Second Proposition: King and Bishop or King and Knight against the bare King make a Drawn game.
Let us deliberate according to the above method. We soon find that a Checkmate with King and Bishop or King and Knight against King is impossible even when the weaker side has its King placed in the most unfavourable position, the corner. Should the aggressive King stand even in opposition to the cornered King, the besieged party will yet have one square of escape; should that be taken away by Bishop or Knight, the King in the corner will not be Checked and therefore a Stalemate will result; conversely, if the cornered King is Checked it is driven only on more favourable ground. The task of Checkmating with the above force is unsolvable.
