Fold to his all in that is I check and he bets. I might not even call depending.

No set and no bet. I lose with overcards all the time.

Think about it. There is a jack on the borad. I can only beat AK, AQ, AJ and TT and below.

I lose to AA, KK, JJ. Hands that he might have called with. He would smooth call with AA and re-raise with KK.

Thanks CJ - I figured a set would just call here. I guess he is a new player. Not much to do with that hand.

As CJ C. says you can't just fold every time somebody throws chips at you.

I folded the winner yesterday in a MTT (at least he said that he did not have an Ace). I was CO first in with A8o and had about 1400 (start with 1500) and tried to steal the blinds by raising 3xbb = 120.

I did not pay attention to the BTN's stack - he had 6,300 - he called. Now HU.

Flop A66 and I made a solid 80% pot bet and he called - I did not like that.
Turn 7 and it went check, check.
River 9 - I checked and he bet the pot about 1/2 my stack.

I could not call. If I call and lose I have only $450 left. Either fold or raise all-in. I came very close to pushing representing A9. Instead, I folded.

There was some chat and he said he had QJ clubs.

My mistake was tangling with a big stack OOP.
