Preflop: Fine WP

Flop: I guess even for that extremely sizing we can just flat given the SPR - raising small could be an option but I'm leaning towards just flatting.

Turn: Flatting or getting the rest 7.5$ in here will probably be the same. With such a nutted hand and not a single really annoying River I would just flat - for the off chance villain is going crazy with something.

FWIW: I think getting it in pre is a losing play here given the the positions and given my information on MDA about the population - so I def. think flatting the 4bet is the way to go here.
