heellooo fellaaas ,

I wonder about my betsizes in such spots. UTG-reg (1,2k hands on him) opens 12% from that position and cbets around 48% flop. So flop i bet for value and protection pretty standart i think. 12% open looks pretty tight to me so i doubt he can have J8hh in his opening range, 99 i expect majority of ppl to bet the flop pretty often, so basicly i consider myself always holding the best here. I put him on 88+ all pockets with alteast 1 hearth.  I really cant put him on other range than pockets with w 1 heart in them, so i chose to give him a bit better price - but i think my hand gets extremely face up that way, unless i balance it, but i dont think ppl pay much attention to this on 100nl zoom. On the river i'm really not sure .. Any thoughts guys ?
