The Kamikaze No Trump is a bidding system devised by Mr. John Kierein. The concept was to open a holding in First or Second Seat with a total of 9 to 12 high card points. After the ACBL regulated that any No Trump opening with less than 10 high card points could not apply the usual conventions such as Stayman, Mr. John Kierein altered his Kamikaze No Trump opening to show values between 10 and 13 high card points.
