Middle pair

[shant]

I'm getting back into SH after a long break at the full games so I'm just trying to figure out how aggressive I should be. I think I was too aggressive in my experience from before at the Party 5/10. Should I be playing this hand? Is this the proper aggression?

These reads are mostly from 3-4 handed play. SB is 35/15/1.8. He gets a little passive postflop, but I think has good preflop play. Button is 50/2/.6 and likes to call.

Absolute 5/10 (4 handed)
