Re: Karjakin 17.Bxd5 !

I think it was a practical choice for a human to play again another human, but I doubt any strong engine would have problems with that exchange sacrifice. Caruana had to play some inferior moves to get in a lost position ... something a good engine would not have done. That is why you will have a ha...

Re: Announcing lczero

https://github.com/glinscott/leela-chess It's a port of GCP's Leela Zero (https://github.com/gcp/leela-zero) to chess. GCP and the community have really done a wonderful job on the project. The goal of the project is a distributed training project for the network weights, hopefully building a stron...

Re: Chess World to Google Deep Mind..Prove You beat Stockfis

Reviewing the drawn games would be useful, and presumably there is no obstacle to theAlphaZero team making these available on-line. Ofc that there is an obstacle. A0 has zero variability in search or evaluation. The only variability there comes on 8 threads waiting in the queue of each TPU for eval...

Re: AlphaZero Chess is not that strong ...

The biggest proof that A0 is very strong is in the move choices that other engines seem to think are not good, but turn out to be very deep. Remember that SF is an extremely fine tuned engine while A0 is in the infancy stage and most likely will get much stronger. It would be nice to have an Open ma...

Re: David Silver (Deepmind) inaccuracies

The idea of using several GPU cards to run very fast real time MC games has always been an interesting idea. With billions of lines tested you are bound to hit a promising but obscure line which the brute force of CPU powered SF can quickly verify it is a good line. Hopefully this is something some...

Re: David Silver (Deepmind) inaccuracies

I really don't understand why all the hate for A0. Clearly they chose SF because SF is considered the strongest chess engine. Nothing wrong with that assumption and while it might not have been TCEC champion, nothing I have seen changes the fact that we all know that SF is one of the strongest if no...

Re: Stockfish 9 ASIC

Surely FPGA would be a much better idea. ASIC cannot be updated and for sure SF would need continuous tuning. Also the number of units that would be produced would be very few, thus would make no commercial sense to go ASIC. FPGA has been used in chess engines before and maybe A0 will make this plat...

Re: The Alpha Effect

Very interesting! This actually makes a ton of sense for the opening. What would also be great would be to implement something that allows massive amounts of Monte Carlo lines to be tried in real time via a GPU card that better prunes which lines an engine should search deep. This would be a force m...

Re: Much weaker than Stockfish

Some of the games are really remarkable. I think a PC can be configured to play in a similar fashion. Maybe massive GPU floating point calculations can actually work for chess ... just needs a different approach. I always thought that a chess engine that can use a Monte Carlo based GPU as a partner ...

Re: Houdini with a six point lead near the halfway point of

I agree you have to accept a mistake and deal with it till next TCEC. It is a shame to not have the best version though. 23% is quite a big difference if both engines are very close in strength. It did seem that Houdini was seeing a little deeper in positions. But have to give credit to Houdini team...
