Game is live five handed 5-10 25 straddle utg.  Cutoff 3.8k opens 100, hero 14k 3bets tc6c7h5h to 325, small blind 20k calls, bb 1.9k calls,  cutoff pots, hero and sb call, bb goes all in, 4 ways to the flop 1900.  The sb and bb are both really wide here, cutoff almost always aces.  Flop Ks7d6h,  sb checks, co shoves 1.9k, hero?  

If I just call the small blind will call any piece and shove all better made hands, if I shove he will call all better made hands but will fold a lot of hands with pretty good equity.  Also small blind leads hands he wants to go with like wraps and top pair with gutter in these spots a lot of the time which polarizes him in my eyes.   I want to just shove now but maybe I can flat fold to when shoved on and go with a lot of turns when checked to.  

Anyways new to the forums looking forward to becoming more active and thanks for all input and advice
