Even at 50nl it looks like some people are mini raising pps or very strong hands still.
Preflop is fine, not sure about the flop. I'd let him lead out the betting, if he checks i have a go at him on the turn but am very wary of a reraise (set/stonger ace) His turn push tells you that your beat here imo so i hope you put it down. Im not married to this but i'd try to push him off here unless he comes back strong, i dont want a showdown i dont think.
My only criticism is that i dont lead out here but i would reraise any flop bet he makes to see where i stand.
