Card game.

Earlier this year I read "The Kite Runner" - not my usual sort of thing at all, but one of my grandchildren had to study it for GCSE so thought it might help.  There's a point in the book where the main character and his mate play cards.  And as I read, I thought "I know this game - or at least something very like it".  We used to play it in Germany - National Service.  We called it "Droog", but I've never heard of it since. Anyway my recollection is - standard pack of cards, each player is dealt five.  Next card is turned up to designate trump suit, and the rest form the stock pile.  Player to dealer's left starts. He can play one, three or five cards to the table.  If he plays three, two of them must be a pair.  If he plays five, four must be two pairs or four of a kind. Next player must now try and "kill" as many of the cards played as he can (or wants to).  You can kill a card by playing a higher one of the same suit, or a trump. A card which is killed, and the card that killed it are put to one side and play no further part in the game. Any card which the player is unable (or unwilling) to kill must be picked up and added to his hand.  If either player now has less than five cards (which the first one obviously must have), they must top up their hand to five from the stock pile - if there's any left.  If second player has killed all the cards, he then leads to the next hand by playing one, three or five to the table - if not, the next player in turn leads and and the game proceeds in the same way.  Object is to be first to get rid of all your cards.  We played for money of course - everybody anted into a pot which went to the winner.
