KK 183bb deep

If you were only 100bb deep I think it's pretty easy to stack off but this deep I'd try to fold to the 5-bet shove and save a buy in. A lot of aggression at NL5 is almost always nutted hands.
As played I would bet larger on the flop around 17BB and decide from there.

Should've bet bigger otf, then reevaluate if raised. Those weak sizings are very vulnerable at micros, usually induce raises.

We are very deep, so I do not like to play for stacks.

It's NL4 versus a fish. He won't care how deep we are, nor will he recognise the fact that just because a hand like TT is an overpair he shouldn't stack off with it. I'm totally happy to get it in with KK here and if he's flopped a set then good for him.

I don't like the flop re-raise. Versus a normal opponent it is reraising with a bluff catcher. Versus a fish, well, while fish are fish, they usually don't hate money and try to win rather than lose big. Trying to exploit hands like QQ/JJ/TT/99 for 190 bb is so greedy that it clouds judgment and deserves punishment. Small hand - small pot. Getting it in here relies on the read that, in addition to being suboptimal poker players, they are also - as a general rule - downright stupid. If you insist on getting it in, then let him do the betting keeping his trash safely in his range. Usually, even this will not succeed, but will result in a smaller win if you are ahead. Be content with that. You have a pair, not a set.

Thanks guys for opinions. I sometimes find myself doing something on automatic pace I snap called his 5bet shove if you are curious. I can easily count profit by winning smaller pots and exploiting opponents but from time to time comes the spot where I can't press fold button and this pretty ruins my whole profit. I need to seriously evaluate each action.

With 100bb stack this would be ok. When we are deep I think we should't play for stack with only a pair. But I agree that we are ahead of his range OTF. He just got lucky.
