Basically I’m wondering if I should be turning this into a bluff. The PFR is short which is unappealing because maybe he gets a bit more sticky, but after his flop check imagine his range is heavily under pairs. I suppose his call on river could be reason for concern.

The sb probably starts pre with a wide range considering the small Pfr(for live standards). I’m unsure if the 1/3 sizing means he never has the top of his range or not. We do block T9, but a fair share of live players can definitely flat offsuit combos pre as well... I also don’t think the SB has any bluffs in range, and mostly has top pair or better, but the top part of range is possibly discounted given his river sizing

My feel is we can probably use this combo as a bluff, but I’m not very confident in the effectiveness. If we do go for the raise, I’m looking to make it like $110 and trying to get top pot to fold fearing the 4 liner on river
