i'll take the unpopular approach and say fold. if you 4 bet and fold to a shove, you're putting over 20% of your stack in and leaving it. if you call and UTG shoves or 4 bets, you can't really call. if you 4 bet and the CO flat calls and you totally miss the flop, what are you going to do? the only hand he'll really fold in that spot would be AK if you cbet, and you'd be cbetting over 50% of your remaining stack. it's just a poor spot, imo. if you really want to play it, i would open shove to save yourself the tough decision / change at being outplayed later and hope to just take it down, but that's a tourney style play. i'd drop it.
