Overview
Its a Moneygame and White on Roll, Cube is centered, so both Players have access to it. White has the Racelead, and we are in Prime Battle. White has already a 4-prime, Black a 3 Prime. Important is that Black has an Advanced Anchor on the 4 Point, which is also at the Edge of the Prime. White cant extend his Prime because of this Anchor. The Gameplan for White is quite easy, bringing his Blots around and winning the Race. Black on the other side has also the Prime plan but he also has the possibilty of Attacking, cause White doesnt have an Anchor.
It should be crystal clear that the best 6 is to hit with 24/18*.

24/18* 17/13

After 17/13 Black has some nice Counter Rolls with hits: 1-1, 2-1, 3-1, 1-4, 1-6,  2-2, 2-4, 2-6, 3-3, 3-4, 3-6, 4-4, 4-6 : all these Rolls hits one of the 3 Blots of White and leaving 2 Blots exposed for Black to Attack 22 Rolls. If thinks works bad for White he could be Attacked or Blitzed very fast.

Let´s count the Rehits after 18/14 : 1-1,1-2, 1-4, 1-5, 2-2, 2-3, 2-4, 2-5, 3-5, 4-4, 4-5 thats only 19 good Rehit Rolls for Black. 3-3 is also a Rehit, but Black would loose his 5 Point. The less amount of Reshoots for Black makes this move to the best. This Problem is easy to solve if you give yourself Time to count the Rolls.
