ROLLOUT

In Response To: quacks (Petter Bengtsson)

My opponent cleared the 8-point in this position. I can see myself making the same play since clearing your last outfield point is usually a good thing to do. But it's a big mistake (see first rollout).

The lesson to be learned is that it's important to have spares on the 5-point versus the 3-1 backgame. The clearing play does a lot better with a spare on the 5-point (see second rollout).

The score is: petter 2, opponent 0 (match to 7 points)
