Re: Komodo 13.1 Android strange mcts bug?

It's an interesting challenge for MCTS because whatever move you try it will end in a win when you play it out so there is nothing to go by when choosing moves. I think the solution is not obvious but it seems that either counting distance to mate (if you play it out to the end) or using additional ...

Re: Can current top engines still be beaten?

Assuming chess is already softly solved for practical purposes (you can draw with black assuming you have enough resources and time for a move within reasonable realms for both) it seems to me the most interesting project is to find ways which are objectively the best tries to win. There is a concep...

Re: Can current top engines still be beaten?

I've taken a look at the recent World Championship: https://www.iccf.com/event?id=66745 All decisive games resulted from wild gambles by black in the opening, The winner got a huge gift when someone played Mar Del Plata King's Indian vs him (very likely losing opening imo and certainly one you are d...

Re: Can current top engines still be beaten?

The wall doesn't exist, if it did every correspondence chess player could make use of it when they're black and avoid losing. That's exactly what the are doing and that's why all the games among good correspondence players end in a draw unless someone feels adventurous. The reason not every corr pl...

Re: Can current top engines still be beaten?

Can't edit anymore but recent example is AlphaZero vs Stockfish match. They had competent chess programmers with a lot of experience in engine testing and programming on the team. They knew opening book is supposed to be provided for SF for a match to be fair and the only reason official SF doesn't ...

Re: Can current top engines still be beaten?

the rule of ELO per doubling doesn't break Not sure about that. All the engine matches are played using opening books to ensure variety and interesting positions. I am talking about "build the wall" approach with black and the wall building is quite well analyzed by now with literally thousands of ...

Can current top engines still be beaten?

I don't have experience playing correspondence or very long time controls engine assisted matches. I do a lot of opening analysis and while I believe there is edge for white everywhere in human terms it all end up in endgames which should be easy to hold for engines. I would love to get some perspec...

Re: 1.g4 opening is losing?

Yeah, suppose 1.g4 is actually a draw, and you play a self-play match and get that 73% of games are indeed won. What you'll find is that in those games white played losing moves that it didn't play in the other 27%, so you create an opening book and forbid the engine to play those losing moves. Wha...

Re: 1.g4 opening is losing?

Newest T60 Leela network gives eval of -73% for after 1 Million node search (a bit over a minute on 2080ti). If 1.g4 is losing it's interesting to ponder if openings like Benoni or Mar del Plata King's Indian variation are losing as well. If you play around a bit you get around 65% for white in thos...
