. You will never satisfy everyone. The main...

Re: Leela, such a great engine (and innovation)?

The key word here is prove. I don't know if there is someone within 20 Elo, but if there is,we can't prove who is smarter on the basis of the games played.
