When lawyers, doctors and captains of industry step into the boxing ring, they like to mix it up a little, sometimes in front of ticket-buying friends and family.

They’re not overly fond, though, of lost fights, black eyes or getting knocked cold. And since they pay for the privilege, white-collar boxing has evolved to limit such unpleasantness with short bouts and referees quick to intervene. Often there’s no decision. Everybody’s a winner.
