folds to me in the small blind, bakes is bb
Kingdan:
Bakes is BB with 8500

Been thinking about this, should I just be jamming my range here? I have approx 18bb.

I figure open jamming is the best way to play A5s. Should I be playing push/fold here? Normally I think you can make a case for jamming except for very strong and very weak stuff but I figure with this kind of structure I'd want more fold equity so shoving my big stuff too makes sense.

edit: I figure open jamming a5s is there best play here... but are there hands I shouldn't jam?
