Bet turn TJ against unknown?

[Barrin6]

preflop raiser likes to minraise instead of limping so it was a standard reraise for me. I should have reraised more pf. The other dude I have no reads on as I just sat down. But anyways, turn, bet or check behind?

My thoughts on the hand :<font color="white">
I like checking here since QT and any other J/x is calling the turn bet. And any other J/x is ahead of my TJ ie. JQ,JK,AJ,J9 which made me want to check turn. </font>

i would check. The board is quite dry. A draw like QT might bet out the river if missed. If the T falls you bet get value out of it. Obviously for pot control vs possibbigger hands as well

Ok now lets say turn comes King of diamonds. And villian leads for full pot on the river? Easy fold?
