At IMPs, GIB miraculously comes up with the best lead of a club, ensuring 3NT is going to go down 5 tricks.
Sadly, once it gets in, it decides to try the only play guaranteed to let the contract make.
Blah blah, GIB can't simulate due to impossible bidding, I know. Regardless of the excuse, this is pretty rubbish
But this is how daylongs are designed to be won/lost. (This was only enough for 7th place sadly, due to one flat board I was dealt.)
