and continued
By way of comment:
- W's 2♣ was Benji - 8+ playing tricks in some suit or 23+ balanced
- E's 4♠ and first XX were expressions of confidence in partner
- after N's insufficient 4♥ E seemed to think it might be worth offering W an extra option
- S's second X was presumably based on a conviction that her first X couldn't have been a misjudgment
- E's final XX seems to have been based on the view that when partner bid 4♠ she knew what she was doing and was more likely to have been right than S
The hands were as follows: N led away from the ♥K; W won perforce, crossed to dummy's ♦Q, and played ♠10; when S didn't cover and W ran it that was 12 tricks for a rather improbable +1880.
Has anyone else had an auction where the same redoubled contract has been bid twice?
