A transposition in chess is a little like a bait-and-switch marketing ploy. The customer thinks he8217;s getting a bargain on one piece of merchandise, but he ends up buying another at a much higher price. In the first book devoted to chess transpositions, New York Post columnist and acclaimed chess author Andy Soltis shows how this strategy works over the board. By transposing a series of well-known moves (i.e., making them in an unfamiliar order), a player leads his opponent into an unfavorable position that he would normally have shunned. Using entertaining examples from the games of the masters, Soltis covers a variety of transpositions in virtually every kind of opening: double e-pawn, Sicilian, the Reti, English, Indian, and others.
