Mate In Two Moves.
In problem No. 2 the mating maneuver does not involve a special trick; the idea of the composer was merely to arrive at an extraordinary mating position, and he added considerably to the value of the problem by producing the same mating position in several variations. The key move is B-b3+. Black has three moves in reply. If K-e4, White mates by (2) Q-f2, K-d3; (3) Q-f3. If K- c6, the mate is accomplished by (2) B-b4, K-b5; (3) Q-b7; and if K-d6, White answers (2) B-c4, K-c6; (3) Q-c7 mate.

Mate In Three Moves.
A favorite trick with composers is to provide a stalemate which they relieve by obstructing the way of one of the pieces involved in the stalemate. The move which is thereby allowed Black's King exposes him to a discovered mate. The key move of problem No.3 is P-g8 (becomes Knight). After P-b5 Black is stalemate, but White relieves the stalemate by (2) Kt-e7, allowing Black to take the Knight on b4, and then mates by Kt-c6.
In trying to solve a problem it is a good method to examine Black's moves first. Often it will be found that whatever Black moves White can mate in reply so that all that is necessary is to find a first move for White, which leaves the position unchanged as far as the different mating threats are concerned. If Black has one or more moves at his disposal in reply to which there is no mate, the way is indicated in which to provide for these defenses.
