I posted the problems in 3 other posts
So if you like don't read on here, but look the problems separately:
1) Bidding after partner overcalled at the 2 level. Comedy of errors (1)
2) Bidding after partners cuebid. Comedy of errors (2)
3) What to lead, if partner bids 2 suits. Comedy of error (3)
This was what happened at our table:
I bid a straightforward 3NT counting for 1♠+2♦+6♣ tricks, hoping partner to have something like: xx, Kxx, xx, KQJ10xx and West cashed 5 tricks. We stated, that 5 clubs is the correct contract, but didn't know, if it is possible and realistic to find.
The other table bid:
WEST NORTH EAST SOUTH
1♠ 2♣ pass 2♠
3♥ 3NT pass pass
pass
Our teamate led a ♠ (partners first suit) and easy 10 tricks were made.
There was a long dispute, what to lead with or without a double of the final contract.

Help
