RET'RO.OPPOSI.TIOI\J Retro-()pposition and Other Retro-Analytical Clhess Problems by T. R. Dawson G. P. "{elliss First Published August 1989 Reset February 1997 page I RETRO-OPPOSI'IION Qetro-Opposition and Other Retro-Analytical Chess Problems by T. R. Dawsor1 edited by G. P. Jelliss This booklet, containing; all of 'I'. R. Dawson's pioneering work on Reto-Opposifion, together with some of his best retro-analytical work of other types, is based on a small manuscript booklet, Seventy l,ive Retros by Dawson, dated Ist November 1928, found in the British Chess Problem Society Archive. ln its Introduction he wrote: "The 75 retrograde analyses in this collection comprise all the best of my published work in this field since the publication of Retrograde Analysis in 1915" and "ln the motto problems the foundations of the theory of retrograde opposition are laid and all the known types fully illustrated". Following the arrangement of the manuscript hooklet, the prohlems are given in cltronological order of composition (with one or two slight displacements). The bold-printed D-numbers are those assigned to his composifions by the composer himself, and the frst date quoted is that of composition. In some cases this date is mnny years before publication. An asterisk (+) attached to moves in the retro-opposition studies indicates the thematic tempo change.
