I agree with Kevin. Timeout and resign should be worth 1xcube if the loser already has pieces off. I fail to see why timeout/resign should be penalized as there is no way more than 1x points could be lost even if the game had been played out.

But timing out or resigning before bearing off any pieces is a tricky situation because there could be a possibility that checkers can be sent back to bar. Maybe 2x points should be given after resign/timeout if all opposing pieces have passed each other and 3x otherwise.
