Money play. How should Red play 33?
It is easy to get seduced by 13/1, making another home board point but far, far stronger is 13/7(2) making a five-and-a-half-point prime with White’s two checkers on Red’s 2-pt well and truly stranded.
What perhaps is surprising is that any play other than 13/7(2) is actually a quintuple blunder or worse!
