Any stats/reads on villain?
He played it like he had a combo draw, 2 pair+ or, at least, something he thought was good.
Like AT, KT, QT?, maybe JhT -- or a flopped flush? I definitely wouldn't include T5s in his range.
I don't really like the flop CR but I guess it's a line you can mix in occasionally. You have to be certain the villain will bet as a free card can kill any possible aggression. Also, I'd CR more than 4X. After he calls your CR? he definitely has something.
The turn is your big decision. I'm not sure what the correct play is, but I'd start with a check. Based on his turn bet sizing -- call another small bet and fold to a PSB or shove.
If you do decide to bet the turn, check call the river to catch a missed draw.
I've never played NL10, but if you see players calling this light to your 3.5X opens, you should start opening to 4X/5X.
