call. Bet WAYYYYYYYYyYyYyY more on turn. Bet more on the flop too.

you bet sizing sucks
bet pot on the flop
bet more on the turn.

if you do this, your river decisions (and decisions in general) will be much eaiser.
as played, well i'm a calling station so i would probably just call it.

e z fold, imo.

bet more on the turn.
