non nut flush heads up vs aggro opponent

[donkeykong2]

villain is very aggressive and pots 90% of the flops if checked to, he also calls a lot and tries to take the pot away from you later. I bet/called him down pretty lightly and won 2 50$ pots with just top pair and weak two pair calling his float/bluffs on the river but recently lost a lot of smaller pots folding to his aggression on the flop not getting any hands.

Seat 1: Vollhorst ($71,60 in chips)
Seat 5: Lerppa81 ($273,15 in chips) (on the button)

Bet flop?

Dont start checking just because your opponent is aggressive. You need to be aggressive back. He probably isnt an idiot who will stack off light so nutpeddling is not a good option, especially hu.

yeah, i did value bet top pair over two streets before, but in this case i thought it was good to check to let him make his usual bet because i sometimes want to have a hand if i check it to him. i eventually stacked off in this hand to his better flush and i was wondering if i had to stack off here or if there was any way to get away from this.

Second nuts HU vs. LAGgy foe in re-raised pot? BBV. Fold pre-HU.

you are probably right, just the way i played the later streets of this hand was pretty embarrassing. i made a tiny turn lead, got raised, called and check called all in on the river, somehow hated it.
how good of a flush would you need here to make stacking off marginal?
