No. This hand was not misplayed. Short answer is, you should never be folding KK preflop in micro stakes. In over a decade, I think I have folded KK preflop one time. It was 100NL and I knew my opponent inside and out. You should really be playing your KK the exact same way you would play AA preflop. Even against your very tight opponents you should still be happy to get it in preflop. If you assume that your tight opponent will only move all in with AKs, QQ, KK, AA.....you will win about 56% of the time. If you include AKo, AQs, and JJ in the villain's all in range, you will win about 63% of the time. Therefore, unless you are POSITIVE that you are up against AA, moving all in with KK preflop will always be profitable in the long run. Like you said, there are some VERY RARE spots where an argument could be made for folding KK, such as being super deep stacked, but these arguments can safely be ignored in micro stakes ring games lol.
