There is no way Justin would ever bid 3C, it's non forcing! After 2C the power of our aces has gone up a lot...if partner has a hand with 6 clubs that's pretty weak like Jx Kx xxx KQxxxx or Ax xxx xx KQxxxx game is cold. If partner has a random 10-11 with 5 clubs, I definitely want to be in game with points, aces, 2 possible sources of tricks, etc just on power. So basically any time my partner passes 3C, I will feel terrible about it since I think we have probably missed a game.
