For decades Rodwell has been in a regular partnership with Jeff Meckstroth, and "Meckwell", for their surnames, is one of the most successful pairs of all time. They are well known for playing an aggressive and very detailed system called RM Precision (for Rodwell-Meckstroth), of which Rodwell is the principal theorist and author. Although he first learned basic Precision at the age of 14, he didn't get serious about developing his own version until 1982 after he and Meckstroth were already winning. Most of RM Precision was developed subsequently in the early '80s with adaptations following more slowly thereafter.The Bridge World, Volume 83, Number 4, January 2012, pages 26-31. Interview conducted in the fall of 2009 As a bidding theorist, Rodwell has created several conventions and methods including the support double, conventional transfers in many situations, the pass-double inversion and the serious three notrump. Although the Unusual Major Jumps Over One Diamond Opening convention (UMJOODO) is often credited to him, he denies inventing it.
