he is 80/10 so he plays 80% of all possible preflop combos.'

go play w/ pokerstove and you will see that any 8x,7x,6x,5x,4,3x which are all pair combos or straight draw combos, these all are 72% of all starting hands and he is calling all these, so even he is folding all of his air he is not folding enough so that youre 1/2 pot is +EV , not even 0EV. the hands he is folding are max 20% of his preflop range and that is if he is folding all Ax and broadways whic he isnt, but even if he does its not enough cause you need him to fold 33% of his range.

you're equity vs his calling range, if he is calling only pair combos and straight combos, to hit on turn is 18%, so FE+ hand equity dont justify a flop bet. but he will call Ax and broadways and your hand equity + FE will drop a lot.

even if you dont bet turn and he doesnt also, the equity you have up to river is not enough so that when you hit, this would be a profitable play.

i cant see how this is + EV play vs this kind of player.
