SF sees a mate!

Alright. Since you're not resigning that means you want the game to last as long as possible. I don't mind! From now on I'll demonstrate how all winning moves are equal, so it's the losing player who must decide if it's worth it to keep throwing resources into the game. Those people trying to find fastest mates are insane!

I'll purposely play really badly so the game lasts as much as you want, the kitten can play with its food!

He's playing on because, I suspect, JP didn't want him to resign too early. I think this game has had it's due. Time to move on IMHO.

Exactly.

Yeah, I think once you can see a mate with programs, it's enough. I resign.

Thanks for the game mmt! I was wishing for an opponent that would defend 1.g4 so that all my analysis wouldn't go to waste, so I was very happy when you appeared! I actually panicked secretly at the beginning of the game, because I couldn't find any win, and my advantage was growing slower than Harvey's advantage against me, but in the end >95% of the moves played themselves and I had no effect on them (I hold that if there was a drawing trap, I could have seen, and avoided it, but most of my analysis of alternative lines had no effect on the game.)

Thanks, good game! I learned quite a bit about LC0's and SF's evaluation and their blind spots. There were some very deep moves in this game that required perfect accuracy.

Yeah, I think once you can see a mate with programs, it's enough. I resign.

Thanks, guys. Can you please post the mate it sees?
That would be a fitting end to the game.
