BROZEL CONVENTION

This is a conventional method with the purpose of defending against a 1 No Trump opening generally with a range of 15-17 points. The Brozel convention was developed by Mr. Bernard Zeller of New Jersey, United States, and can be applied either in the direct or balancing position.

The Brozel convention is a system of bids to describe a two-suited hand. Distribution of the hand bidding Brozel is the key to a successful contract. Similar to the Pinpoint Astro, it however places emphasis on Hearts.

However, a Double promises a one-suited holding with at least a 6-card unspecified suit. If the partner holds some values and wishes to compete, the partner will use the Relay bid of 2 Clubs allowing the Doubler to show his suit. Once the Doubler has shown his suit, the partner will generally pass. If the Doubler passes the 2 Clubs bid, then the Club suit is his suit.

The following schematic outlines the overcalls and the responses of the advancer:

Overcaller Meaning Advancer Meaning

2 :

shows Clubs and Hearts Pass / 2 If there is a Club fit and advancer has weak values, then the advancer passes. If there is no fit and advancer has weak values, then the advancer corrects on the same level to the Heart suit.

2 :

shows Diamonds and Hearts Pass / 2 If there is a Diamond fit and advancer has weak values, then the advancer passes. If there is no fit and advancer has weak values, then the advancer corrects on the same level to the Heart suit.

2 :

shows Hearts and Spades Pass / 2 If there is a Heart fit and advancer has weak values, then the advancer passes. If there is no fit and advancer has weak values, then the advancer corrects on the same level to the Spade suit.

2 :

shows Spades and a Minor Suit Pass If there is a fit and advancer has weak values, then pass is the correct response.
2NT Asks for the Minor suit. Implies no support for Spades.

2 NT:

shows both Minor Suits 2 / 2 The advancer bids his better Minor suit.
Double: shows a 6-card plus suit Pass The advance may pass the double if holding sufficient values. The double is converted to a Penalty Double. Otherwise the advancer makes the lowest possible bid.
3 : shows a three-suited holding with either a void or singleton in Clubs and at least 4-card support in each of the unbid suits 3 / 3 / 3 The advancer bids his best suit in the unnamed suits and establishes the final contract.
3 : shows a three-suited holding with either a void or singleton in Diamonds and at least 4-card support in each of the unbid suits 3 / 3 / 4 The advancer bids his best suit in the unnamed suits and establishes the final contract.
3 : shows a three-suited holding with either a void or singleton in Hearts and at least 4-card support in each of the unbid suits 3 / 4 / 4 The advancer bids his best suit in the unnamed suits and establishes the final contract.
3 : shows a three-suited holding with either a void or singleton in Spades and at least 4-card support in each of the unbid suits 4 / 4 / 4 The advancer bids his best suit in the unnamed suits and establishes the final contract.

Since the Brozel convention is so flexible, two-suited hands can also be shown even after the partner of the 1 No Trump bidder has made a weak response. Whatever the responder of the 1 No Trump bidder bids, the Brozel bid indicates that suit and the next higher unbid suit.

By a Three-Suited Hand, after a 1 No Trump opening as a direct call or in the balancing seat, the Brozel bidder would jump to the three level, not only showing good distribution and a void but also sufficient strength. For example, the Brozel bidder has the following holding:
AJ109
KQ87
AJ963

The Brozel bidder would bid 3 Hearts over the 1 No Trump opening or in the balancing position. His partner is expected to set the final contract.

If the responder of the 1 No Trump opener has made a weak response, the Brozel bidder can bid 2 No Trump showing a three-suited holding with adequate strength. A cuebid of the bid of the responder indicates a three-suited holding, but suggests a stronger hand.

Using the Brozel convention, the Brozel bidder can also double, showing a one-suited hand. His partner may pass with very few values. If his partner, however, wishes to enter the bidding, he will use a Relay bid to discover the long suit of his partner.

The flexibility of the Brozel convention is complex, but whoever masters it can use it quite effectively. However, if the Partnership Agreement is not that solid, then the suggestion is made to avoid this bidding method because of its complexity.

As a variation on this concept Mr. Lionel Wright, mainly of Auckland, New Zealand, proposed and developed bids, which could be employed against strong and weaker No Trump openings, not only for the 15-17 point range. In essence, the bids are identical to the original version of Mr. Bernard Zeller except for four bids, which are shown below as well as the responses of the advancer after a double by the intervenor:
Intervenor: Meaning
Double: Promises at least a 4-card Spade suit plus a longer unspecified suit.

2 :

Promises at least a 5-card suit plus in Hearts.

2 :

Promises at least a 5-card suit plus in Spades.

2NT:

shows a fit for Spades and is invitational.
Advancer: Responses after a Double by Intervenor

2 :

Indicates strongly a misfit for Spades. The intervenor either passes the Diamonds relay of advancer or corrects.

2 :
