Welcome to my blog of interesting backgammon positions.
These will be posted more or less daily and also tweeted. As I add a new position I will give a commentary for the previous one.
Please leave your comments.
Readers are invited to send in their own positions for possible inclusion in Position of the Day to Chris.

Money Play. How should Red play 41?
I got pinged by XG for playing 13/8. However, on rollout the difference between 13/8 and 8/3* is negligible. 8/3* both wins and loses more gammons.
So for money you can take your choice. Different match scores would significantly affect the play.

Money Play. How should Red play 31?
Red’s best hope is to outprime White even if that is relatively unlikely. Therefore, 5/2*/1 is the wrong plan.
The best play is 8/4, hoping to either make the point next time or get hit and stay on the bar long enough to preserve the home board. 5/1 without hitting is the second-best play. The 3-pt anchor will give Red long-term winning chances and he actually wins more than 25% of the time from here, although he loses quite a few gammons.

Match Play. Red leads 8-6 to 13. Should Red double? If doubled, should White take?
For money you can take or pass this double – your equity will be the same.
At the match score it becomes an easy take because of the power of the redouble to 4 by White. Four points will get him to the Crawford Game which is obviously very good for him.
I was White and took the double. My opponent’s next two rolls were 66 and 55 – c’est la vie!

Money Play. How should Red play 11?
The key here is to make the checkers work. Red needs his 4-pt so 6/4 seems obvious and carries very little risk. Then either 12/11, 2/1 or 2/1(2) are both OK with the other two aces.
Over the board 12/10, 6/5, 2/1 was tried but that is a surprisingly bad error. That 4-point needs to be slotted now.

Money Play. How should Red play 52?
Red should play with one blot so 13/11, 13/8 can be eliminated. !3/6 is also weak.
It is a choice between 24/17 and 24/22, 13/8. The latter gives free shots, i.e. very few return shots. Best is 24/22, 13/8 as if he is hit Red will nearly have a lot of return shots.
24/17 is a bad error but not a blunder.
