Preflop: On the Button Against A Raise (Pokerstars $11 Deep Stack)

[SunKidDance]

Hi,
I'm just curious what the "right" play is, given the following situation:

PokerStars $11 Deep Stack No-Limit Hold'em Tourney, Big Blind is t100 (9 handed, 30 min. blind levels) internettexasholdem.com

UTG+1 (t4418)
MP1 (t4820)
MP2 (t14695)
MP3 (t2315)
CO (t7125)
Hero (t3807)
SB (t4080)
BB (t7670)
UTG (t6350)

Preflop: Hero is Button with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">UTG+1 raises to t500</font>, 4 folds[/i]</font>, <font color="#CC3333">Hero to act</font>.

The player UTG+1 is a tricky/trappy player with a Limp rate of 40% and Preflop raise rate of 3%. He betted very aggressively in nearly every pot after the flop.

So, what is a "right" play in this situation?

Thanks for your help,
