Run, slot, or play safe?

I like the running play because if we are not hit we're in great shape, and if we are hit, we haven't lost much since his board is weak.  But although his board is weak, his blockade is strong and improving so we want to get out now before we're stuck behind it.

Playing to the 4 point is safe, but prematurely burries a checker.  I doubt it's all that bad (and for all I know it's better than running), but I want to get out of Dodge ASAP.

Besides, the Boss says so.

Agree. 24/15 for me too.

The vote's close, so I'm going to leave this for tomorrow morning.  Hopefully I won't wake up to a tie.

If there is a tie, the tiebreaker is number of individuals commenting with reasons supporting their decision.  So those of you supporting 13/4, tell us why you think it's better than running.

i like 13/4 as it develops our own board - he has none yet, so i would suggest that we can escape the lone chequer later...and remain a while to handicap his easy point and board formation. we also start to breakup our midpoint sausage - so to speak  B)

Problem with 13/4 is we don't make any progress, it's too passive. We invite Zorba to build his board or trap us inside. With 24/15 he won't have the opportunity to do that, because he has to react. If he can't hit, it will be really nice for us. If he can it's no big deal: he still has to focus on our blot, and he has to escape his 2 checkers too.
