U almost never have to com a 7 winner or a 7 loser. I see people all the way up to masters do this too often so I will post my thoughts on it.
7 as a winner - Just think about it. Single 8 or single 9 should com so why do u have to com that u are winning with a 7. Be confident in your 7s. If u didn't win with your 7 i feels as if it wasn't your fault. Save your com.
7 as a loser - I think that if u are needing to win with a 6 or lower it should to be commed. Therefore comming a 7 loser is almost never needed. The 6 winner should com. Also 78 or 79 gets commed way too often. It's the same as a 7 com. Now if u hold 789 then u should com the 7 but the other 2 combos are not needed as a com because it's a losing 7 com.
This is why 7 is the SWEET SPOT OF THE GAME!
