200NL KK 2xpaired board, rivered boat

-Comments on raise size on flop? I wanted to keep overpairs in, perhaps it gives a possible OESD too good a price?
-Turn check behind is a no-brainer, right? Planned to smooth call a blank river bet or value bet if checked to.
-How about bet size on the river when my boat comes?

I've been putting a lot of thought into these situations myself. Seems I get more calls from smaller bets or shoves then I do 2/3 pot value bets. Depending on how tight the opp is I'd be inclined to make it $40-45 or a shove.

1/5th of the pot might induce a bluff at the pot?

i raise on the flop, becuase i raise here with missed overs.
Id check the turn and bet 3/4 pot on the river hoping ive either got a station or im facing a monster.
Id bluff 3/4 pot here with AQ or 67s for that matter too making calling with a pp look like a possibly good call.
