Re: A position some have claimed will never be solved ...

I think Lc0 might be able to get this mate easily. Already seen similar endgames, where Lc0 trapped SF king while having material disadvantage but still won It sucks at it. It thinks black is winning (95%) although it does show 1.Ba6 as a top choice :) 8 [+4.72] 1.Ba6 Bfd4 2.Kxh1 B4e3 3.Bc8 Bdb6 4....

Re: Long analysis of some opening positions

For example, you wrote, "Leela finds refutations to 11.Qa4 and 11.Qf5..." What refutations? Where are they? Are you claiming that 11 Qa4 and 11 Qa5 have been refuted? Or do you mean the opposite, that those two moves refute Black? The confusion is compounded with "...they are completely dead". What...

Long analysis of some opening positions

I am making this thread to dump long analysis of some opening positions I run. Maybe it's of some interest to practical players here. It might be fun to see if engines of the future change some assessments. No promises to post often but for now I am dumping a lot of those to my notes and I thought w...

Re: Dragon vs GM Nakamura Analog Handicap Match

I thought Hikaru has a decent shot but after seeing those Dragon vs Lc0 CPU games I now have doubts. There is a a huge difference between pawns and N handicap btw. Winning N up just requires some practice, I am convinced any 2200+ player could learn it in a few days. 2 pawns is a great handicap. I w...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

Here is the bottom line. Draw rate is not a indication of perfect chess play! :roll: You assume too much. I just want to point out that you are the one who assumes the most. What is claimed more or less is that chess might already be solved (or in case of specific weak claim in this thread that it'...

Re: How close can we come to proving that white draws?

Finding a proof seems pretty hopeless to me. We just don't have any math tools suited for this kind of task. We are left with a situation where engines will get strong enough to guarantee a draw but it's going to be impossible to prove they are 100% correct. I would start with something simpler than...

Re: Perfect chess engine elo ( 32 men TB) can be within 200 of Stocfish in Tcec LTC conditions

Strawman! Only God and a 32 man table base knows if chess is a draw or a win for white or black in chess. If oneside is a win, a 32 man tablebase would lose playing the losing side without a single blunder against another 32 man TB from the winning side. And chess engines and humans are not good en...
