It was a 32 boards KO quater-final. It happened on my teammates table in the open room. It was their first board.
East opened a precision 1NT (13-15), pass pass until north balanced 2♣(!). It was alerted as both major to east, who was on the same side of the screen as north. Pass by east. South bid 3♣, but neither 2♣ or 3♣ was alerted to west, who assumed the bidding was natural. Followed by 3♥ by north then 4♥ by south. My teammate in west liked his club points and heart void (which implied bad trump break) so he pulled out the double. The play was straight forward, 4♥X+1, 990. Director was called of course at the end of the board. But to their surprise the director asked them to play on without giving any ruling!
Firstly I want to know what should be the proper ruling of such a situation. Secondly, there are a few pieces of background information that need to be taken note of: The player in south has a reputation for playing "immorally", if that is the word. He frequently takes advantage of players who are not familiar with conventions by not properly disclosing full meaning of his bidding (I know this from my own experience). Therefore, I suspect the 3♣ bid together with his failure to alert was intentional. Clearly he knew what 2♣ meant and he knew he would bid 4♥ anyway, but he wanted to shut out the 5♣ save by making the club bids looking "natural". At the same time he knew 3♣ cannot be passed. Everything was under his control. Now I want to know what you think the ruling should be.
Another ruling was on board 3. Over east's precision 1♣ opening, south overcalled 1NT (!), explained to west as different level different colour two-suiter. West passed with a 7 count because any other bid shows 8+. Then followed by 3♣ by north, who explained 1NT to east as SAME level two suiter. With long clubs east doubled. When south saw the bidding he interpreted 3♣ as "a strong hand, looking for suit" so he bid 3♦. So it appeared clear to west that south has ♦+♠. West liked his ♠KJX and 5 card heart so he bid 3♥ then 3NT by east. During the play, east who was convinced that south has the minors necessarily followed a wrong line and went -3 vul where 3NT is makable if proper information is given. Director was summoned again. This time the director blamed west for his 3♥ bid because a follow up double on 3♦ would result in 800. Again no immediate penalty.
My teammates were very unhappy about opponents' way of playing bridge and felt more upset at the lack of ruling. Their emotion got very badly affected (which i suspect is the opponents' purpose) and messed up the remaining boards. Remember this was only board 3 of a 16 board set. At the end we lost an unbelievable 66imp in 16 boards whereas my team is a very stable team and deemed slightly stronger than our opponents.
The most rediculous knowledge comes to me the second day when I got to know that the director was from exactly the same organization that the opposing team was representing. I wish to know your opinion on this too.
