Mating with Knights and Bishops

The king must be restricted either by his own men or by the opposite king. Generally, either the knight guards one
or two escape squares while the bishop delivers mate, or the bishop blocks one escape square while the knight delivers mate and blocks another escape square.

 Mating on the Diagonal

Weaknesses on the long diagonal
lead to some interesting mates.

Bishops and Rooks work well
together here, but other minor
pieces can also be effective.
