<P> A thumb war (pea - knuckle or pea - knuckle war in New Zealand, and a "Guerre des pouces" in France) is a game played by two players in a tournament called a thumb - a-war (or thumb war) using the thumbs to simulate fighting . The object of the game is to pin the opponent's thumb, often to a count of three . The San Francisco Chronicle called the game "the miniature golf of martial sports ." </P> <P> The players face each other and each holds out their left hand or right hand in a "thumbs up", and they link hands such that each player's fingers curl around the other player's fingers . Gameplay has several tactics such as "playing possum", aiming for the knuckle rather than the nail for a pin, going for a quick strike, and waiting for one's opponent to tire . Variations include making the thumbs "bow", "kiss", or both before warring, and to war with both hands at once; or sneak attacks, which involve using your pointer finger to take over the opponent . Players may also engage in Rabbit Hole maneuver to escape imminent defeat . Players may not use any of the fingers except the thumb to pin down their opponent's thumb . This is when you duck your thumb down into your palm . </P> <P> The game is typically initiated with both the players uttering the rhyme "One, two, three, four, I declare a thumb war", passing their thumbs over each other in time with this rhyme . The rhyme is sometimes extended with "Five, six, seven, eight, try to keep your thumb straight ." or "Five, six, seven, eight . This should be a piece of cake ." In South America, the starting song is "ésta es la pulseada china" ("this is the Chinese arm wrestling"), with the same thumb dance as in English . </P> <P> Competitive matches on thumb wrestling have been held on Long Island and at Lowestoft . The 826 Valencia Foundation holds an annual thumb - wrestling competition, which has been won three times by San Francisco Chronicle book editor Oscar Villalon . There is no leaning nor tilting when thumb wrestling . </P>
