[AE6]

I'm confused about the preflop raise. Did SB raise to $8.50, or did he raise $8.50 on top, aka to $12.50?

If it's the second one, you should probably fold PF.

As played, I think you should just call. I think TT+ is not folding to a raise, meaning all you really fold out is AK, AQ, and AJ (if that's in his reraising range). If he does have one of those hands, it should become apparent by his play on the turn + riv, in which case you shouldn't have a hard time taking the pot away from him.
