Acol Bridge

Acol is a bridge bidding system. It is named after a road in Hampstead, London, where there was a bridge club in which the system started to evolve in the 1930s. According to Terence Reese, its main devisers were Maurice Harrison-Gray, Jack Marx and S. J. Simon. Marx himself, writing in the Contract Bridge Journal in December, 1952, said: "...the Acol system was pieced together by Skid Simon and myself the best part of 20 years ago." The first book on the system was written by Ben Cohen and Terence Reese. Skid Simon explained the principles that lay behind the system, and the system was further popularised in Britain by Iain Macleod. The Acol system is continually evolving but the underlying principle is to keep the bidding as natural as possible. It is common in the British Commonwealth but rarely played in America.
