Red is running out of time and also playability.
For money 13/12, 13/8 is a reasonable play but at DMP where gammons don’t count and he has to create action now in the hope of taking advantage of his strong home board. Note also, that while the race is bad it is not yet completely lost.
The only realistic play is 24/18. Everything else is a bad error or worse. After 24/18 Red will win a quarter of the time which is the best he can hope for.
After 13/8, perhaps split the back checkers to maximise hitting potential. As for yesterday's solution, can you please review it, as obviously gammon losses are irrelevant for red?
