My guess without stats is that he's not 4bing for value with 5%, it's either mad pair or a bluff raise cos he got 3b by a button (and you made it seem to me like you 3bet wide).
I think his 4b sizing means nothing unless you've seen him show down hands. Many players 4bet bigger for value, while others do it small to try keep in weak hands. Others 4b bigger when they're bluffing because they feel they'll be called less of the time, others again may 4b less when they're bluffing so they lose less when shoved on.
It's too small a sample to draw any conclusions, but 4bing 20% of the time you get 3b is pretty standard IMO.
Also, not sure if you included your 3b stat but I didn't see it, this is hugely relevant to how often he will 4b you.
A guy playing this tight probably isn't opening more than 20% from the co. 20% of 20 is still top 4%, which JJ is bottom end of so fold isn't bad...
Having said that, I'm not sure whether it's better or worse than a call. Considering his bitch 4b sizing, he's made it like what $2.75 more or something to win like $7.75?
Based on the fact that you just know he's betting the flop 100% of the time for vale or as a bluff, so I view this more as $2.75 to win at least $15 (that's if he half pots the flop, which is standard, wouldn't view this as weak if I was you). So that gives you like 5.5:1, and you hit your set ~7.5:1. Plus I think a lot of the time here he's 4b'ing air because he thinks you're FOS, so once you call him on the flop and he's OOP, he'll opt to check down.
I really hate the king because a huge chunk of his 4b range beats you now that AK combos are good. So im folding that old flop. As played call flop if board is Q high or JJ is an overpair and shut down OTT, because I don't think many vils are capable of bluff shoving in 3b+ pots, so until I see otherwise, they have cred in my eyes
Also, I don't know much about zoom but I'd assume raises and reraises are skewed more heavily to bluffs than in their ring game counterparts, having said that, I don't think I've ever seen a good player 4b TT at 25nl SIXMAX, everyone wants to setmine regardless of the price and associated odds
. I do see AQ very occasionally, so IMO you beat nothing, flip with most and get it in bad often if you shove pre so stay right away from that nonsense
