Re: top engines vs 2400 engine knight odds matches

Thanks. Unfortunately it is just as hopeless at giving knight odds as the newer Lc0 networks are, they both just give away pieces almost as if they were playing giveaway chess. It's easy to see the reason: the eval for queen odds is less negative than the eval for pawn and two move odds (remove f7,...

Re: Syzygy DTZ data explaination?

Fathom ranks (and scores) all winning moves the same unless the probe code indicates the position has been repeated (i.e. that the engine is failing to make progress by itself).

Re: top engines vs 2400 engine knight odds matches

You can try this with Stoofvlees as well (you should have a copy). I expect it to do even better than lc0. I've been too busy to check it out, but since you made this comment I'm motivated to check it out next week when I should have time. Is this the chess analog of the Leela Go situation where th...

Re: Allie is very attractive

The original lc0 and Komodo 13 also play Ke2 here. As does Stoofvlees.

Doesn't seem hard to find.

Re: Will TCEC need to rewrite their rules?

Tablebases (and the associated access code) are considered an exception for very practical reasons. If using the third-party access code wasn't allowed, then every author who wanted to use EGTB would have to invent their own format (as Syzygy for example has no formal specification that you could pr...

Re: Some speed tests with Leela and Allie

Why you think that in the case of given Net and given binary there is no any connection between speed and the chess power? Because the speed changes if you change the cache size (reason, see previous post). (There's still a positive correlation in the general case, but you can come up with patholog...

Re: My failed attempt to change TCEC NN clone rules

the poster child of boom bust AI investment development cycle. Each boom has been accompanied propaganda-wise on dreams of “well if they can beat humans in chess ...” and each bust on failure to actually deliver on the dreams. So, I would posit, computer chess is about bullshit also. Extracting cop...

Re: My failed attempt to change TCEC NN clone rules

So if it was a coding competition I guess Ankan wins if either Lc0 or Allie win? Yep. (Which underlines that TCEC can't possibly be that - he's playing against himself) Or maybe *you* should get some credit if either win? Even better: I'll win TCEC if either lc0, Allie, Stockfish or Stoofvlees wins...

Re: Back To The Beginning

I have plans to build a new Intel box pretty soon, it seems that Intel will have a very big price cut on their new HEDT CPU's (Cascade Lake X) next month. If this is really true and they will sell the new 28 core for a price of about $1700 I will certainly buy one. I've been thinking about AMD, but...

Re: Some speed tests with Leela and Allie

Node speeds reported by lc0 based engines are nonsense because cache hits are counted as full nodes. Likewise, the reported depth for MCTS-based engines is arbitrary.

You can't conclude anything from these numbers.
