What if you raise the TAG and clear the field and then that TAG 3-bets you. How much do you like your hand on the turn when it blanks and TAG bet out?

Now, what about all those times that TAG is making this play with a flush draw putting you on AJ, AQ, AK, KQ or somethign simimlar, knowing you would fold to a turn blank?

Or, even simpler, you raise TAG, clear the field and are head's up. The turn blanks and the TAG donk bets again. What now brown cow?
