I folded AKo preflop

Am I crazy?

1/2 full ring.

UTG raises, UTG+1 3-bets.

Folds to me in MP. I fold.

We haven't seen many 3-bets preflop at this table, and especially from UTG+1...however, these two guys were chatting rather frequently and someone had suggested that they might be colluding.

I lectured them both before folding and said "Alright guys, we better see a showdown. I want to see your cards..." Then folded with like 2 seconds left.

I don't like playing AKo to three bets. Am I crazy? Do you guys cap this or what?
