Cash game. White to play 3-1.

 

Note: All ‘cash game’ problems assume the Jacoby Rule is in effect. That is, you can’t win a gammon unless the cube has been turned.

This position shows the tail end of a long prime versus prime struggle. It was an unusual game in that both sides had a lot of men back. The primes have advanced about as far as they can, and now each side is starting to face cracking danger.

White’s 3-1 roll presents him with a choice: he can play safe for now, with either 6/3 4/3 or 6/3 5/4, or he can slot the 2-point with 6/2 or 5/2 4/3, leaving a blot but giving himself a much better chance to still have a 4-point prime (or even a 5-point prime) next turn. What’s the right plan?
