Ok I'm just a low level guy still but I like lurking in this particular forum. First I don't think he has 7's because you have to be a damn good player to lay down the best full house on this board. Who really fears quads in his spot? I think he just has a pocket over pair. Nothing too big, maybe 8's or 9's?

And if you want to get more money out of him why work so fast? You have the hand won with one card to go. Instead of inducing an all-in on the turn why not just call him? You have position anyway. So if he doesn't make a move on the river you can at least value bet him to get a little more cash from him.

There is no way he has 77 here, you would have stacked him with that. He is worried about you having a 4 for trips. I am guessing he has an overpair or A7. A spade may kill any action on the river, but I doubt it. I believe he has $233 of his stack in a pot of $490 and about $160 left....call his raise on the turn and hopefully he bets into you on the river....if not push.

double check raise is weird by opp. I like to just call in this spot cause that will usually induce a bet on the river, thus making a huge pot. I go allin and they usually have priced themselves in for a call. you don't need to worry about getting 77's money here, so you just gotta figure out how to get other hands to pay off.

Posts about quads are pretty pointless. This situation happens so infrequently that youre better off making threads about other situations.

You're lucky you got any action at all.

if he loves the check/raise so much, i say flat call the turn and pop him on the river, you're at worst 96% to win the hand (vs Open ended straight flush draw). You have position, let him check/raise the river again.

so just call the turn check raise because you'll get it in vs other fulls by river no matter what and let him keep bluffing otherwise
