24. Kg1 was disliked by LC0. I'll run my SF on the position after 24. Kg1 while waiting for your move.
Specifically, 24.Kg1 had a "relative depth" of 57, so if you get a < -2.30 score before then, then that'd point out to missing tablebases being the difference.

At depth 45 it already went down to -2.38. I kind of want to disable TBs now, my situation would look less awful ;)

(I thought you said you'd do that while waiting for my move, I already moved Nd7 and am waiting for yours.)

Heh, and nothing really would stop me from getting the full 6men TB set and use it, except for my laziness. I guess if I can't win this game and it's clear I'd have done so with the set, I'll go get it.

I'm glad we had these conversations, imagine if I get stuck waiting for your move for weeks :mrgreen:

At least we basically got to see how I'd have lost the game if I played 2.Bg2.

22.Bh3?? 0-1

Oh, I didn't see your link.

My PV line has 24.Kg1 instead:

22.Bh3 Bxh3+ 23.Rxh3 Nd7 24.Kg1 Bxg5 25.hxg5 Qxg5+ 26.Kh1 Ne7 27.Qe2 g6 28.Rg1 Qf6 29.Rxh5 Nf5 30.Rh2 Kg7 31.Qf2 Qe7 32.Nc3 Nf6 33.Nd1 Rh8 34.Rgg2 a5 35.Kg1 Rh5 36.Kf1 Re8 37.Rxh5 Nxh5 38.Rg4 Rh8 39.Ke2 a4 40.Kd2 axb3 (relative depth 61 - 5men TB Stockfish)
24. Kg1 was disliked by LC0. I'll run my SF on the position after 24. Kg1 while waiting for your move.
And Komodo had 24. Qf5.

Ne6 interesting move! It's not like Leela's playing rope-a-dope, all hands on deck man the fort... More like fuck it, let's pretend we're winning wit this knight. Get SF worried.

Indeed, it's like white dares black to take that Knight, but black can't! I'll call it the immortal Knight!
