check behind on turn to get paid off on river?

Any elaboration as to why checking the turn with a set in a HU pot is REALLY BAD?

In fact, it isn't REALLY BAD, and betting isn't REALLY BAD, and pushing isn't REALLY BAD, and an argument exists for each.


But I am curious why letting an opponent who is drawing dead much of the time catch a card on the river is a horrible play......?
