Matchpoints; lead ♠3; table result 3NT=
I was directing on this hand, a few months ago at a North London Club, and was surprised that my ruling was severely questioned by E-W, who were experienced players. North's pass over 2S was slow, and he selected 3NT on the second round, which made in some comfort. The BIT was agreed. I consulted three "kings", of a similar standard to the Souths in question, and all would have bid, two doubling and one bidding three hearts. They did not seriously consider pass. When I then told them of the BIT and asked them what they thought partner's hesitation suggested, two of them said, "Well you can't bid now, can you?", or words to that effect, not really understanding Law 16B.
My partner opened the South hand, as would I have done. If I had passed I would not have dreamt of passing it out in 2S and I ruled no adjustment. What do readers think? The field were generally in 4H, all going off, as my partner did, although it should be made with correct play. 3NT= was therefore a top, no doubt a contributory factor to the TD call.
