Not donking the flop is good. Yeah, bet the turn larger. There are many good rivers to continue betting... As played, bet river like 55% pot to fold out high cards and missed draws. I think you have slightly more fold equity vs high cards when betting 55% pot compared to 50%.
that sounds like a terrible advice. If you choose a hand like Q3o ok it isn't the best choice but wathever. Q3s is an extremely bad hands to pick to put into such a huge iso range.
