I've got a question about the way the author of FTR played his hand that's referenced in the subject. He hit trip Jacks on the flop and made a very callable bet. The board showed 2 clubs. Shouldn't he have been afraid that the guy was chasing a flush?

I know that with my luck, if I made a small bet like that, the guy will call and a third club will come down. Then when he goes all in, I'll have to think about folding. Would taking it down on the flop be a bad move?
