Money Play. Should Red double? If doubled, should White take?
The race is equal, the home boards are equal but White has a checker on the bar and therefore Red has the advantage. The position is very volatile and so Red must double now to activate his gammons and to avoid losing his market.
However, he has a lot of work to do to complete the win and meanwhile White is a slight favourite to enter next turn (unless Red rolls 33, 44, 66, or 63).
All of this adds up to a clear double but also to a very easy take. Dropping would be a triple blunder.
