Wrong, this is not even close to being enough to protect your hand.

You give him 1:3 pot odds when you bet 1/2 the pot. An opponent is about 1:4.9 to hit a straight (8 outs) and 1:4.2 to hit a flush (9 outs) on the turn. You'll be keeping an eye on reads so you don't pay him off too much when he hits, so you keep his implied odds down.

That's my reasoning for it being enough to protect your hand. I'd be interested to hear why you think it is inadequate.
