 Red's initial stones resemble [[Edge template IV2d]], but in Y it's not an edge template since there are multiple edges to worry about. With 1. b3, Blue connects to either the top or the bottom-left edge (but Red may decide which one). After Red 2. c4, Blue 3. b4! is the only winning move. The carrier of Blue's win is shaded below; Blue can play a pairing strategy where if Red plays in a cell with a letter, Blue plays the other cell with the same letter.

 If Blue 1. b4, then Red 2. c4! is the unique winning reply. This is similar to Puzzle 4, where the intrusion into the pattern resembling [[Edge template IV2d]] is the only winning move.
