$11 PP overpair vs flop AI RR Lvl 1

This kind of thing happening enough I need to settle whether I should worry about it or not. When you have an overpair to a flop, and someone re-raises you....

Example:
No reads, we barely started.
NL Texas Hold'em $10 Buy-in + $1 Entry Fee
Level:1 Blinds(10/15)
Total number of players : 10
MP ( $800 )
Hero ( $800 )
Seat 3: ( $790 )
Seat 4: ( $725 )
Villian ( $1120 )
Button ( $890 )
SB ( $675 )
BB ( $660 )
UTG ( $800 )
UTG+1 ( $740 )
Level:1
Blinds(10/15)

I usually assume he has top pr and call. (I've seen call/pushes like this with A8, so maybe I'm getting sucked into bad play?) Is the threat of 2 pr or a set enough to drop a good hand? Under what conditions? For example, this is level 1, so foldable? if at level 5 no? Should I just realize 5x rr to me I better have a set, and fold KK AA AQ etc? What if it was just 2x rr for 400? Or am I worried over nothing cuz he's just got a flush draw with A/images/graemlins/spade.gif Q/images/graemlins/spade.gif ? even then, calling a rr.... lvl 1... fold a better idea?

Raise more than 45 preflop. And call that all in as fast as humanly possible.

Definitely, call with the quickness. You'll see QJ, KQ, AQ, two random spades, 97, T9, and a myriad of other utter crap here some huge (80%+ at least) of the time.

But yes, raise more preflop!

Thanks for the feedback.
Raise how much on level 1? Typically I've been opening with 45 (call + 2xBB, which I do at every level). I've heard add a BB for each limper. I've heard at level 1 you have to bet much more (60 + 1BB/limper?). Or does pot-betting take care of all that better (which would be 65 in the example).
Thanks!

I'd go with t75. Maybe t60 but at an $11 they'll call for t75 if they were going to call for t60, so you might as well get more chips in the pot.

I like t88 and t77 because they induce reraise all in or at least get em thinking about you more.
