The concept is attributed to Mr. Mark David Feldman, a bidding player and bridge theorist. He was born in the year 1951 and is of New York City, New York, United States. He is also the originator of a defense methiod to a strong Club opening, devised in the year 1971 at the age of twenty years old known as SCREW.

This defense method later became more popularly known as CRASH. In the year 1975 he developed the treatment of a jump fo four of a Minor suit over an opposing Major suit Weak Two bid to show the bid Minor suit and the other Major suit.

This is a method whereby the player makes a jump to four of a Minor suit over an opposing Major suit Weak Two bid, and sometimes preempts on the three level, to show a two-suiter, generally a 5-5 distribution, in the suit bid and the unbid Major suit and/or one still unknown and unspecified Major suit, depending on whether the Weak Two bid and/or Preempt is a Minor or Major suit.

However, if the two suits are different in length, then the assumed longer suit is the Minor suit as in a 5-6 distribution. The so-called leap is not forcing so one would expect opening bid strength, but rather distributional features. Not to be confused with Super Michaels. As a defense against a preempt on the three level, the following example is offered from the Bermuda Bowl 2000 tournament.

East, Mr. Wilkosz, opens the auction with: 3 Clubs. Mrs. Sandy Low overcalls with: 4 Diamonds explained as showing at least a 5-card Diamond suit and an unspecified Major suit, also of 5-card length. Leaping Michaels. West passes and North raises to 6 Diamonds. The result was down one, but review showed that had Mrs. Sandy Low played for the singleton King of Diamonds, she would have taken all thirteen tricks.

Overcall Method Summary

The following is an outline of the possible overcalls and the definitions assigned to each overcall.
