Presented here is the answer to the 3rd tsumego from Michael Redmond 9P’s coverage of the challenging tsumego problems featured at the 2016 pro pair go tournament.
The author of this tsumego is Kono Rin 9P. Michael explains what you may notice as a curious part of this position:
“White’s 2 non-attached stones do not change the problem’s result, but have the effect of pruning one of two correct variations for Black at move 5 of the answer, and another alternative answer later in the correct sequence, thus limiting Black to only one variation throughout the entire correct answer. In tsumego, there must be only one correct first move, but serious tsumego composers will avoid variations later in the answer as well.“
