Turn is close. A lot of people will peel there with an ISD or two clubs, or a pair and weaker kicker, of course, and given that the 9 probably did not help them, betting there to get them to go away (or get them to call with the wrong pot-odds) is probably best. But yeah, if you get checkraised it pretty much sucks.

The other nice thing about checking the turn is you get to see what they do on the river -- do they take a shot at you with a busted draw or no? In this case, no, which is potentially useful information in and of itself.

Obvious bet on the river. I lean towards a bet on the turn but that's probably just being results-oriented. At 20/40 I know I pussy out on the turn, at 10/20 I'd be more likely to make the bet as I think I'm less likely to be checkraised/more likely I can trust the checkraise.
