I used Robertie Rule (5-1 for us; 4-3 for Kit) and felt the resulting
position was near borderline.

> What's Robertie's Rule?

Give yourself an above average roll (but not your best). Then give your
opponent a below average roll (but not his/her worst). If the resulting
position is still a Take, then don't double, otherwise double.
