[1] The central feature of the Precision system is that an opening bid of one club is used for any hand with 16 or more high card points (HCP), regardless of distribution.
Today, multiple world champions Jeff Meckstroth and Eric Rodwell play their own variant known as RM Precision.
Because all opening bids except 1♣ are limited, the responder almost immediately knows the hand potential and the chances for a part score, game or slam.
This is so absurd that I wish to go on record in stating that the Big Club cannot be played with any hope of success if you attempt to use it by bidding only 5-card majors.My opinion on Precision is that combining five-card majors with a forcing club is like trying to mix oil and water, and it has serious structural defects…"The main disadvantage of the strong-club system is its vulnerability to preemptive bids.
When 1♣ – 1♦ is no longer a 4–4–4–1, 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.
RM Precision is a bidding system played by Eric Rodwell and Jeff Meckstroth (which we will call Meckwell) – one of the most successful bridge partnerships of all time.
