Bishop's Opening

Black's KKt attacked White's Q+KP - a fatal error.
White's KR5(h5) Queen takes Black's KBP - a game won in 4 moves! Novices should learn the principle of this combined mating attack upon an opponent's KB2(f2/f7) (his weakest point until castling) - and how to avoid it - useful in many situations.
