This game simply shows a resignation error. Although both played ideally, the Top Player resigned prematurely even if their equity is not beyond -1. You can compute the exact equity by subtracting the equity of the best move in the computer analysis from -1. You can also see it in the game’s rating tables.

Bottom Checker Bottom Player wins a single game (1 point) and the match.
