587.0. "GO problem, May 1986 American Go Journal" by REGINA::OSMAN (and silos to fill before I feep, and silos to fill before I feep) Thu Sep 25 1986 11:14

    Here's a Chinese go problem from the May 1986 American Go Journal.
    I consider it quite hard, because even if you find the right answer,
    you must check quite a few possible retorts to be sure.

    The text reads as follows:
    
    MORE PRECIOUS THAN GOLD
    
    B to live.  B may get an eye by playing either a or b, but there
    is not time to make a second eye.  They key is to use the two sacrifice
    stones, and to consider B's relationship to the corner.
