I 1/2 pot bet the river and he insta min-raised me, I called he flipped over AKd.

I didnt bet the flop because I thought hardbrick was going to bet it, since he had been trying to take down every pot on the flop when checked to, and that flop was one he likely would bluff at.

How much should I have raised on the turn? There was only $2 in the pot after his .80 bet
