This week we see the value of paying attention to the vulnerability and working together with your partner to obstruct the opponents. When people hear the word "preempt" they immediately think of 3-level opening bids. But there is another kind of preempt, called a "cooperative preempt": a partnership realizes that its combined assets include nine, ten or more of a suit and few enough high cards that the opponents almost surely have a game.
Here is a hand from the 02 January 2008 club game illustrating this idea:
Dealer South EW vul |
T 9 8 4 6 5 2 9 5 Q 8 7 5 | |
Q A 9 8 4 A K J 2 K J T 9 |
J 3 K J T 7 3 8 7 4 3 4 3 | |
A K 7 6 5 2 Q Q T 6 A 6 2 |
South opens a routine
Did you look at North's cards, count 2 HCP, and automatically pass? If you were vulnerable and your opponents were not, being cautious would be wise. But you know your side has at least 9 spades and is likely to have less than half the high cards. This is your one chance to tell your partner. North can jump to
If North had passed, East would bid
Now it is South's turn: South has a sixth spade and a singleton heart -- and is, therefore, the only person at the table who is sure that E-W can probably make
West, with a monster hand, can only double
