What Makes Him Tick?

Poker depends on your understanding your opponent. You've got to know what makes him tick. More importantly, you've got to know what makes him tick at the moment you're involved in a pot with him. What's his mood ... his feeling? What's his apparent psychological frame of mind right now? Is he in the Mood to gamble ... or is he just sitting there waiting for the nuts? Is he a loser and on tilt (playing far below his normal capability) ... or has he screwed down (despite his being loser) and begun playing his best possible game? Is he a cocky winner who's now playing carelessly and throwing off most of his winnings...or is he a winner who's started to play very tight so he can protect his gains?
