Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

I just want to say that I think the distinction between "tactical" and "positional" problems is rather arbitrary and not so useful, because in real chess games good positional moves are found by tactical details. For example, let's say that rook on the 7th rank is usually good (with whatever condit...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

snip... If we know what "tactics" is, then we know that WAC suite is a very tactical test-suite. I trimmed it from 300 to 145 positions which have a unique, game-changing solution. Komodo solves all of them in under 5 seconds/position, and the vast majority of them at depths 1-12 (125/145 solved), ...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

STS is not great positional test suite and this became clear precisely with Leela. I have my own 3 year old positional opening suite containing 200 positions, which proved to withstand the Leela challenge, Leela is outperforming all other engines by a wide margin. Here are solved positions at 1 nod...

Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

Can you admit bluntly that Leela on an RTX GPU is objectively MUCH stronger positionally than any of these Stockfishes, Komodos etc even on 64 core machine (doesn't matter how many cores)? And that STS fails miserably in showing that, while it claimed to measure exactly that? You don't want to unde...

Re: ChessBase's prophecy of 2004 fulfilled in 2019

Everybody knows by now that Kasparov received help from Kimo during those matches. Not really, it turns out Kasparov has never cheated by using a program like Kimo while playing chess, and the positions mentioned in the article were outside Kasparov's preparation so Kimo couldn't have anything to d...

So I'd say these 200 positions are great for Leela, which doesn't mean they are as great as for testing other engines...
