Two gamblers at cards invite a foreigner to join them in the back room of a pub. They play pontoon and the exotic looking stranger, who speaks only English, keeps losing at first. His comment is that it's only a sport. Soon, the situation reverses. The younger of the two men is apparently an addicted gambler; he does not want to stop despite his friend's warnings, eventually losing his entire pay. He wants to get his money back by going for broke, but he cheats. The foreigner, it seems, has noticed nothing, but the older colleague of the younger card player strongly rebukes him and refuses to play this way. In the last game, the gambler has a blackjack - an ace and a ten. The foreigner, however, has two aces. The younger man tries to delude the foreigner by telling him that in the Czech version of the game, his hand is better. At that moment, the stranger, speaking rather fluent Czech, protests against the gambler's lies and leaves the room with all of the young man's money and a remark that it's only a sport.
