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.
