By the way, consider check/raise bluffing
the flop. Yeah, you're not going to get any better hands to fold, but you're at least going to take it down pretty often. It's a drawheavy board, which may make him suspicious that you're on a draw, but what can he do with 77 or KQ? If he thinks you have a flushdraw, re-raising will be your invitation to shove on him, so wet boards like these are - paradoxically, perhaps - kinda good spots to bluff naked, specifically because you can have so many draws looking to get it in. And if he DOES re-raise, you may somewhat safely assume that you're looking at a hand that either has you crushed, or he has a draw himself - which, frankly, is a favorite over your hand.
I like what Leatherass said about making small pairs your "bluff balancers" in these spots. There's a lot of ways for him to have hit this flop, which makes the re-raise perhaps not ideal from a bluff success point of view, but then again calling down is not exactly a cheap way of winning the pot either if it hit his range hard.
