99 with a couple decisions

[Garland]

If button is aggressive like you say, he's guaranteed to bet. Check to him, and then check-raise. This should better define his hand as he’s likely to 3-bet only with a better pair since SB is also in the hand.

Leading the turn is great.

River. Eeks. Not much you can beat but a bluff and therefore, you should try to induce one. The SB was likely on a spade draw and missed. I’d check to the button and see if he bets. If SB calls (raises), you can safely release your hand. If SB folds, you should call and hope his overcards don’t include an A.
