[toss]

KJo is best raised if UTG is the type you want to isolate. If UTG is tight and unimaginative you'd want to fold. Calling doesn't fit anywhere in your position.

Flop bet good. Checkraising mjust bloats the pot with what may not be the best hand. You risk the flop getting checked through. You encourage people to stay in with weak draws if you checkraise works. Flop bet is good.

I like check calling the turn if you intend to showdown no matter what. By betting the turn we only gain when villain folds KJ or KQ. Villain with either raise or call with a better hand in which case we lose. Or he'll get away from QQ and weaker hands in which case we also lose. Checking lets him make the mistake of betting weaker hands and it saves us a big bet when he has a better hand. We can't fold the turn with our second nut flush draw.

When we check the turn we also encourage villain to bluff with worse hands. For this reason I think we have to showdown and call a bet on the river.
