The trick in Poker is to play random. Try to refrain from any system or logical order in which you decide whether to play that particular hand. Let your system be as random as possible. Randomness is by far the worst adversary for any poker player. Randomness, in combination of course with the all known ‘poker face’, is a strong force and hard to play against. Players will never know what to expect and this will influence their style of play. They could become, for example, too ‘tight’ or too reckless. Then, if you get this tactic down, it might even demoralize the other players, because they simply do not know what to do.
