I think your play is very +cEV here. IMO Sorel's UTG raising range is wider than the Grand Canyon, and he's willing to 4bet any hand that he opens with. Therefore, 88 has his range crushed. Jamming is always +cEV when there is a significant gap between Villain's raising and calling ranges, and here I think the gap is huge, since I have to believe his 5bet calling range is pretty tight here (he'd have to consider mucking 99-JJ here). Even if you get called, which I think is happening rarely, there's a good chance you're racing here, because the less pairs he's willing to call with here, the greater the % of his calling range AK becomes.
