I started playing 50NL ring games a few days ago. Something I've tried a few times is to check-raise on a paired flop in the blinds.

Typically it goes something like this: I'm in BB with random junk, a few people limp in, I check. Flop is some rags with a pair, say 553. I check, it's checked to someone in late position who takes a stab at the pot. I make raise of maybe 2/3 of the pot, the original bettor thinks for a while then folds.

So far it's worked every time for me. Is this play likely to be profitable on average (as long as you avoid trying it on brain-dead calling stations) or have I just been lucky?

Here are a few examples:
