It’s tempting to perform a kind of “profiling” simply from the way a player stacks his or her chips, which like other assumptions based on, say, clothing, appearance, or the player’s sex or age might indicate something meaningful about a person’s playing style.
Meanwhile others tend always to have a few strays laying around, or even have “dirty stacks” with chips of different denominations mixed together in a single column. Some players are very meticulous about lining up their stacks in perfectly constructed, uniform towers. There are varying degrees of tidiness displayed in chip stacking.
As a tournament reporter for many years, I’ve spent a lot of time eyeing players’ chip stacks, enough to develop all sorts of ideas and opinions about the significance (or lack thereof) of how a player chooses to stack his or her chips.
