Match Play. 1-1 to 5. How should Red play 42?
“To kill or be killed?”, that is the question, to paraphrase the bard.
With gammons so important to both players White cannot be allowed his whole roll here so the banana split play bar/21, 3/1* is mandatory. Everything else is a double blunder or worse.
