Kamikaze 1NT : ウィキペディア英語版 | Kamikaze 1NT
Kamikaze 1NT is a preemptive 1NT opening in the game of contract bridge and in common practice shows a balanced hand with 10-12 high-card points (HCP). It is used in first or second seat hoping to make 1NT opposite an average hand of about 10 HCP. Originally developed by John Kierein as part of a bidding system to indicate 9-12 HCP, he modified the point range to 10-13 HCP because American Contract Bridge League (ACBL) rules on conventions did not allow the use of Stayman on opening notrump bids with a lower limit below 10 HCP.〔 Common usage is with an upper limit of 12 HCP.〔 ==References==
