This is all good advice. My reason for cking behind on the turn is that you are either WA or WB. Your opponent is drawing to at most 9 outs with 1 card to come, and I dont really want to play a large pot with a single pair.

When you ck behind the turn, you also give the flush draw a chance to bluff the river. Your opponent would also call much lighter on the river since you showed weakness on the turn.
