Club Night Pairs.
Contract: 3NT.
Declarer (South) has been running the club suit and has now reached this position. On his last club, he now has to make a discard from dummy. He calls "any". Dummy plays the queen of diamonds and I (East) discard the ♠4. As I am playing this card, declarer suddenly wakes up and says "No, I mean a low spade - obviously". It might be obvious that he should play a low spade, but I was far from convinced that it was obvious to him when he called for "any" and suspect that he had forgotten that the ♠A had not been played. Dummy didn't seem to be following play either.
I called the director but, when they started arguing, I told the director that I didn't want to pursue the point (feeling a bit embarrassed).
How do you feel about this incident?
