- White to play and win (jigo is failure)
- No stones have been captured yet, komi is zero
- Works under both area or territory scoring
These examples come from the book “Mathematical Go: Chilling Gets the Last Point” by Elwyn Berlekamp and David Wolfe. The didactic purpose is to illustrate how quantifying the value of endgame moves must go beyond the typical real numbers. Instead, a very technical system is necessary to accurately and methodically work out exactly how to win the last point in the endgame. I don’t understand any of the details in the book, but it sure is fun and humbling to flip through and glimpse at how much I don’t know about Go.
