As a director I was called to a table and it transpired a player had drawn a card from the bidding box thought about it and then put it back and then passed. This is obviously unauthorised information to their partner. I asked them to continue to the end of that hand and asked the other pair had they been damaged. The answer was no. If they were I would have adjusted the score accordingly. My question is was this the correct procedure and would this have been the correct decision if all players had seen the bid before they put it back in the box? At no stage was the card anywhere near the table.
