So, White to play 3-2. The temptation is to split at the back, working towards securing a high anchor, but 13/10, 13/11 is best by a very small margin. Because Red has made her 2pt, it's going to be very hard for her to make a containing blockade. The 2pt and the 8pt can't be part of the same prime, so no hurry for White to split. Splitting actually plays into Red's hands, as it gives her targets to attack and blitz, where her 2pt will be useful.
I played 24/21, 13/11, but that isn't even the best split, as it moves to a point that Red would prefer as a target. 24/22, 13/10 is the best split. The match play is a small mistake, -0.028ppg.
The rest of game 2 proceeded along uninteresting lines and I eventually cashed to lead 2-0 to 13.
In game 3 we arrived at the position below, White on roll and contemplating a cube. What's the correct cube action for both sides here?
