Cappelletti over 1NT — part 1
In first seat you hold
♠Q 8 ♥A J 8 ♦A K 10 5 ♣K 9 8 6.
You open 1NT and your left-hand opponent intervenes with 2♦ showing the majors. Don’t you just hate that?
Bridge players have learned that it pays to compete over opening strong 1NT bids when they hold shapely hands. Generally, it’s best to compete with hands containing a long suit or with two-suited hands — usually with 5–5 or even 5–4 distribution — and appropriate values.
The object of the interference is not to get to game, but rather trying to obstruct the opponents and to do so safely. You hate it when they bid over your 1NT — turn the tables and do it to them!
For this to be
effective, however, you need a system to define your bids. One of the most
popular of these methods is called Cappelletti, a
treatment that is also commonly known as
How it works
Double shows a good hand, either a very strong balanced hand or (better) a hand with a running suit that can be used to defeat 1NT.
2♣ shows any one suit.
2♦ shows both majors.
2♥ shows hearts and a minor suit.
2♠ shows spades and a minor suit.
2NT shows both minors.
Three-level bids are natural and preemptive (weak).
(1) ♠A Q 9 5 2 ♥K J 10 4 3 ♦8 6 ♣3
Bid 2♦, showing both majors. Yes, you only have 10 high-card points, but the shapeliness of this hand makes it more valuable.
(2) ♠K J 9 4 3 ♥6 ♦K 7 ♣Q J 10 4 2
Bid 2♠, showing spades and a minor suit.
(3) ♠A 7 4 ♥K J 10 7 3 2 ♦8 ♣6 5 3
Bid 2♣ showing a one suiter. This hand has only 8 HCP and may not be worth much on defense, but it should be quite good on offense. Remember, your aim is to interfere with the opponents’ bidding.
(4) ♠7 4 ♥K Q J 10 7 4 2 ♦A Q 3 ♣A
Double. Do not bid 2♣ to show a one-suited hand. You are too strong. If you end up defending 1NT doubled, you can lead a heart and expect to take at least six hearts and two aces. If the opponents scramble to safety, you can next bid your hearts and partner will know you have a good hand and a good suit.
(5) ♠J 10 7 6 5 3 ♥K 9 2 ♦8 4 ♣6 2
Pass. True, you have a six-card spade suit, but this hand is too weak to compete. Do not bid 2♣ to show a one-suited hand.
When you fill out your convention card, don’t simply write “Cappelletti” or (worse) “Capp” on the convention card. Fill in what suits each bid shows on the appropriate line.
Notice that this defense (Cappelletti) against the opponents’ 1NT openings is listed under the heading “vs. Strong,” meaning that you play it only when the opponents use a 15–17 (or 16–18) 1NT range. If you play a different system against weak 1NT openings (such as 11–14 or 13–15 HCPs), write it in the adjacent column, and write the word “Weak” on the “vs” line.
