1/2, I've been weak :(

So many questions, so please do not take anything below as criticism, just genuine curiosity on the hand. I am going to jump right into the river action because it has be very curious.

When the river peels, there is now $132 in the pot, and it sounds like you have roughly $100 back. When she bets $90, putting the pot at $222, you are getting just about 2.5 to 1 on your money. Meaning, in order for you to call, you need to be right 1 out of every 3.5 times to break even (roughly 29% of the time).

You mentioned multiple times that she could have Ax, A5, 56, and 77-99. You even say A2-A5 makes sense, but none of those beat you in this hand. Only 5-6 chops the pot, everything else you win. Only non full house hand you lose to would be specifically 6-7.

Yes, she could have a pocket pair for a full house or 4-5 for a full house, but you do have a blocker for pocket 3s, and two of the 5s are already on the board. It is still possible, for instance with 4-5.

It comes down to, do you think you would win this hand 1 out of every 3.5 times in this situation. If you think that is the case, the answer is a call. You even said yourself “you think you win a lot here”, so this is something to consider in the future.

There is nothing wrong with folding because you think you are beat, but folding because you don’t want to be involved in a big pot without the nuts is probably not the best mentality moving forward. If you are only playing the nuts, people will catch on to that and exploit it moving forward, even if this was a correct fold.

Hey Chuck… I think Herm covered most of the basics. The conclusion being that the only hands you are losing to… could she have – those small pairs or small suited connectors.
Granted she limped then fired… likely Ace rag or even Ace rag spades.
The one open question I have is what kind of player is she? Has she been known to bet aggressive… has she shown some capability understand the game?
I just don’t see a situation here where you could fold. I get being gun shy, but your hand is so strong. There’s just too many ways for you to win vs. lose.
The one thing I will disagree (sort of) with Herm is the pot odds. I think about this differently, because to me it doesn’t matter “would win this hand 1 out of every 3.5 times in this situation”, as it only matters if you win this one. What pot odds doesn’t consider is the analytics that you applied to this hand, either from instinct or read. If you truly had no solid information (like her playing style, table image, etc.) then all things remain the same and I think its an easy call. If she has a habit of only betting the nuts or when she does play a hand, she always bets aggressive… then this is helpful information to steer the pot odds more or less into your favor.
Let me say one more thing and please just take it constructive. Fear is a horrible emotion to base your decisions on. This is why professional players are so good… because they will consistently put you in uncomfortable situations. You have to look past that fear, and make the decision based on your capabilities. If you trust your instincts, and your instincts said fold… then so be it… move on. But just don’t fold out of fear of being wrong and having a bad night. It only takes one good hand to change that around.
Don’t beat yourself up too bad about it… the one tough thing about playing 1-2 is that players can be very difficult to read and understand.

the one thing I would add, and maybe you already thought of this, is that sometimes your read on a player is that they are super strong is correct, but they are over-valuing their hand. So their mannerism and even betting (size,line,physical,etc) is that of someone who is sure they have the best hand…but they aren’t necessarily the kind of player to have put a huge amount of thought on what YOU may have in that spot. that being said, I think it was a good fold. you only beat some of her 5x, chop 66, any pairs over 6’s all would have probably been afraid of the turn 5 and less likely to bet then shove. You win here occasionally, but I think way more you lose….although ppl do crazy shit at 1/2 so who knows! lol…good fold good fold.
