Following the double I rolled 4-4, which made the cube look terrific! Then next turn got to this position. Will you leave one blot or two?

The story so far, see Bundalongadorbel, the thread that died of shame.
We left our hero playing the White Checkers and leading 2-0 to 13, on roll and contemplating a double in the position below. I doubled this in the match, but it's not strong enough to turn the cube yet. Although White leads in the race by 18 pips, has the better position and some attacking threats, he should wait. An advantage in position, race and threats is usually enough for a cube, so why not here? There just aren't enough market losers and White will usually be able to get a take next turn even if he rolls well. The problem is that there are not enough checkers in the zone, ie checkers bearing on the 4 and 3 pts. 8 aren't enough and even if the White checker on the 11pt moves up to the 9pt it's still not a cube. Ten checkers in the zone is ideal. What this tells us is that threats ( to radically improve next turn) are more important than race or position. Threats increase volatility, the key element in good doubling.

Doubling is a blunda and Red is delighted to get the cube on his side so early in the game.

They may be interesting positions, but I don't see much in the way of commentary except that of the author. I only can hope he doesn't get bruised patting himself on the back.

I have contributed what I consider to be thoughtful commentaries on many occasions which have often been greeted by vacuous criticism, some of it your own. I don't recall you ever inserting yourself to chastise any of my critics.

No harm, no foul, or, in the words of a former client, NEVER EXPLAIN, NEVER COMPLAIN.

BTW, if I had referred to dorbel as DIMBELL or DORKBEL, no doubt you would have censored that. I guess you feel that only you can use derogatory names without fear of censorship. It's a cheap shot which in my opinion demonstrates your own brand of hypocrisy and is unworthy of anyone claiming to be an impartial moderator of debate and discussion.

This thread is like the sound of one hand clapping.

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.
