Match play. 1-1 to 5. How should Red play 43?
There are several plays that are very close to each other in terms of equity.
It is not clear how this position will develop so it is best to avoid plays that are too committal.
The two plays to avoid are 14/10, 13/10 which gives up the mid-point prematurely, and 22/18, 21/18 which gives up the security of the anchor far too early.
14/7 is technically the best play but 22/18, 14/11 and 14/10, 8/5 are both fine. Any play other than these three is either an error or worse.
