Fold and forget it ever happened?

You're giving him 32 straights, so all offsuit hands, but nothing else?

If he has 32 straights (all 78 and KQ), then he has 9 J9's and 3 JT's. People do dumb things with seemingly good hands, so he could show up with QJ here (12), or KJ (12). Could be bluffing with 89 (12).

This is the absolute top of your range, other than raising KQ on flop sometimes. I'm not finding a fold here. The only question is call/call or jam to me.

Seriously - Focus on marginal hands in difficult spots. Worrying about whether your top set got turned by a straight on a coordinated board isn't worth it.
