KK 3bet pot IP - CO vs. MP

I think it's well played.
You get a lot of players at NL 2 playing like this with small pocket pairs then trapping with them.
You have no draws to provide extra equity.

Nice try OTR by opponent though

Do you think you get any Overpair to fold with that sizing OTR? He might get AK, AQ, AJ to fold I think but JJ+ and AT will likely call with this bet size.
Why not bet large 2x+ to get more to fold and also to extract more value with Monsters against Overpairs?
What would you do vs. c/r flop? Call down? If you call a c/r flop, you must assume a 2nd barrel and 3rd barrel from aggressive opponents.

I would go most likely for betting the turn for value and protection against random villains on NL2.
I don't think you need to think to much about balance ranges on NL2 against villains that doesn't know much about ranges.

On NL2 players aren't thinking like pro's and against a over bet on river I would most likely fold any over pair. It's almost always value on NL2 I think.

If villain would check/raise flop it's really villain depended, but it smells like a set when it happens. 2 pair or straight are unlikely in a 3bet pot and than I would consider to fold. Not sure a random NL2 is capable to check/raise bluff on flop and bluffs on multiple streets.

Flop: First of all be aware that this flop can not be played as 1/3range cbet, because it hits well in villain range and not in yours. Its because you have plenty off combos like AJo-AKo, KQo and your opponent shouldnt called them preflop.
Optimal strategy would be to mix bigbet or X, however on nl2 I am always betting KK big,, same on the turn and shove river. So its Bet50-66->bet66-75->jam spot on this runnout.
