To me it seems like he has a hand thats good right now but kinda vulnerable, like 66-88 and tries to get his chips in while hes still ahead since he doesnt want a scare card to come on the river which gives him a hard descision since hes first to act.But he probably knows that its close to the money. And maybe he tries to force u out of the pot with a weak hand like A3- A6 or deuces.If we take into consideration that he called a 22BB shove with 77 earlier, we can be quite sure he is not afraid to gamble with a draw hand or even a low pair in this situation since he got u covered in chips and i
