I don't like checking the turn. He could be on a FD, a wheel draw, or backdoored into a OESD, so that's 9 + 6 + 6 = 21 cards that tend to paralyze you on the river, 21/46 = 46% of the time your decisions become more difficult and only 2/46 = 4% will your decisions become easier.

If you bet and he c/r you after calling your raise on the flop, I think it's tough to make the call, and it will be just as tough a decision on a non-scare-card river, so checking is pure "Hey, here's a free card, let's postpone this until the river", where it's often tougher.
