Well, JohnD, that is a judgement that means that pass is not an LA [logical alternative]. Mind you, it has to be a general opinion, not just yours, but if you believe that at least 70% of similar players would bid 6C, then there is no reason to adjust.
It is very close, certainly, and a lot of people would agree with you.
However, Mathias, I do not agree with you.
When a person says "It is teams" he does not mean he was thinking of bidding slam: to most people it means he has either bid a doubtful game, or he has not bothered with 3NT. Those are the two things that people do when it is Teams.
