Thanks! I currently have a system where I quite simply stop myself auto-4betting with monsters if one of my hole-cards is red so I can think a bit more deeply about the spot. This is one where I think I can go either way, but since I like your answers so much, this leads me to another question:
I think that, at a certain point, if the BU (or SB actually) is a big enough fish who we want to come along for the ride, but is not guaranteed to be calling another re-raise especially, I believe 4betting can become a serious mistake. If you were to try and gauge a 'line in the sand' for a BU/SB opponent profile beyond which 4betting would be considered a mistake, which stats or reads would you be looking at and what might they be?
To try and put it a little more simply, I'm basically trying to ask at what point between our beloved 60/35 recreational player who spews postflop, and the ok 28/25 Reg would our decision become close between 4betting and calling.
