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.
There are varying degrees of tidiness displayed in chip stacking. Some players are very meticulous about lining up their stacks in perfectly constructed, uniform towers. 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.
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.
