Folding to a pf minraise

[Cornell Fiji]

$50 buy in. 690 runners. 50 remain. Avg stack is 44,000

Both villains have good stats and are fairly experienced. Both have been playing very tight for the past hour but the bubble has just popped so they could be loosening up.

Table has been fairly tight preflop and I have been raising ~18% of hands. The table has not seen a flop in ages.I probably have a slightly aggro image but I have been card dead so I don't have the crazy lagtard image that I normally have.

Table is 8 handed.

Hero - 60,000
Button - 56,000
BB - 15,000

Blinds 1,000/2,000/300

Hero has A[img]/images/graemlins/heart.gif[/img]T[img]/images/graemlins/heart.gif[/img] UTG+1

Preflop:
UTG folds, Hero raises to 6,600, Button calls, BB pushes for 7,400 more, Hero folds.

I just felt like I was way behind hands that were smooth calling me on the button and that my push to isolate would not work against AJ+/88+ in a huge pot. He might have raised big pairs or AK but he might be slowplaying too. I don't think that I am ahead of the BB's range either (obv I would call with the huge overlay if I closed the action.) I think that if I call I am going to get shoved on by the button almost always.

Is this fold horrible?
