Bar-20, 6-3 if it were me...but factotum rarely does that, so lets see  ;)

never seen factotum do a "i am diane", no  :mellow:

B/20 7/4* I think, it's risky, but factotum can't just leave us alone. He has the perfect anchor for safety, he's behind in the race and we're about to escape our backman whereas factotum has two backmen. That all points to a bold play. The matchscore means factotum's gammons count while ours don't, which is an additional factor to play a bit more bold.

Whenever I have a tough decision to make in life, I ask myself 'What would Diane do?' It would be cruel of me to say whether I follow the advice, or go against it, but that's unimportant. That being said, I *shudder* agree with her here. I'd be patient and wait for something to open up, rather than force the issue, but that's factotum's decision to make. I wonder if he asks himself the Diane question, as well.
