Blind Defense J5s vs 50/30/3 player

[WotaWaster]

Alot of these hands were 4 handed but he seems pretty LAG.

Question 1. Is this a hand to defend with?
Question 2. Is my postflop play to this point good?

[Leader]

Calldown from the flop bet. Your line gets you bluffed off the best hand or owned when he has a better hand.

[jstill]

preflop is fine, i dont like postflop as leader said just ck call the flop when its HU when its to u. no reason to bloat the pot or raise ur oop and no better hand folds

esp given ur read just let him fire barrels at u with air ur line gets u in all sorts of trouble
