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.

Match Play. Red leads 5-4 to 7. How should Red play 42?
Kill or be killed? That is the question. Bar/21, 5/3 is the passive play but bar/21, 6/4* is the right play.
It swaps 22% gammon losses for 13% extra wins so despite the score and the fact that a gammon for White wins him the match it is still the right play. The passive play is an error but not a blunder.

Over the next few days the website will be undergoing a technology refresh and may not always be available so just try later if at first you don't succeed.

Match Play. Red leads 5-4 to 13. How should Red play 22?
Quite simply, if Red does not hit he must pass White’s double. After a passive play such as bar/23,24/22(2), 8/6 he is behind in race, threat and position and being behind in all three elements normally always indicates a pass.
After bar/23, 13/9*, the other 2 can be played 24/22 or 23/21. There is virtually no equity difference between the two plays. When in doubt, hit. That might just bring Red’s three-point home board into play.

Money Play. Should Red double? If doubled, should White take?
Over the board most would double and I would expect a fair few drops.
However, Red has five rolls that crack his 6-pt prime immediately and White can still build a prime against Red’s rear checkers. Technically this no double/take (actually nearly a blunder to double) but against all but the best I would try to steal a point in this position. Human beings err while XG does not!

Match Play. Double Match Point. How should Red play 21?
At DMP killing checkers is a crime to be avoided.
Over the board Red played 6/3 but that is a blunder. White’s board is irreparably broken and Red must maximise contact and hitting potential. The correct play is 8/5, starting the point that Red really wants to make.
