For what that's worth, Stockfish 11 gives Rh2 as +2.6 Kb4 as +2.2 Bxc7 as +0.6 other moves as 0.0 on my machine at depth 45 (will be updating this answer while it digs deeper). Rh2 and Kb4 occasionally switch positions as #1 and #2, so it's still unclear which one of these is truly best. Bxc7 surely isn't, however, at least if you believe Stockfish. One ...

Houdini is severely weaker than LC0. I have seen their evaulations of positions, such as in the Salvio Gambit, which Houdini evaluates as only slightly worse for White(clearly not true), where LC0 states that Black has a sizeable advantage. Thus, it is more likely that Leela had played the best move. We cannot know for sure until we prove a forced win for ...

If you set the contempt factor really high in an engine that it will likely be able to play armageddon. Contempt factor is how much it accepts (or doesn't accept) draws. If contempt is high enough it should view a draw just as bad as losing. https://www.chessprogramming.org/Contempt_Factor is a good article to read on contempt factor if you're unaware of the ...

It's likely a draw. After going through a few lines (which strengthens the transposition table), Stockfish 11 at around depth 42 gave me 0.74 in the starting position. Especially in such a simplified endgame, this shouldn't be enough for White to claim a win. I also set it to White to move in the starting position. Some variations I analyzed with Stockfish: ...

Stockfish on depth-22 states that the position is +1.41 for White. However, eventually if Black gets rid of every pawn but the h-pawn, it's a wrong rook pawn draw.

Well i usually play with stockfish on my mobile to sharpen my chess skills. I am now good at chess playing. My opening (as far as I think) is one of the best in the world. I never played officaly against any grandmaster but informally i have played against a state level champion (Bihar, India) i beat him easily in both the games (on a train journey). I tried ...

What this means is that if you assume every test has some noise, if you only look at the tests that turned out well, some of the reason they turned out well was likely that noise was in their favor. As such, you expect regression to the mean if you were to re-test only the passing patches. They would appear less good, because "passing test" is a ...

Dunno but BxP on c7 looks like a winner to me. Whether black captures with the rook or not the b pawn marches quickly to become a Q

If that wasn't enough White's rooks are very mobile and can attack down the d or e files, potentially doubled, or supported by the queen.

White has a protected passed pawn on c5, which means almost all endgames will favour White. The d4 square is also a great spot for the white knight (indeed the engine suggests Ne2 preparing for that) If Black has to give away his g7 bishop, then the king could be in trouble due to the weaknesses of the dark squares around it. And things aren't much better if ...

Using the Dorfman method to evaluate the position, White is statically much better, and probably close to victory (which may explain the +2.3). Both kings are safe and the material is balanced. However: The d4-square is a fantastic outpost for the knight, which it can reach easily via e2. The pawn in d5 is isolated and weak. Its advance will be prevented by ...

Here's my theory for this position. The engine is evaluating +2 advantage because black's rook can be trapped. First, watch carefully, that rook on h5 is isolated from the main game and has only another safe square to move (i.e, f5), where it can be backed by Queen (on e6), as well as the pawn on g6. So it is dubious to exchange white queen for a rook. So ...

leela or alpha zero is the best computer it beat stockfish in normal chess and leela is said to be better at positional chess then stockfish and stockfish is better at taktical chess and since chess960 is more positional chess leela is the best computer in chess960.
