In Response To: Rollout below (Mislav Radica)

If the 3 is 8/5 how is the better ace 24/23 over 6/5 in this position but in the WSOB 5 it is a significant error to split over smoothing?

The score (after 1 game) is: Robert Koca (US) 1, Jakob H. Simonsen (DK) 0 (match to 3 points)

Move number 3: Robert Koca (US) to play 16

Robert Koca (US)164
