Hero has black aces and wins pot.

OK, I'm not sure I like my line here, but when I get 3 callers to my $20 raise I go into caution mode.

My reasoning:

Villain could have any hand here, so I can't rule out 9s, 7s or even 97s. QQ is unlikely, but you never know with a donk like this.

I thought if he had a weak holding then he would fold to a big raise (I actually think a minraise might be in line here, even though I never do it). If he has me beat, then I'm building a big pot that I'm going to lose. So I decide to call.

How do you play this to extract maximum value?

What is your play on the river?

I think I played this was to weak, but when I get 3 callers I usually shut down.

All thoughts appreciated.
