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:
“Concision in style, precision in thought, decision in life.”
—Victor Hugo (1802–1885)
“As yesterday and the historical ages are past, as the work of today is present, so some flitting perspectives and demi-experiences of the life that is in nature are in time veritably future, or rather outside of time, perennial, young, divine, in the wind and rain which never die.”
—Henry David Thoreau (1817–1862)
