Thanks again for the input. For those interested here are the results of the hands. I obviously shoved the river. I was confident at that point that I had V2 beat and thought the only hand V1 could have that wins would be 77.

V1 turned over K7s and V2 says he folded AKo so we scooped a really nice pot. While the end result was great I wasn't totally confident that I played the hand optimally, hence this thread. Not sure if we ever get more out of V2 and if so where and how.
