[AtlUmpSteve]

I will give you a positive "it depends". If it is a discussion, I want to give the coach every benefit of attempting to get the right call; depending on the level of play, my level of confidence in my call, and the congeniality of the conversation, I will willingly steer the coach to that conclusion (me: "Would you like me to check what my partner saw from his/her position?").

If the coach is showing off, yelling, waving arms, being boisterous, s/he will need to do everything right to get that consideration from me. And, if I am positive about my call, I will not hang my partner by pretending to ask.
