Hit loose is still no option to me, I'm only 5 pips behind: that isn't very good but it's still better to play safe than to take an enormous risk. I have no board at all and you are close to making the 4-point.
So I'm still forced to make not-very-goodlooking choices.
I can't leave a direct shot, that would give you the opportunity to hit and make the 4-point.
Leaving an indirect shot gives me a direct shot when you hit. But again my board is awful.
I like making the 11-point, but I have to play 8/3 or 6/1 then to avoid a direct hit. I don't like 11/6 8/6. Think I like 13/6 best, but I'm in doubt... maybe it's still too risky. Or maybe I just danced too much last days.
Hmm, I think I play it anyway. 13/6
about that loose hit....rollout:
Spoiler
gnubg 0-ply rollout doesn't like the loose hit, but it likes it better than 13/6. it's choice is to make the eleven point and then play the 5 behind our runner.
