Donk bet 3 barrel into my two pair? NL400

[Eternal]

Villain is 16/8 with 34% steal attempt
He's a regular at this level. I haven't seen him do anything too stupid in the past. Villain should know I'm a regular and that I'm pretty aggressive at times, especially in position.

This is an interesting donk bet. I usually raise these on the flop even when I have air, but I was just sooo suspicious. I decided to call for pot control and evaluate later streets. Thoughts on every street? THank you.

arrrr in!!!

i am willing to call here. i think you have the best hand most of the time, but he has a 6 sometimes.

[chicken10der]

this is one of the strangest hands i've ever seen. i cannot put him on a hand that limp/calls then goes nuts on that board. i don't see a 16/8 doing that with like a 67s or something. 66 would likely check flop, as would a slowplayed AA. KK and QQ are pretty definite pf raises utg. i have to call here, and expect to see either another AK or maybe AQ?

[MINETZ]

im scarred, most people wont donk 3 barrel on an ace high board. I think u see 67s a lot, the bad tags like to open limp that utg and try to play it oop.

[Jurrr]

67s,65s = 4 hands, quite possible
AQ = 6 hands, but unlikely as limping them is dumb
66 = 1 hand, matches well though many will slowplay
AK = 4 hands, even more unlikely than AQ
AA/KK/QQ = 13 hands, unlikely
air = possible, but unlikely as it would take total abandon to fire 3 bullets here

I think you are beat often enough and can fold, but I usually cannot find the button.

[Eternal]

Yeah, I honestly don't know what to do here. Especially his overbet on the river. Can I get other thoughts please?

[Kos13]

Weird hand. Against a regular, am I the only one that raises the flop and pretty much shuts down if called?

I think you're beat, but a call isn't terrible. The only hand that really makes sense is 66, but I can't just give someone credit for quads. Do 18/6's limp/call with 87s, 76s, or AQ?

I'm guessing you folded...? If not, please eventually post the results.
