MODIFIED CANSINO
The origin of this variation of the Cansino convention is unknown. The original defense convention is attributed to Mr. Jonathan Cansino and Mr. Jeremy Flint, both of England, during the 1960s, and who were also instrumental in devising the Multi 2 used in the Blue Club System.
This variation is also a defense method used after the opponents have opened a 1 No Trump, especially against a weak No Trump opening with 12 to 14 high card points or even a No Trump range of 10-12 high card points. This idea is to discover, as soon as possible, a 7-card fit at least in one of the four suits, and preferably an 8-card fit.
The guidelines for this variation designated as Modified Cansino are as follows, and differ from the original concept in only several features. Source is: David Stevenson.
Opener Overcaller Meaning 1 NT Double Penalty Double. Partner must pass. 2 Promises Clubs and two higher-ranking suits: /

2 Promises Diamonds, Hearts and Spades; a three-suited holding such as 4-4-4-1 or 4-4-5-0. 2 A natural bid with a long Heart suit. 2 A natural bid with a long Spade suit. 2 NT A game-forcing bid with a two-suited holding in both Minor suits. 3 A natural and preemptive overcall meaning long Clubs. 3 A natural and preemptive overcall meaning long Diamonds.
Any suit bid higher than 3 Diamonds is not employed for showing a stronger holding as in the original concept, which is also an extension / evolution of the original concept. These features may be added at the discretion of the inidividual partnership and become part of the agreement.
