Everest, as it turns out, is a sophisticated poker cheat. His preferred cheating method is collusion with hired partners (Everest calls them his "horses") at the same table, who signal their hole cards to Everest by flashing subtle hand signs. Toward the end of the series, during the "World Championship of Poker" tournament, Everest's horses also help him advance in the tournament by accumulating chips during their own play, then "dumping" them to Everest by intentionally losing to him and passing them during breaks. Everest runs his cheating racket in much the same manner as a Mafia boss, treating his loyal partners lavishly but also coming down brutally on those who violate his trust (up to and including murder, thus giving his "Matador" nickname a whole new literal meaning), and bribing Colorado Casino officials and even local law enforcement to turn a blind eye toward his illegal activities.
