AKs flop decision

[private joker]

I feel like there's one post per week that's just like this, but no matter what, I still get tripped up in these spots.

Loose, dumb, donkish, aggro, weird Commerce 20/40 game (I know, redundant, etc.).

A passive below-average-playing lady limps in EP. A TAG raises in the hijack. A loose, aggro dude who has been running mad hot all night and 3-betting a lot goes ahead and 3-bets in the CO. I'm on the button and I find A[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/spade.gif[/img]. I cap it. (Any arguments for a different play?)

EP lady calls 3 more, hijack and CO both call.

4 to the flop for 17SBs.

Flop is T[img]/images/graemlins/club.gif[/img] 6[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/diamond.gif[/img]. EP checks, hijack checks, CO donks.

And I... ?
