It seems like when I have position in heads-up pots, I enjoy a lot of fold equity. But when I raise or re-raise to isolate and someone comes in behind me, a large pot is created. The large pot makes it much less likely that I'll win the hand before the river card is dealt. And if the pot is large enough and my hand is vulnerable enough, I would prefer to win before the river card is dealt even if I have the best hand on the turn.
