“I have the Guanzi Pu pdf (‘New on the AGA Website: Classic Chinese Problem Collection‘ 3/16 EJ) in other formats already, but this one is very nicely done,” writes Michael Redmond 9P. “That collection is one of the best of what I call classic tsumego collections, but on the other hand, it wasn’t all problems that would now be called tsumego. It includes many endgame sequences, and some positions in which there is more than one feasible way to play. That is typical of the ancient Chinese collections, which were published before the modern definition of tsumego was established. From the professional viewpoint, those indefinite problems actually add value, although they could confuse weaker players.”
