Recollect the Fundamental Theorem of Poker: Any time an opponent plays his hand incorrectly based on what you have, you have gained; and any time he plays his hand correctly based on what you have, you have lost. An opponent who knows you never bluff is much less likely to play his hand incorrectly. Any time you bet, he will know you are betting for value.

He will play only when he figures he has a better hand than yours or when he is getting sufficient pot odds to call with more cards to come. Bluffing, then, or the possibility that you might be bluffing, is another way of keeping your opponents guessing. Your occasional bluffs disguise not just the hands with which you are in fact bluffing but also your legitimate hands, with which your opponents know you might be bluffing.

To make sure we agree on what is meant by a bluff, we will define it as a bet or a raise with a hand which you do not think is the best hand. Secondly, within each of these categories, there is intuitive bluffing, which is the subject of this chapter, and mathematical bluffing, which will be discussed in the next chapter.
