Why is, according to Stockfish (depth = 28), Kh8 the best move here for black?
This is a position from a game between Emanuel Lasker and Wilhelm Steinitz, 1896.
Nb6 seems to be the natural move in this position. At least to me (an intermediate player).
Yes, there is a check at Qb3 or Bc4. But what's the big deal? The b7 pawn is protected if Nb6 is played. Bc4 is also not an option then.
It's not a machine-like move. Steinitz played this, not in this move, but in the next move. Kh8 is not even among my [an intermediate player :-( ] candidate moves.
This is the first time I am posting in stack exchange. Please excuse the bad formatting of the question. I don't know how to add PGN here so that you guys can go through the game move by move.
