The video, starting around minute 17, only discusses what to do to the jam. UTG raise to 8K, hero 3!s to 18K in MP1 with 120K effective to start hand. Hero thinks villain only has QQ+/AK and folds partly as sort of near bubble.
It used to be they would say here not to 3! if you have a close decision to a push. I would prefer to flat call initially, but would call the jam as played. Is the 3! OK? Hero is mainly a cash game player.
