To everyone that is saying check through this river, I'm assuming you're saying this because we think our KQ is only getting called by better hands on a third barrel.. ie: QQ,66,A6 or maybe AQ. So does this mean you are all also checking through KK and AA on this river?

The only difference I see between the KQ hand and KK/AA (based on villains PF play) is that we are now ahead of AQ. I can't imagine not firing KK/AA again on this river. Are ppl checking through with those over pairs as well?
