This variation of the Crash conventional method is attributed to Mr. Roberto Scaramuzzi, (Department of Mathematics, Louisiana State University) which has not been substantiated, only mentioned and uploaded to a chat board on February 1, 1995. The overcalls are as follows and all bids are employed only after an opponent has opened the auction with 1 No Trump, range 15-17 points:
Double: Promises two suits of the same color - either Red suits or Black suits. 2 :
Promises two suits of the same rank - either both Major suits or both Minor suits. 2 :
Promises two suits of the same shape - either Diamonds and Spades or Clubs and Hearts. 2 :
A natural bid showing Hearts. 2 :
A natural bid showing Spades. 3 :
A natural bid showing Clubs. 3 :
A natural bid showing Diamonds.
Note: This conventional method is presently illegal under the revised ACBL Convention Chart. It is only archived here as part of the history of the game of bridge. Compare with the original convertional defense method as devised by Mr. Kit Woolsey and Mr. Steve Robinson.
A second variation contributed, also February 1, 1995, by Mr. Roberto Scaramuzzi, follows. It has no designation but it is based on the original concept of Mr. Kit Woolsey. The overcalls are as follows and all bids are employed only after an opponent has opened the auction with 1 No Trump, range 15-17 points.

Double: A mystery 4-card Major, and a mystery 5-card plus Minor. After you play this for a while, you can use the Tuna-fish variation: you also double with a decent 1-suiter in one of the minors) Responder or Advancer: 2 . Pass if your Minor is Clubs; correct if your Minor is Diamonds.
Responder or Advancer: 2 : Asks doubler to bid his Major.
Responder or Advancer: 2 or 2
are natural responses.
2 :
Both majors (with equal length in the Majors; advancer can bid 2 to ask overcaller to pick).
2 :
A one-suiter in one of the Majors. 2 :
At least five cards in that major, and a side minor suit. 2 :
At least five cards in that major, and a side minor suit. 3 :
A natural bid. 3 :
A natural bid.
Note: Mr. Kit Woolsey makes it much easier to find your best combined fit. Against that you sometimes end up at the three-level, and if the opponents bid over the double, it may be hard to compete, since doubler's suits are not known.
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.
