3C P 3NT P
4S P 5C P
1. 2NT was alerted and explained as any 4441 with 16+pts
2. 3C was alerted and explained as asking about the singleton
3. West enquired about 3NT. North bids 4S and says that it shows a singleton club
4. On hearing this, South makes a 'hoh' sound and moves (but then withdraws) the pen towards the bidding pad. North hears the sound but does not see the pen movement.
5. After East's pass, South bids 5C which is passed out.
6. East places the lead card face down and West, after a brief discussion with north about his unhappiness with the bidding, calls the director.
'If you think you have been disadvantaged, call me back at the end of the play'.
There seemed no necessity to call the director back, however, I am curious about the rights and wrongs of the bidding sequence.
1. Should North rebid 5S and ignore the possibility that South forgot the system and misbid the hand?
2. Should North interpret the 5C as showing first round control and therefore bid 5H? If so, could South pass instead of bidding 5S or something else?
3. Is it right for West to call the director at the lead stage, or should the director be called at the end of the play?
