If they find an interest in Chess for a try, then may resolve it and it might soon be the end of Computer Chess :lol:

Re: TalkChess Is Back

You know what else hasn't happened in a long time? A very popular Netflix show about chess being released shortly before the Black Friday shopping holiday (Which was Friday), at the same time as a pandemic causing yet another round of lockdowns. People are very interested about chess now and have n...

Re: TalkChess Is Back

Hello All, We all know that TalkChess was not working for a few days. But, why did it fail? Was it "hacked"? Why the redirection to "Off-the-air"? What protocol is now in place to ensure that doesn't recur? Thanks in advance, -Steve- According to Quentin, unexpectedly high demand for chess-related ...

I dont remeber people saying NNs on CPUs was going to happen.
maybe they were talking about MCTS, not about static evaluation
GPU run MCTS, CPU NN run alpha-beta minimax, but static evaluation is not handcrafted
OK. Interesting.

There are many different NN sizes and architectures.

The larger ones like Lc0 uses are only really practical on GPUs.

The smaller ones like SF-NNUE run on CPUs (and are very cleverly incrementally updated to make even faster).
Was it a mater of programing it to be clever?

Re: CPU NN question

I dont remeber people saying NNs on CPUs was going to happen. I dont know for sure. Does anyone have comments on NNs being used on CPUs ? It seems like its a big surprise. It seemed that only GPUs could do that. FYI I am an amateur hack on these questions. IMO Peter Osterlund's 2017 Texel/Giraffe e...
