Title: Game 1, move 19: Herd to move 4-2
Post by: diane on August 10, 2010, 09:37:20 AM
A few 'next' moves took place after r_monk moved,

Herd:4-6, 6/off, 6/2
r_monk: 6-2, 24/16
Herd: 2-4, 5/1*, 3/1
r_monk: 4-4

Now herd has a few choices with how to play this for the best.

4/off 2/off should win most gammons, and it's still pretty safe overall, so I don't see a need not to rip 2 off. OINK!

I like playing safe with this one and go with the 5/3, 5/1 play.  I've been caught too many times with a 6/1 roll on the next roll which could put us in jeopardy for the next roll after that.   :ohmy:
