Les enchères au bridge - exercices pratiques

Problème 1

Meilleure réponse:

Main 1

b) 4♣

With a good seven-card suit, it would be overly cautious to pass. 3NT has the merit of showing the Spade stopper, but may be wrong when partner has no fit in Clubs or when the Hearts are wide open. 4♣ shows the extra length in the suit and keeps your options open.

Problème 2

Meilleure réponse:

Main 2

b) 3NT

You might bid 3♠ with fewer high cards. Doubling without four Hearts is also a problem. With ♣A10 as a stopper, even if partner can offer no help in the suit, holding up once might take East out of the game.

Problème 3

Meilleure réponse:

Main 3

b) Pass

Overcalling 3♠ with a modest five-card suit is hardly risk free. Doubling gets the Spades into the picture but the shape is not ideal. Passing is the soundest action, hoping partner may be able to make a useful contribution.

Problème 4

Meilleure réponse:

Main 4

c) Pass

Doubling without four Hearts is dubious. 3NT is a little light on points, but not a bad choice. Passing is again the wisest option, hoping partner will have something to say.

Problème 5

Meilleure réponse:

Main 5

b) 4NT

A raise to game is too conservative. A cue bid of 5♦ shows the Heart support and Diamond control but leaves partner in the dark about the Club control. 4NT asking for keycards is not risk free, but may tell you everything you need to know.

Problème 6

Meilleure réponse:

Main 6

a) Dbl

With support for all the unbid suits, 4♠ is too unilateral. Bidding 5♦ is a possibility but takes away a lot of space. Doubling is the most flexible option.

Problème 7

Meilleure réponse:

Main 7

b) 3♦

Partner having already passed means you can expect a hand which is likely to be close to an opening bid with reasonable shape. Passing or bidding 3NT would be reasonable if you need a good result but 3♦ is the down the middle approach.

Problème 8

Meilleure réponse:

Main 8

a) 6♠

The opponents’ bidding suggests that partner will have at most a singleton Heart thereby increasing the likely hood that South’s hand will have some support for Spades. 4♥ is too cautious. Bidding 5♥ is the scientific move, but the practical approach is to jump to slam.
