Comment:
Quite complex position. Hero plays Gammon Save position, full-prime vs 5-prime. The rule of thumb says "favourite is the player, whose prime will last longer". In this case, the splitting of back checkers is crucial, we will probably dance for a while after beeing hit, and opponent's prime (potentialy full prime) will have time to collapse. Hitting opponent's blot is counterproductive, however it is the only sane move.
