20/14(2), 13/7(2).  What was I thinking?  Attack a single checker, don't prime.   Especially with that blot hanging out there.

13/1*(2) should have been clear.

Later in the same game.  I am being doubled.  Take or Drop?

At least my gut thought this was a take, though I prefered to play with my opponent from two away rather than at Crawford.

The race is almost a take by itself, plus I have some contact left and the gammons are very low.  It all adds up to a thin money take.  Add in the lopsided score and the fact that I can recube aggressively and the take is very comfortable.

I instantly and rather lazily played 24/17, 4/1 aiming for maximum contact but all I really accomplish is getting myself gammoned more often. Oops.
