1.g4 opening is losing?

[Ovyron]

Do you feel ready now for a re-match CC game with Ovyron?

I think we should wait for the equivalent of contempt for SF NNUE or something else to prevent shuffling before trying this. But it would be fun to do another one

I'm up whenever you want , after NNUE (being able to analyze interactively with NNUE or Classical Eval) I estimate that my level is the one I'd have with Stockfish 11 and a 16core machine, so I didn't need to upgrade my hardware after all

I'm willing to play draw odds, if you draw with 1.g4, it's 1-0.

[Alayan]

CDBCN reached -152cp after 1.g4 d5. The DB doesn't allow to easily find how many positions are present in this position's subtree, but it has kept on expanding and no good defense for white has stuck.

This doesn't exclude the possibility of one extremely precise line that would draw but gets too incorrectly evaluated early on to be expanded enough, but it behaves very much like a lost position.

[Uri Blass]

Something unusual: the eval was -1.26 from depth 21 to depth 82 and it took just 34 minutes to get there. But now it's been searching depth 83 for a very long time:

Just to update I gave up on waiting after a couple of days but I will re-evaluate once there is a newer version of SF that behaves differently here.

It seems that there is a version of SF that behaves differently and I wonder if there is a better conclusion about 1.g4

It's impossible to prove, but I think it is likely that 1.g4 is losing. Current Komodo Dragon with a deep search gives it a slightly worse score than it gives to White with b2, c2, d2, or e2 removed, all of which are most likely losing for White, based on both general chess wisdom and on actual playouts by top engines. We haven't reached the point where we can answer questions like this definitively by analysis, we can only play them out at high level many times and go by whether the losing side holds half the time or not.

Stockfish didn't lose to Dragon either. Maybe there's a fine line to salvage. 4cpu, 90+30.
