tough preflop all-in call

Pot odds 45.7%
Your hand against KK+: 18.2% equity: fold
Your hand against AK,KK+: 39.9% equity: still a fold
Your hand against AK,JJ+: 47.4%: very close to break even. He has 6 combos of JJ and 1 of QQ, 16 combos of AK, 6 of AA and 6 of KK. Total 34 combos, 7 of which you are a big favorite against. That's 20% of his combos. So his hand has to be something other than KK+,AK only 20% of the time for your call to be profitable. This is not unlikely at 2NL.

So if you think he is capable of doing that with only one or two hands other than AK,KK+, it's a call. Not an easy question to answer, it depends a lot on your reads on your opponent. At 2NL some people do that (call/raising) with their small/medium pairs or very strong hands and even sometimes as a bluff with a mediocre hand or because they are tilting. Some do it only with AA. Some do it only with their weaker hands because they always raise or reraise their strong hands to start with.

Without more information, I don't think I let go of my QQ in this spot unless I have a strong read that he only does it with KK+,AK.

FWIW, against AK, your equity is 56%, which is more than the 45.7% pot odds. In other words, if you KNOW he has AK, you have to call.

There are two other factors to this hand also...
1.I was a little thrown off by him not re raising the co? Part of why I called
2.I have no other reads outside of PT stats on him cause I was looking at the Grinderschool website,thinking about joining.That site already has me for -EV lol.
