Daily chess puzzle

Today’s problem is from 38 years ago, when I was at Cambridge University. I have been visiting my alma mater this week.

As has been my custom on this blog for a while, I adopt the style of only saying 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.
