user-1: I know that you can mate with two bishops, but I do not know whether it is possible if White has 3 bishops, and Black has 1 bishop. Is there a general method? If so, is it possible for White to checkmate in all cases, where he has n+2 bishops and Black has n bishops?

user-1: White must have two bishops of one colour and a bishop of the other to get checkmate. White can then attempt to pin Black's lone bishop, which is. easier as more pieces get on the board. Then, White can checkmate.
