TO WIN OR NOT TO WIN

One of the most frequently encountered problems in bridge is knowing when to win, when to duck. A player may need to hold up a winner to hamper the enemy communications or concede a trick to facilitate his own. But there are no steadfast rules one can fall back on. Each deal
is different; so much depends on the particular setting.
In this book studying the example deals either as the declarer or a defender, the author explains not only when to win or duck, but also why one play is right and the other wrong depending on the circumstances.
