Re: Leela crushes any resistance in this position

Tried a couple of games in 30m+30s format with contempt at 0 and 36 (+50% in contempt) both ended in draw. Strangely SF does not treat the bishop as a problem. What do you mean by "does not treat the bishop as a problem"? I'm pretty sure this is a draw. If you were sure you could produce a defense ...

Re: Leela crushes any resistance in this position

I should have written "products", not "results". It's useful data but not definitive.

It's better to have it than not to have it, so who here can be persuaded to play White? I'm pretty sure this is a draw.

Re: Leela crushes any resistance in this position

It's not necessarily a won position, as long white play precisely, it may turn out that white can hold. Leela selfplay ended in a quick draw. And SF Dev with -30 surprisingly held against Leela. It seems that negative contempt is required for SF to be able to hold. <snip> bxc6 {2.41/14 91s} 16. h5 ...

Re: Leela crushes any resistance in this position

Nope. A skilled centaur will have the same performance. Respectable machines are for those that haven't figured out how to analyze with their engines. My point is that we can always organize CC games (the results of which you severely over-value but are still of some value as data), but I (for exam...

Re: Leela crushes any resistance in this position

I don't think it's enough for Black to play accurately. White has also to play inaccurately for Black to win. Then we can ask how can white address the problem bishop on h2 without compromising the stability of the position. In order for white to being able to hold, it has to be addressed. Otherwis...

Re: Leela crushes any resistance in this position

Too bad nothing is at stake because no actual game is being played, so the truth will never be known. The truth will certainly not be known merely through playing a game, but we can arrange a CC game if there's the will. We do need someone with a respectable machine to help with White, though. It's...

Re: Leela crushes any resistance in this position

Is all hope gone for white here ? r4rk1/pp6/1bn1R2p/6pb/5p2/1NP2N1P/PP3PPB/3R2K1 b - - 0 6 Umm... you've posted this position before, right? It looks very much like a draw. (i.e. the analysis from last time, not the first impression.) Sure, White has to grovel but he gets the draw with accurate pla...
