Revolving discard system

Whats the simplest Discard system

Revolving Discard System

With the Revolving discard System you have the possibility to request suit preference in two ways
A low ( 5 or below) discard indicates interest in the suit directly below (a low club however signals spades); a high discard(7 or above) signals preference for the suit directly above (a high spade signals clubs). In a suit contract, the trump suit is omitted in the signal. This system is regarded by many to be easier to remember and use than the Lavinthal Discard System.
