I fold to the turn bet... I'm pretty sure he liked the flop.. and at best I'm guessing ouor A's and Kings are only goign to be good 1/3 of the time, He's probably got a five IMHO, or at least we gotta give him credit for it. So with only two outs (adjusted for the odds), we need 22-1 to call this and it just aint there, especially with the SB calling, he may have something to... We can't call on the strength of AK alone....

I agree with marm on the turn, however if I called the turn, I would have called the river also. It's only one more BB and you're getting better then 10:1 odds. I will almost always call the river with better then 10:1 if it's HU just to make sure he isn't bluffing.

You didn't say what type of image you have at the table or give any idea of how these guys were playing. If you had been folding a lot of bets on the turn and river because your hand hasn't hit then there's a better then 10:1 that he's a decent player and figured he could bully you out of the pot.

With SB in the hand also, this chance is smaller, but if he's put SB on the FD and he knew it didn't hit, then he may have thought he could bully you both, especially if he's been that type of player...

I have difficulty putting him on a hand because he cold called MP1s first raise and did the same with the cap (he couldn't raise at that point, but he knows hes up against some hands.

I don't like the check/raise on the flop. That's usually when you've hit a marginal hand and you want to take odds away from somebody, it's also for when you know somebody is going to be behind you (which I guess since MP1 capped, it's a reasonable assumption)...when MP1 checked, CO probably smelled the fear. When you check/raised, he probably looks at it like I would and figured you hadn't hit your hand and were trying to bluff also...he may have just out played you.

There is a better then good chance you were beaten by something like JT or QT, but with the way the hand went down if CO is a decent player and has been playing with you for any length of time, he may have just got a good read on you and decided this was the time to push you off your hand...
