fighting the TAGs

[Wynton]

I believe I have some major shortcomings playing the tighter players, probably because I'm too focused on exploiting the loose/passives. So I'm looking for some general feedback.

One problem I have is that I think give too much credit to a "tight" player (i.e., VP$P 22% and lower, 15% pfr range). For some reason, I assume a pf raise from these types means a high pair or AK or AQ, even though I have similar numbers and raise with a considerably larger range. Thus, if the TAG open-raises ahead of me, I'm probably folding some hands that I should 3-bet instead.

And I think I might be giving up on hands too soon postflop as well. If I raise with something like AQ or even AK pf, and the TAG reraises me, I often don't fight for the pot if the flop is trashy. But it occurs to me that perhaps this is precisely the situation when I should show aggression, since these types of opponents are probably capable of folding overcards.

And maybe I should be doing more turn c/r bluffing against the TAGS also.

Any opinions (aside from just trying to avoid TAGs in the first place)?
