Does "no pause for thought" start when the player becomes AWARE of what he has bid, not when he does it? E.g. partner grabs where he thinks is the 2♦ card, not the 2♣ card, plops it down and proceeds to stare off into space. Now if when he hears "ALERT!" and looks down and see's what he's bid, if he immediatly says "oh, I meant to bid 2♦", wouldn't that be an allowed correction?
