Very rarely is stacking chips used as a ploy by a player. Glimpses of an opponent's true nature can often be gained by watching the way he stacks his chips. The very organized manner in which these chips are arranged suggests that this player will probably choose his hands carefully, seldom bluff and won't display a lot of gamble. Of course his mood may change during the game, but in that case his stacks will probably become less neatly arranged. There may even be a few extra chips of varying value placed on top of the player's large stacks of chips. This could be his profit. That's important to know, because you can frequently bluff successfully just by betting slightly more than a player's profit.
