Broadway casino Friday night. Villian is a semi reg, a rich businessman esqe type fish who gambles a lot pre and tends to be aggressive post, though i do see him station off with a pair fairly often too. I've been noticeably aggressive so far and very recently bumped up a bunch of limpers with 87o which won at showdown, and everyone was like "ahhh this fucking kid raises with anything" lol so imagine i've got a wide percieved raising range.
Eff stacks ~£280
He puts the straddle on to £4. 3 limps to me on the btn and i make it £28 with

. Villian and all limpers call.
Flop

Villian leads for £75, everyone folds to me.
What are we doing?
If we call what is our plan for various turns? Is he ever not following through here?
