Personally, I think I would want to raise stronger preflop (12-14) to make sure we isolate with just HJ (since UTG had limped). If SB cold calls a stronger raise PF and calls the flop, I think we should maybe be worried.

I would also probably bet the flop stronger to show we aren't leaving this hand. As played, SB, HJ may put you on AK/AQ overs.

Raise PF stronger, bet flop stronger. If SB sticks around in both of these cases, then he either has midpair 8's, 9's and doesn't believe you (in which case he has 2 outs) or has an overpair, set and we're WB. In this case, I say check behind the turn... I'm not too worried about HJ.
