In general, it is necessary to have effective threats on both sides of the board in order to be able to win." The key here is the fact that White can place his K on a1 and the Black B is of the wrong color to promote his passed a-pawn so that, if necessary, White can trade his three Kingside pawns for two of Black's and sacrifice the B for the other Kingside pawn, even though he is a B and pawn up, can only draw.
