- I think the hand always makes if West has 3 or more clubs:
-
- Discard 2 clubs from hand, a club from table. Win the switch, cash two
- diamonds and two clubs, finishing in hand to leave:
-
- 65 - Q5 9
-
- AKQ3 - T -
-
- If West has turned up with 4 diamonds, three rounds of spades will squeeze
- him in the minors. If East has turned up with four diamonds, a diamond to
- the queen will leave no-one able to retain 4 spades.

- Well, as it turned out, they shouldn't have rectified the count. I presume
- 'Flight B Swiss' is some sort of US teams event (?): at pairs, I reckon they
- did the right thing.
