Re: Hard pawn endgame
Nice long zugzwang.
Current Stockfish has trouble with that.
The big difference between white and black is that white has the treat to create a winning passed pawn and go to promotion.
Surprisingly Sting-SF has a hard time here as well. No solution after 3 billions nodes.
But if you teach SF how to play, it recognizes immediately white is winning :
One possible line :
[pgn][White "w"] [Black "b"] [Result "1-0"] [FEN "8/5ppp/2p5/p1Pk1p2/3P1K1p/2Pp1P1P/1P4P1/8 w - - 0 1"] 1. Ke3 Kc4 2. Kd2 a4 3. Kc1 g5 4. Kd2 f4 5. Kc1 Kd5 6. Kd1 Kc4 7. Kd2 h6 8. Kc1 Kd5 9.

One idea to solve this kind of positions : if one side has a threat and the other side has only waiting moves, it's a bad sign.
So let's play all this waiting moves.

Re: Hard pawn endgame
no prob for Bluefish (Stockfish_19100908_x64_modern.exe did comparably well)...probably because of TB-using but i didnt test this:

Re: Hard pawn endgame
This is difficult. The best problems solver = Crystal is clueless after 10 minutes. It don't reach enough depth I think.

Re: Hard pawn endgame
What do mean by hard? All the engines find the correct continuation after only 1 ply. If you mean hard is to recognize a plus score for white, then Schooner2.1 with 4 cores finds a plus score in 38.51 seconds:Nordlandia wrote: ↑Tue Nov 05, 2019 10:34 am M.

Re: Hard pawn endgame
The first position is based on the theme moremovers associated with Otto Blathy. By hard i refer to moremovers such in the style of O.T Blathy.
Moremovers have been hard for engines to solve in the past.
For example:

Re: Hard pawn endgame
The first position is based on the theme moremovers associated with Otto Blathy. By hard i refer to moremovers such in the style of O.T Blathy.
Moremovers have been hard for engines to solve in the past.
For example:
[d]2K5/p1p4k/p1p5/2p3p1/6Pb/6p1/p5P1/B7 w - - 0 0
1k6/1P3ppp/P1p5/1pP5/p1p3p1/2P1K1P1/1P3P1P/8 w - - 0 1
