At around 15:00 Peter goes through an example of holding J10s and check raising on a flop of AsKsQc. He states villain (HJ) is betting a polarized range here. I thought villain would be betting range here, and this seems to be backed up by solvers. Is villain betting polarized here because they are an "ABC" Reg, or do we know this is a range bet now while we didn't 5 years ago?
