Re: What is the outcome of this unusual endgame
easily defended by modern engines on high end machines, keep in mind with minor piece endgames, the bishop side can sack both bishops on the last two pawns to secure the draw when going against knights ...the 1.5 CP advantage is an illusion...Nordlandia wrote: ↑Sun Nov 22, 2020 4:41 pm BB vs NNPP | +1.5 pawn edge for black.

Re: What is the outcome of this unusual endgame
Evaluation doesn't mean a thing. Engines can evaluate a dead-lost position as +8.5. You would have to play out the game.

Re: What is the outcome of this unusual endgame
Had a single game till now with LC0 for Black against Cfish with classical eval (cause I think that to be rather a matter of search but of eval). Both 6men Syzygys, LC0 was running on RTX 3080, Cfish on 24 threads of 12x3GHz Xeon X5670, 4G hash.

Re: What is the outcome of this unusual endgame
I am also finding this position is a win for black. Deep positional analysis shows this is a win for black. Now playing shootouts. The first game has blacking winning again with Stockfish 151120 playing the shootout. Next will be Dragon, then Lc0.peter wrote: ↑Mon Nov 23, 2020 9:56 pmHad a single game till now with LC0 for Black against Cfish with classical eval (cause I think that to be rather a matter of search but of eval).

Re: What is the outcome of this unusual endgame
I have not looked at this position with an engine. But I believe that at a glance, most strong players would evaluate this as winning for black. Black is up two pawns, and all four pawns are connected. It seems obviously winning.

Re: What is the outcome of this unusual endgame
Had then 4 more games, one LC0- Cfish again, the fish this time useing NNUE Hybrid with hardware- TC like the first one, two with Dragon for Black's side, one with SF dev, Cfish always having White.mwyoung wrote: ↑Tue Nov 24, 2020 1:34 amI am also finding this position is a win for black. Deep positional analysis shows this is a win for black. Now playing shootouts. The first game has blacking winning again with Stockfish 151120 playing the shootout. Next will be Dragon, then Lc0.peter wrote: ↑Mon Nov 23, 2020 9:56 pmHad a single game till now with LC0 for Black against Cfish with classical eval (cause I think that to be rather a matter of search but of eval). Both 6men Syzygys, LC0 was running on RTX 3080, Cfish on 24 threads of 12x3GHz Xeon X5670, 4G hash.

In the pure A-B-Engine- games each of them had 12 threads with 30"+5' to compensate the halving of the threads, Cfish lost all the games as well with classical as with hybrid- eval, all games were about as long as the first one, longest game went 35 moves with GUI set to late give- up instead of early like in first one.
