At that score White's takepoint is 20% and gammons are worth 0. Black's gammons are worth 1. Black's winning chances must be in the mid 50's here and his gammons higher than the initial 15%, so I'd say double. Assuming Black's winning chances are less than 60% his gammon chances would have to be greater than 20% for White to drop and there is no way his gammons exceed 20% here, so D/T. That's my dumas analysis.
