At a club game today:
East holds S 4
West holds S Q653
West opens 1 NT (15-17), East bids 4H, West bids 4S. No alert but for the sake of this discussion let us assume that 4H was alerted as a transfer to S (West is a bit of a dreamer, although a very good player).
East 'corrects the transfer' to 5H which is passed out. At the end of play East berates partner for forgetting that 4H and 4S are to play, and 4C and 4D are transfers to H and S.
No system cards because it was a club game.
5 H made 6 because of the lead.
I let it go, wanting to avoid an unpleasant controversy, but in a different setting I believe it would be appropriate to adjust the score to 5S by West, down whatever.
Would that be right?
