There is no valid human reason. The difference between Kc4 (mate in 12), and Kc2 (mate in 10) is fairly irrelevant. It simply appended the "?!" based on the algorithm that 10 is slightly worse than 12. Either way, it is, indeed, a simple win from there. By the way, my plan would be Rd7, then bring the king to h1/g1, and only then, bring the rook over via ...

You cannot get a definitive answer, but in all likelihood, 99.99% it is a draw no matter who is to move (I am the type of person, who never says I am positive unless there is 100% proof, and that is impossible here, however likely). The overwhelming factor in this position is that the black bishop does not control the a1 square, so even if white had no ...

Yes this should be drawn because: White has pawns only on one side of the board, and thus cannot overload the bishop (which can sometimes be achieved if you have pawns on both flanks). Black king is well positioned to blockade the pawn advance, and in particular preventing the white king to get to c5 and cover the two connected passers. b5 will always we ...

First, despite the big eval, it is still probably equal in the long run with best play. In the games below, the weaker side often weakened the position, making easier for the stronger side to win. When in doubt, it is probably not a good idea to move pawns while defending. It is of note that Anand, and I am sure this is not accidental here, has the optimal ...

On Lichess, inaccuracies are denoted ?!, mistakes by ? and blunders by ??. You can click on the `x inaccuracies/x mistakes/ x blunders' to move between these. The move was inaccurate since it reduced a forced mate from 16 moves (Kc3) to 13 moves. Lichess marks inaccuracies for large checkmate sequences, since humans aren't expected to find these.

Averbakh provides the following plan in an example with three pawns per side, i.e., no e-pawn. Use King and Rook to restrict the knights mobility Begin a pawn storm to cramp Black to the maximum extent Advance the King to the f7 pawn decides the game I doubt whether step 3 works with the e-pawn, but trying to win would look similar with the e-pawn. ...

Tablebases add only a little elo to computers. The amount added is small enough that for many years Andscacs was one of the strongest engines around without endgame tablebases (it still doesn't have them implemented). Even for other engines with tablebase support implemented I'm pretty sure you can not provide it with an endgame tablebase, and they'll play ...
