Beggar-my-neighbour

Beggar-my-neighbour is a card game. It is played by two players and the cards are divided between them. Each of the player tries to acquire the opponent's cards. They alternately turn cards up, and if an honour is revealed, the other player must find an honour, but in specified number of turns, or else the played cards are forfeited.

Beggar-my-neighbour is also a term that refers to a policy, especially a national policy, of self-aggrandizement at the expense of competitor countries.
