These opening bids were devised and developed by Mr. Robin Michaels of Cambridge, England. They employ the use of opening a 5-card Major suit, a weaker No Trump range, and a distributional description of the holding on the two level.

Note: The Imprecision Club opening bids should not be confused with the bridge players from the New York University, who call themselves the Imprecision Club, as reported in The New York Times by Mr. Alan Truscott in his bridge column of June 25, 1991.

Generally all first responses to a 1 Club opening bid are considered to be artificial in nature, but they also show strength whereas all responses to a 1 Diamond opening are based on the Precision bidding system, which uses the first response of 1 Heart as an artificial negative.

The designation means the quality of lacking precision, and may be considered as a pun of the more complex Precision bidding system.

Note: Any contributed information about the personality of Mr. Robin Michaels, especially photographic material, would be greatly appreciated.
