This hand history is only to illustrate my question, not interested in analysis.
I belive this is a simple question, so hopefully somone has a simple answer for real time thinking.

Assume that his range pf is: TT+ AKs AKo and AQs
assume he bets entire range on flop. 2/1 dog vs that range
now if he only bets TT+ and AKs/AQs with the flush draw. 6.5/1 vs that range.
so now if we assume we are either a 2/1 dog or a 6.5/1 dog how do we combine those stats, and average them appropriatley based on the percentage of time he will mathematically have the flush draw hands............
