@Vincent Perkins Good old cue for that "old school" rear hand position is thumb on a chin, so in reality it is in between glued to the cheek and completely frontal position. It's dynamic, fast to parry and fast to block hooks, also your cross is less telegraphed and easier to hide behind a jab and maybe even less taxing on one's shoulder (mine is looser in that kind of position). Guys from Kronk gym used it successfully.
