Turn betting is probably ok but I don t think anyone is folding a pair so you can def lay a better price for yourself. Std sizing should likely get enough folds although I m sure its very close 3 ways in passive games where dudes will check more then they should.

Not bad but I would rather choose a smaller sizing.
You could use psb or over with your TxXx.
Most villains at these limits don't pay attention to your bet sizings anyway.

Bet turn and river but 50-70% pot. Versus four checks betting turn should be everyones standard move.

I prefeer bluff flop and turn clubs

OTT, I don't think you need to use this sizing as villains have a range that crush this board. you want to make a J fold, but will he even fold it? I don't think you should double barrel on the river.. I can count 61broadway combinations he won't fold vs a bet and got you crushed

I personally think turn could be fine as a check or a small bet to make him fold his Ax that beat you and 65s, .. type of hands. But none of these hands have much equity vs us and we need to get it through 2 people so I don't think we obtain enough FE and we don't have any good draws.. I think a hand like KQ would be better as we block KJ KT etc + have 2overs+a SD
