Just some general principles at the micros:
- don't bluff stations, value bet them.
- if you bluff, bluff with equity

This range doesn't hit the board texture as hard as you think, and it's a pretty small % of this range that'll call down and get to the river.
Not so sure his range getting to the flop is as wide as you seem to think. Remember that he flatted your 3b pre, which you made against an EP raiser and a caller, repping a lot of strength. It's not like he just flatted an open. I wouldn't give him unsuited connectors or gappers for example. I'd surely give him all PP and broadways and Axs and a bunch of suited connectors.

What do you think his river calling range is?
