Folding KK Preflop

[CarmeloAnthony]

6 handed .25/.50 live game
My image: LAG
opponent: loose/Passive/preflop but tight/passive post flop play

hero - button - $55
villain - bb - $40
1st raise
I have KK and raise on the button to $2.75(my history i've been raising very often 75% of the time)

2nd raise
villain raises to 6 straight.

3rd raise
I hestitate and raise to $15

4th raise
villain doesn't think too long and pushes all in....

Conclusion
is this an obvious fold in these stakes?

thoughts are welcome

Welcome to the forums.

I don't fold KK preflop.

When your opponent goes allin, the pot is 55, and you have to call 25. You are getting better than 2-1 odds on your call. It seems that there might be a reasonable possibility that your opponent, especially at these low stakes, could have QQ, JJ, or AK, and with any possibility that he has one of those hands, your call is probably right.

You might also get better advice if you posted this in the NL forums. This is the limit holdem forum.

Post elsewhere, but they'll just tell you to call.

You need 30% equity to call. You'll have 18% equity if villian has AA. You'll have 82% equity if villian has another pair, so villain would have to have AA 80% of the time for your call to have a negative expectation. You're not facing AA 80% of the time in a .25/.50 against a LAG in a SH game, even live.

Thanks, yeah im new to this forum

i'll post elsewhere

SeaEagle, how do you calculate equity where do you get these numbers 30%, 80% and etc..

Actually, I didn't need poker stove for these, since they're quite trivial. But PS is awesome for figuring out showdown equity - every poker player, limit or NL, should have it.

In your hand, you are putting in $25 to win $55. You need to win 31.25% of the time to break even. I rounded that to 30% equity.

Based on the fact that you'll win 82% of the time if your opponent has QQ- and 18% of the time if he has AA, you can calculate how often he has to have AA for you to win 30% of the time. [I disregarded the chances that he'll have another hand, most notably KK and AK, for simplicity's sake].

As it turns out, if he has AA 80% of the time and some other hand 20% of the time, then (.80 * .18) + (.20 * .82) = .308, or you'll win about 31%. So if he has AA 80% of the time, your call is roughly break even. If he has it less than that, your call has a positive expection.

so your saying anytime you have a pair and someone else have a over or under pair you need to win 30% of the time to break even? Or is it when your getting layed $25 to win $55?
I'm Confused

Sorry i'm not good with this whole math aspect so please be patient with me.

Hopefully you've posted this in a NL forum as you're asking some pretty basic questions.

I would suggest you read at least a couple of books on poker theory. Sklansky's Theory of Poker, Harrington's NL books, the NL book by Miller & Sklansky.

You'll have to understand basic pot odds and equity in order to expect to win at any kind of holdem, even at very small stakes.
