2019 - Position 220
Money Play. Should Red double? If doubled, should White take?
A classic prime-vs-prime situation as and as we know, (nearly) all prime-vs-prime positions are doubles and takes. Red only wins 60% of the time but two-thirds of those wins are gammons and Red must double to activate gammons.
Not doubling is. 4.5 level blunder (-0.36 in terms of equity) while dropping is merely a 2.5 level blunder (-0.20).
As I said, all prime-versus-prime positions are doubles and takes!
