I folded vs his 1st 4bet. My steal % against him was prob around 50. My fold to 3bet was prob 60-70%, call 3b% was prob ~30% and I hadn't 4bet him yet.
Let's see.
If you jam, it's 48 to win 107 (or 106.50, if you count the rake.) That's 45%. That's the price of AQo vs 77 (88-JJ are up to 2% worse).
If he folds, you pick up $22. Now, he has to have a load of air in his range here IMO.
If he calls with 22+,AK+ (every hand that is ahead of you), that's 7.1%, and you still have 39% equity. In this situation, you need him to fold 23% of the hands that call to break even. AQo vs 22+,AJ+ gives you 44% equity before we consider any folds.
If his range is restricted to the hands that crush you (QQ+,AK), his jam-calling range is 2.6% of all hands, and only 1.9% of hands after you see your hand. In this case, you have equity of 24.4%, and need him to fold 23% of the time to break even.
For a wider range, 22+,AT+,KQs,KJs (11.3%), your equity is 47.9%, and you simply don't need any fold equity.
I think it's an easy shove. If he's shoving more than about 11%, you're making money, and the shove is worth somewhere between breakeven and $17 or so, if he's folding 90% and calling only monsters.
