re: Poker & Folding this in a long term is profitable?
As others have said, your 3-bet is to small. My standard size here would with 10BB, and frankly at 2NL most players are so bad, that you can also get away with making it even bigger, when you have a great hand like KK. By going so small you are giving them great implied odds, if they make a casual call with a small pair, a suited connector etc.
Postflop first of all, we should just ignore his silly little two cent bets, because they are mathematically meaningless, and pretend that he checked to us. So you are betting the flop for value, you are betting the turn for value, and then you fold to a mini-raise.
I dont like that at all. I will admit, that when bad players take a line like this, they often have a very strong hand. At least something, that beat an overpair. But at the same time, when you bet the turn, you have already put half your stack in the middle, and you should really not do that, unless you intend to stack off and think, that this is profitable.
So either check back the turn, which in this case mean calling his silly little 2c bet. Or get it in, when he raise you, and hope you are somehow good. This also boil back to preflop, because if you go bigger, he might not casually cold call your 3-bet out of the blinds. And if he does, the pot is so large, that KK is just an automatic stack-off postflop, when there is no A on the board.
