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...

Re: The “Kryptonite” position

It looks like possible problem in Leela search. At some point it realizes (quite quickly with Sergio net) that Kxh4 is losing but still lists it at the first option till visit counts catches up: 1. 13 [+0.00] 1.Kxh4 Kf4 2.g3+ Kf5 3.d6 Ne6 4.d7 Ng5 5.g4+ Kf4 6.d8=Q Nf3# 2. 13 [+53.30] 1.d6 Kxd6 2.Kxh...

Re: First knight odds match with IM Saturday

Hi Larry, thank you for answering. I don't have a good i7 as of now (will be purchasing big ThreadRipper soon though). I do have a very good GPU though. My ELO rating is low 23xx but I stopped playing many years ago during big raise. I am between 2500 and 2600 on Lichess blitz which is close to GM l...
