Precision Today
There have been many variations since 1969's 'Precision Club'. 3NT is played as 'Gambling' (where it used to show 24-27HCP), 1♣ - 1♦ is not anymore a 4-4-4-1 (Impossible Negative), and the "Unusual Positive" is used instead.
When 1♣ - 1♦ is not anymore a 4-4-4-1,
1♣ - 2♥ = 8+ HCP, 4-4-4-1 Singleton ♠;
1♣ - 2♠ = 8+ HCP, 4-4-4-1 Singleton ♣;
1♣ - 3♣ = 8+ HCP, 4-4-4-1 Singleton ♦;
1♣ - 3♦ = 8+ HCP, 4-4-4-1 Singleton ♥
Also, modern Precision often uses relay bids or transfer responses to 1♣ to both try to make the strong hand declarer and saving space in the auction. Other popular Precison variations on opening bids are using a strong 1NT (14-16 is most common), using 2♣ to show only a 6+ club suit and expanding the possible hand patterns for the 2♦ bid to include the usual 4-4-1-4 and 4-4-0-5 as well as 4-3-1-5 and 3-4-1-5.

Famous quotes containing the words precision and/or today:
“We are often struck by the force and precision of style to which hard-working men, unpracticed in writing, easily attain when required to make the effort. As if plainness and vigor and sincerity, the ornaments of style, were better learned on the farm and in the workshop than in the schools. The sentences written by such rude hands are nervous and tough, like hardened thongs, the sinews of the deer, or the roots of the pine.”
—Henry David Thoreau (1817–1862)
“Working women today are trying to achieve in the work world what men have achieved all along—but men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its toll—on women, on men, and on our children.”
—Jeanne Elium (20th century)
