SB is good and aggressive. He will fold most hands if we isolate but will shove a lot if we call.
BB is a total nit, and will play top 4-5% of his hands regardless of our action for all his chips

UTG is an aggro donkey and his range is ATC here LDO

I think calling is inviting SB to raise us out of the pot, should I fold or raise, and if raise, to what?
