Re: Syzygy tbs bug

it was 3-fold repetition... According to tablebases, the move played is correct (winning). So it seems that if an engine chose to play it (rather than another winning moves from tablebases), then the engine is buggy (unable to detect three-fold repetition). That or the GUI is buggy, and fails to se...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Now that zullil has opened to sharing a PV I'm willing to open the game again. All zullil would need to do is not discarding the PVs that are shown when he gets the score that he reports, to save them to show them at a later point in the game (when they don't transpose or when the game is over.) Ot...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Since both players have apparently completed their 17th moves, here is the initial portion of Stockfish's PV as it was when I terminated the search, after the game went dark:

14. Rxc5 Qd7 15. Qb3 Rad8 16. Rfc1 Rfe8 17. Qd3 Bxf3.

Re: Dylan Sharp Vs. Harvey Williamson (G4)

In any case, I'm sorry that my posts have bothered you. Had I realized that, I would have stopped upon request. Really? Have you forgotten my post where I requested you to stop? It's here: By the way, I don't understand your interest in tails of PVs or "precise" evaluations. Whatever Stockfish is l...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

It was only a matter of time before this contest imploded. :| It seems like they always do. (they = forum games) Huh? This is the very first time a game had to become private because of audience disruption. I've been playing correspondence chess games in forums since 2008 (as Vytron or Uly), and it...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

The game will continue by private message, we'll come back with the full PGN of the rest of the moves after the game ends.

Re: Dylan Sharp Vs. Harvey Williamson (G4)

OK, I've just entered Nxc5 Bxc5. Here's what my GUI shows after entering those moves. Of course, I've deleted the PV. -1.64 (depth 69, 0:00:28) So depth 69 takes less than 30 seconds, because Stockfish basically has the entire future game in hash---until some human surprises it. :wink: I hope that ...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

I want to thank Harvey for being a good sport. His move ordering and conditionals have been saving me a lot of time (for instance, all the analysis of 14...Re8 and 14...Rc8 that didn't need to be expanded after knowing he'll play 14...Qd7.) 1. g4 d5 2. g5 e5 3. d4 exd4 4. Nf3 c5 5. Bg2 Ne7 6. c3 dx...

Leela is something I can't emulate, so it'd be much more interesting to get its evals.
I could run both, but I only have 128 GB RAM total, and I've already given 64 GB to Stockfish.

I assume someone else can provide Lc0 evaluations.
