8.46 Two players, A and B, take turns placing chess pieces "Bishops" on the squares of a chessboard: A starts and places a white bishop each time, while B places a black bishop each time. Each time, the bishop must be placed on an empty square, either a white or a black square, but it must be ensured that the bishop cannot be captured by the opponent. The player who first cannot place a bishop according to the rules loses. Under the correct strategy, who will win? Explain your reasoning.
[Solution] B will win. Take the median line of the square chessboard as the axis of symmetry. B just needs to place his black bishop in the square that is axially symmetric to the square where A just placed his white bishop, and he will have a sure victory.
