This is a very good book for beginners, describing the game and covering both the key aspects of both play and bidding well. Bidding methods are basic standard Acol, which is the standard system for either social or club bridge in the UK, so it means you can play them with any new partner. Selection of material is excellent - covers what beginners need to know without including non-essentials. Very clearly written in an easy to read style. Value for money is excellent as well. There are just a couple of key omissions - notably that he does not state that a double of 1NT is always for penalties, which is the exact opposite of the double of a suit bid for takeout, so could be costly! Nevertheless, definitely five stars. I would say this and Klinger's "Basic Bridge" Basic Bridge: The Guide to Good Acol Bidding & Play (Master Bridge Series)
are the two best books on bridge for beginners; the choice between them depends on style - Mendelson is a bit more chatty.
