Super Gerber

Upon studying the concept of the Gerber Convention, it becomes quite evident to all bridge players, that the convention itself has one feature, which is lacking. The use of the 4 Clubs bid as Ace or Key Card-asking means that the 4 Clubs bid can not be used as a natural bid or as a cuebid. Super Gerber was devised to overcome this disadvantage. This Ace-asking conventional modification was devised by Mr. Robert Goldman.

Using Super Gerber, the bridge player can use any suit bid between 4 Clubs and 5 Clubs inclusive to ask for Aces.

Super Gerber can be applied in the bidding auction when both partners have agreed to play in a Minor suit, or when, in the bidding auction, the last bid is 3 No Trump. One of these two conditions must exist before Super Gerber takes effect.

After one partner has bid 3 No Trump or a Minor suit has been established as the trump suit, Super Gerber is initiated with a bid of four of the lowest unbid suit. The examples, which follow, should illustrate the use of the Super Gerber convention more than written explanations.

In the following example:

Opener Responder Meaning
1 1
3 NT 4 Lowest unbid suit equals Super Gerber.

4 Diamonds is the lowest unbid suit and is Super Gerber.

In the following example:

Opener Responder Meaning
1 1
3 NT 4 Lowest unbid suit equals Super Gerber.

4 Clubs is the lowest unbid suit and is Super Gerber.

In the following example:

Opener Responder Meaning
1 1
3 NT 4 Lowest unbid suit equals Super Gerber.
.

4 Diamonds is the lowest unbid suit and is Super Gerber.

In the first and last of the three examples, a rebid of 4 Clubs by the responder would be considered a natural bid.

 

In the following example:

Opener
Responder
Meaning
1
2
2
3
3 NT 4 A natural rebid.

the partnership agreement is that 4 Clubs is a natural bid, but in the next example:

Opener
Responder
Meaning
1
2
2
3
3 NT 5 This rebid now becomes Super Gerber.

the partnership agreement is that 5 Clubs is not a natural bid, but rather Super Gerber. This is obvious since the responder jumped one level to initiate Super Gerber.

 

When both partners agree on a Minor suit fit, Super Gerber can also be applied by bidding four of the lowest ranking unbid suit.

In the example:

Opener Responder Meaning
1 3
4 This rebid now becomes Super Gerber.

the 4 Diamond rebid by the opener is Super Gerber because it represents a jump bid in the lowest ranking unbid suit.

In the example:

Opener Responder Meaning
1 3
4 This rebid now becomes Super Gerber.

the 4 Hearts rebid is Super Gerber because it represents a jump bid in the lowest ranking unbid suit.

In the example:

Opener
Responder
Meaning
1
2
2 NT
3
4 This rebid now becomes Super Gerber.

the 4 Hearts rebid by the opener represents a jump bid in the lowest ranking unbid suit, and is therefore Super Gerber.

 

By using a series of Step Responses, the number of Aces can be determined.

First Step shows:
0 or 4 Aces
Second Step shows:
1 Ace
Third Step shows:
2 Aces
Fourth Step shows:
3 Aces

 

As with the Blackwood Convention, the Super Gerber convention can be used also to ask for the number of Kings by rebidding the Super Gerber suit.

In the following example:

Opener Meaning Responder Meaning
1 2 Jump Shift
2 NT 3
4 Super Gerber 5 Third Step showing 2 Aces
5 Asking for Kings

the 5 Hearts rebid of the Super Gerber suit, which is Hearts, is asking for the number of Kings. The responses are the same as the Step responses for Aces, only one level higher.

As with all other conventions, the Super Gerber convention has its flaws, especially when all suits have been bid. Under these circumstances, the partnership agreement is that a bid of 5 Clubs is then Super Gerber. However, if one partner decides to ask for Kings, then the bid is 6 Clubs. This leads to a certain ambiguity, and the partnership agreement may not be clear. There must be a partnership understanding regarding this situation.

Whatever the partnership understanding is concerning the possible ambiguity of bids under certain circumstances, a Partnership Agreement should be reached, in order that no confusion arises. If the partnership prefers to include Super Gerber in its partnership agreement, then this should be made known to the opponents at the bridge table in the appropriate manner.

 

 

If you wish to include this feature, or any other feature, of the game of bridge in your partnership agreement, then please make certain that the concept is understood by both partners. Be aware whether or not the feature is alertable or not and whether an announcement should or must be made. Check with the governing body and/or the bridge district and/or the bridge unit prior to the game to establish the guidelines applied. Please include the particular feature on your convention card in order that your opponents are also aware of this feature during the bidding process, since this information must be made known to them according to the Laws of Duplicate Contract Bridge. We do not always include the procedure regarding Alerts and/or Announcements, since these regulations are changed and revised during time by the governing body. It is our intention only to present the information as concisely and as accurately as possible.
