Direct builders. All the work we can do is build a new point. Ideally on the 2 or 3. So that if we hit to contain him with a 5 point board. A point on the 9,8 or 7 seems out of time as the ace is made and all it can do is produce a 4 prime for a very short time - we would like to use these 3 free checkers to build on the 2 or 3. Now, the 5 is mandatory 13/8. We said we do not need the 8 point so 13/12 remains. Wrong! If we need to make the 2 or 3 point the best way do to so is to play 13/8, 9/8! Not be cause we need the 4 prime, but because we create 4 direct shots (building steps) towards building the 3 and 2 point, instead of 3 shots. Namely 8/2 and 8/3 two times! In addition, if we hit next roll he has no returns and we still have a 4 prime... Beautiful.
