UTG is 20/17 with a 3-bet of 6.0%, F3B 75%
CO is 17/12 with a 3-bet of 5.2%, F3B 54%
BTN is 32/2 with a 3-bet of 2.4%, small sample
SB is 19/16 with a 3-bet of 7.5%, F3B 75%, squeeze of 7%

When SB checks I think he is giving up a lot with AK. I probably should have led out for $19 to see where I stand, as I think when SB checks then I have the best hand a majority of the time.

As played I checked and now CO who is the tightest player at the table bets. He has a WWSF of 38% which is very low, and a donk bet of 3%. Overall AFq by street of 37/25/13. I don't think he is the type of player to bluff in this situation or to bet with 88/99. But he could easily have JJ and betting for protection.

Thoughts?
