Suppose you are in the main event at the WSOP. You have 12K in front of you and blinds are 100/200.

You have the button and it folds around to you. You wake up with QQ and raise it up 3X making it 600 to go. Little mucks and BB who is Barry Greenstein re raises 900 more.

Barry as usual has been playing fairly tight, you immediately put him on AA,KK or AK..Flop comes A Q Q.

He checks to you and you decide to play fast and put a feeler bet out of 1200. He smooth calls. Okay you now figure kings are out and he has AA or AK.

Turn is a blank. You feel if he checks again and you check you can at provoke a bet from AK on river. If he has AA well you are getting excited for the double up.

You both check turn. Now another Ace hits the river. He comes out swinging for 3500. Okay now if he has AK of course you double as he cannot fold an Ace here but if what if he just made quads too...

Would you just smooth call river just in case or come over the top all in?

In a case such as the one you've described I'd probably go all in... I'm a bit more of a risk taker though. Others who are more conservative may choose to just call on the river. I suppose it's also a gut thing though and reading Barry.

My strategy for this play would be the same as the Wiz's I'd go all in...
