Sure, maybe. But can you quantify that at all?

For example, let's atart with the assumption the the opponent flopped a set of QQ. He open-checked both the flop and the turn. Obviously he doesn't want to "lose customers."

NMow let's give that same guy AA and flop him an overpair. Does he still not want to lose customers? What if we give him AK and flop TPTK?

Of the later 2 cases (AA and AK), I think it's less likely that AK will be afraid of losing custommers, but it's still quite possible. How possible? 50%? Less/more?

Whatever value you come up with, you can simply multiply that by the 16 ways he can have AK, and you can use that adjusted value to compute the EV of your varoius lines.
