Gonna agree with bazzaboy on this one the raise to 3400 would be my standard play here too. You are one off the button with a good hand in position. Remember everyone will be playing very tight and playing quite obvious so my plan would be to fold to any aggression from my opponents after they called my preflop raise. 3 of your 5 opponents have roughly the same amount of chips as you so be the aggressor and take chances with these hands, those chances more than likely got you there in the first place don't spoil it now by playing like a pussy (sorry for the use of this term just fell that it's appropriate here)

playing too tight in these scenerios is the single biggest mistake for a poker player IMO don't let that player be you.
