White to play and win

Solution

A calculation exercise: not easy, not hard. The first move is obvious, and then it is a question of defeating each of black's defences, with the move played in the game the one which provides most resistance: but it is fairly straightforward calculating if not to the end, then as far as necessary: i.e. to a position where white clearly has plenty and probably overwhelming advantage.
