Daily Chess Puzzle

Today’s problem is from an old edition of Chess magazine; not sure which, I had photocopied the “hard” puzzles page, and used it as something to pass the time when dog walking or walking in the hills.

As is my custom, I only say which side is to play: and not giving an idea if the move wins or otherwise, unless on occasion I think signposting would be helpful. Instead, the problems are posed with the instruction to decide what you would play, as in a game.
