  • White Plays and Wins

    I came across an interesting position this morning. Easy for a computer and EG table-bases have it solved already, but is it easy for a human?

    It is a study by Artur Mandler.

    Ken, thanks for the very nice study. Excellent example of using "long-range" opposition.
    It's not too easy.

      Therefore, what is the correct solution or solutions to this nice study?

          I think I would prefer to think of it as mined squares - nobody want to be the first to step onto c6,c7,c8 (black) or g6, g7, g8 (whilte). Hence, white's first move.
