AKo UTG, LEVEL 2 5.50 Rebuy 'Stars

[jaydoggie]

I have 1750 in chips. Dealt AKo UTG. Game is extremely looese. I think I made a huge mistake by only calling utg. what is an appropriate raise here? its really tough decision for me in the first hour of these rebuys, which i dont play too often. heres how the hand played out.

i call 30 hoping someone will move allin like they usually do and isolate me with a coinflip or better situation. EVERYONE ELSE CALLS. well not the end of the world im only in for 30. BB nowraises to 150. instead of instantly pushing, i now raise to 670. (bad again or still ok?)
next 3 players call. next guy moves in! FINALLY! no wait.. 2 people call before it gets to me, i call. next 2 call.

everyone had a variety of high cards, no pairs, no one else had AK. i win a huge pot unimproved, but i cant help but question the right way to play this hand?
