KJo BU

Don't know what the experts do, but I'd consider folding KJo preflop versus tight players. It's not a powerhouse, and comes with the danger of domination if you hit and get action. After his turn cap, I'd put him on A♣ 90% of the time. This is a mathematical fold right there. Seeing river costs 2BB. I'd never really fold of course Raising on the river is burning money.

KJo is a fold against UTG OPenraise. It's ok to 3bet against a Mp3 Openraise but against UTG it's a fold! This hand is massively overplayed again. Bet Turn is fine of course but think about what his range is probably gonna be if he's checkraising this turn. You have the second nuts so what hands he can reasonably checkraise the Turn with? Q♣ and A♣ and not only that he's got more A♣ than Q♣ in his range but additionally he'll be obviously more likely to checkraise the nuts than he's likely to checkraise with the third Nuts. Q♣ is actually not a checkraise but just a check/calldown as you're facing the second or the nuts too often. After he did checkraise the Turn, you should be just calling down. 3bet is spew. Is there any specific read that justifies giving so much action?
