Table 1 has played 7 out of 8 boards and has just started the auction on the final board. At table 4 (from another match, playing the same boards), the set has been completed and the team is scoring up. "I'm glad I bid on over 4♠", says one of the players, with sufficient volume that it is heard by players at table 1.
Table 1 calls the TD and explains the overheard comment. The TD advises them to continue to play the final board for the time being.
The auction on this final board was:
It was the winning action to bid on over 4♠ on this final board as both 5♥ and 4♠ are likely to make 10 tricks.
Should the TD be inclined to adjust the score? If so, to what? Does it depend on how obvious the 5♥ bid was?
Now for the twist in the tale. When the TD talks to the players at table 4, they claim to have been discussing a different board in the same set, i.e. a board which had already been played at table 1. Should the TD be inclined to adjust the score now?
