I don't have a hand converter but I'll try and replicate it as closely as possible.
CO: 1510 chips
BU: 1690 chips
SB: 2680 chips
BB (Hero): 1620 chips
Blinds are 50/100
Hero is dealt: A♥ 7♥
CO folds, BU folds, SB raises to 300, Hero reraises to 1620
My reads are that the SB is using his stack to raise consistently, but is not going that crazy. I put him on a decent enough sized range though, including suited 1-2 gappers. Do you think that I can get the SB to fold a better ace here?
