Here is a hand we played at the club today - our opps sitting N/S bid and made 6♠
During the auction North paused for a very long time (North acknowledged the pause) before bidding 4♦.
I considered calling the TD - but didn't.
South then bid 4♠ so I thought all was ok, then North carries on with 5♠ and the auction ends in 6♠.
By this time I feel too silly to call the td
Anyway, if you were TD and had been called how would you have responded?
