SF 11 found a mate in 84 after 1.5 hours on my computer. Depth 52. Then it went down to a mate in 28 and now it's down to 24 at depth 70 (2 hours).
Did it get any lower, Jim? And do you have SF's PV?

Can you post the games here?
Please, not while the game is ongoing!
Oh, yes. I think I didn't register that it's from the current position. Only once the game diverges from them.

Re: FGRL - 16 Cores rating list - 1. Lc0k 0.23.2 256x20-T40-1541

One day, Leela with a standard good graphic card will be stronger than Stockfish on any number of core. So it will be 500$ GPU >>>>> 20K $ CPU. Maybe. I don't know. I can't really predict such things. But this article suggests gamers disagree with you. The author is arguing it's not as bad as they ...

a valid Leela-Ratio of 1.0.
It's not "valid". It's "arbitrary" at best, and probably very heavily in favor of Leela by any reasonable measure. (e.g. if you follow crem's suggestion, you find it gives way too much hardware power to Leela.)

Re: 1.g4 opening is losing?

All you need to find is one good line and then back it up. Generally what happens is the opponents line will start changing trying to find better moves. Yes. But if your line is good there are few if any "better" moves. Even if it doesn't propagate all the way back to the root, let say it stops 3-m...

Re: 1.g4 opening is losing?

Okay, but I'm assuming we're thinking about a real CC analysis generally. No, we're talking about engines forgetting lines to mate, those only happen in won positions No, that is not true. The engine announces mate in a position you've gone to e.g. 40 plies down the line. (We assume this is correct...
