Chilli bidding system by Alan Williams

EHAA or Every Hand An Adventure.From the late 50’s.
Agressive, natural style of bidding that combines mini notrump openings, wide-range weak two-bids, and a Goren-like four-card major approach into an easy, effective, and fun way to bid. It is not a highly specified system, but rather, like Standard American or Acol, a general style which can be played in numerous variations. Quoted from Eric Landau.

Precision System

Precision Club invented by CC Wei, a Chinese businessman, in the late 1960s

Precision Club, most common system used in the USA after Standard American and Two Over One first used on the international stage by the Taiwan national team in 1970. Following their success using the system in the 1970 and 1971 Bermuda Bowls, Precision exploded onto the world stage when the legendary Italian Blue Team adopted and refined it as Super-Precision. The Blue Team’s successes during the 1970’s using Precision brought the system prominence and prestige. Although its global popularity will never rival that of Standard American, 2-Over-1 or ACOL, it is generally reckoned to be more efficient that any of them and is the foremost Strong Club system in use today. Many modern experts, including multiple World Champions Jeff Meckstroff and Eric Rodwell use it as the basis of their system ….. from Oliver Clarke Precision Club page
