Casper gives a succinct explanation why slotting is wrong above: Also reduced number of spares on both 8 points: if you slot, your own covering 3s are weakened, if you split some of the point makers of your opp. reduce in value because they leave directly hittable blots. – 53P-21 –[S $4] –'^46 Compare this to the 2nd-roll position above. The 53P-21 rollout out was made by Alexandre Le Siege. Slotting fares better when there is a spare checker on the 8pt. In addition, after splitting, Blue can withstand an attack better when he owns his 4pt. Mike
