Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In poker, the strength of a hand (how likely it is to be the best according to the rules of the game being played) is often called its value; however, in the context of poker strategy the term is more often used to describe a betting tactic, a bet for value. This bet (or raise) is intended to increase the size of the pot, by inducing opponents to call. A bet for value is in contrast to a bluff or a protection bet (though some bets may have a combination of these motives).
