I voted to run.  Not sure if it's correct.  My thought is that when it works (16/36 times) it nearly puts the game on ice for us.   And when it doesn't we still have a pretty good chance since stog has two checkers stuck behind our blockade and we'll only have one to extricate.

ah_clem, this only works 14/36times, but my vote and reasoning is the same as yours.

I suck at shot counting.  I missed the 65 to hit, so you are right 14/36.

Despite the fact that we got clobbered with the 65, running out to the 14 is best by a good margin.  Anything else is at least a double whopper.
