In this great study from Ebersz, white can reach a draw, but only with extreme accurate play. The given variation is one possible. All white moves are forced, any other king move would lose. Suppose, white is in such a position in a practical game, of course without access to electronic topics. Can the correct squares be found out manually ? I know the theory of countersquares, but it seems to be extremely difficult.
How can white save this game without too much efforts ?
