As new, but a few scuffs on cover Review by Tim Bourke:
A 16+pt 1C system with a 13 to 15 notrump and specialised suit openings from 1D to 2S, for example 1D promises either a one-suiter or a minor-two suiter while 1H promises a heart-minor based two suiter. The aim is to allow better description of distributions, something that Symmetric Relay achieves more efficiently in all respects.
