Mr. Ira G. Corn Jr. of Dallas, Texas, had a goal and that was to reclaim the World Team Championship Title to the United States. With his financial aid, he formed a group of professional bridge experts, purchased a set of computers, and developed the Aces Scientific System.

Mr. Ira Corn, born in the year 1921 and died in the year 1982, of Dallas, Texas, United States, was elected to the Hall of Fame by the American Contract Bridge League in the year 2002.

Biographical Information

Mr. Robert Goldman, born in the year 1938 and died in the year 1999, of Highland Village, Texas, United States, acted as perhaps the chief designer. Mr. Robert, (aka Bobby), Goldman published the book in 1978: Aces Scientific System. The picture of Mr. Robert Goldman is also from the year 1978.

Note: Of historical note and value is the fact that Mr. Ira G. Corn Jr. was one of the first members of the international bridge community to realize the importance of and employ the use of the computer to analyze the frequency of certain bidding sequences, calculate the successful percentages of bidding techniques, and then complete the compilation of a computer-based bidding system. As a result the Aces Team was victorious in the years 1970 and 1971, in which the Aces Team won the Bermuda Bowl international competition.


With the aid of the computers, this group of bridge experts fed almost every conceivable and possible card combination into the computer, and examined and analyzed the result. At the end of this procedure, the Aces Scientific System was born. For every card combination held there were precise bidding standards, even for those situations when the opponents decided to enter the auction with either a call or a bid.

A few examples for a situation in the game of bridge follow. A situation is any call or bid which conveys information.

Pass = a situation
1 = a situation
1 = a situation
1 - 1 = a situation
1 - 2 - Double = a situation

For all of these situations, the computer recommended certain precise and detailed bidding methods. These situations had to be recognized by the bridge players and applied at the correct time, almost scientifically.

Although this system had several strong similarities with Standard American, the deviations are quite noticeable.

* As part of the Aces Scientific System, the method of Unbalanced Swiss Raise was used.

Following an opening in a Major suit, the responder has several options for game-forcing raises. A jump response on the three level of the other Major suit shows 10 to 12 points with an unidentified singleton. The first response of 3 No Trump promised 13 to 15 points and an unidentified singleton.

The opener uses the cheapest rebid in order to locate the singleton.

The responder can follow several step patterns to show his singleton. One step pattern is natural and shows a singleton in the suit responder rebids. A second step pattern is to rebid 3 No Trump to show a singleton in the remaining unbid suit. A third step pattern is to rebid four of the anchor suit to show his singleton.

** Also as part of the Aces Scientific System, the method of Value Swiss Raises was used.

Value Swiss Raises are employed to show a range of forcing balancing raises as responses to an opening of a Major suit. These Value Swiss Raises communicate detailed information such as no singleton, a good 5-card suit, and show either a 4-card support for the opener or a 3-card support with two of the top honors for the opener. The chart below shows the point range

Opener   Responder   Range
1 or 1   1 NT   Forcing
Rebid   4 or 4   Shows 12-13 points.
    4   Shows 12-14 points.
    4   Shows 14-16 points. This first response can be the Swiss conventional response methods and/or any variation thereof.
    2 NT strong   Shows 16-18 points.

The Aces Scientific System includes several slam bidding conventions. Among them are the elements of Roman, Blackwood, Gerber, and Super Gerber.

The Aces Scientific System was used with good success, placing among the top three contenders. In 1969, the Aces Team, as it became to be known, won the Spingold Knockout Teams, and in 1970 and 1971 won the Bermuda Bowl for North America. Although the Aces Team continued their success, the team gradually dissolved around the year 1983.
