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?

White should indeed double from the bar, even entering without hitting is a market loser if Black dances and for Black, this is a very big pass. Black actually wins this about one game in 3, but loses a huge 43% gammons. In the match I cashed and led 1-0 to 13.
Boards too dark and hard to see? Here's a new one.
In game two, Red rolled 6-4 and made her 2pt. Once upon a time this was the play that marked you as a fish, but times have changed and this is now correct at gammongo and other scores where the player trails. How should White respond with his 3-2?

White has a far better board and easy out so I would go with a cube.

The right answer for yesterday is actually double/pass, with playing on having an equity of .982 compared to the equity of 1.0 for cashing. The question of whether to cash this sort of position or play on is always hard to answer. If I'm not sure I usually double anyway, putting a point on the score sheet that I don't have to earn with good play, but I guessed that this was much too good, wrongly. This is a reference position if you like to keep them, one where the equity is almost the same regardless of what you do.
Things went well for a while, but then Black managed to hit back during a fight for White's 5pt. With both sides having a man on the bar, what is the right cube action here?

Yesterday's position looks as if there isn't much happening, but it does illustrate an important theme. It's important for White to get he blot on his 24pt into play, so that he can hit from there (if he gets the chance) without breaking his anchor. So 24/20 is the important bit and then you can choose a three. I selected the second best play, 11/8, but it doesn't apply much pressure and 6/3* is correct. My play is right at gammonsave, which implies that I am not playing aggressively enough. "When in doubt, hit" remains one of bg's enduring guidelines.

Later in the game, we got to this next position, where White has to think about cubing. It's a monster pass of course, but is it too good? We'll see tomorrow.
