Final Pot: 19 BB

Ugh... this has happened the last three times with my big pairs, AA, KK, KK.

BB is a fish. He's not passive, or aggressive, but he tends to bet weak pairs and autobet overcards simply because he has the opportunity. This is different though, a true LAG has to make this play with a losing hand.

I'm not sure I would fold here. There are 18 BB in the pot and its only 1 to you.

BB's top tendencies:
Call or check/call
Autobet
Bet unraised pot

A check raise or reraise indicates powerful hands and a stop'n'go is pretty much the same thing in this situation due to the obvious board.

I also folded due to the players ahead of me.

Here's the problem with posting this hand:

Under normal circumstances it's absolutely silly to fold AA for one bet in this large pot on the river. (Even if BB has a 9, trips would only improve him to a 2nd-best against a king) But if you're going to defend your read, which may or may not be justified, what can anyone possibly say to help you?

[Yobz]

I would call and fold if raised behind me. I want to call because its 19:1 and if its raised then there is not even a 5% chance (unless you have some damn good reads) that you are ahead...

[DontRaisePlz]

Good point.

[bottomset]

very few reads are 95% accurate, unless you have a large hand base w/ the BB ~500 or so, you shouldn't fold here
