Bet/folding when he raises his draw again on the turn is a disaster.

Bet/calling a two outer is bigger mistake than offering a free card to a hand that has a lot of outs and will call a bet but will likely bet if checked to.

Check/calling when your opponent will bet most of the time anyway is not a disaster. It's perfectly fine when your hand is ahead enough to see a showdown but less than the majority of the time. Besides that, the opponenet will bet this turn most of the time with whatever he/she raised the flop with...including worse hands, draws, or better hands. People get stupidly aggressive in these situations and I'd much much rather take a line that gets me to showdown with JJ than a line that includes a fold.
