    Chess is one of the oldest board games in the world. A version of the game was first played in India in the sixth century. Throughout time, the game has been played by kings, knights, and generals who warned to prove their military skills and practice war strategies.

Today，the game is played by millions of ordinary people as well. Most play for fun,but there are players who compete seriously and have gone on to gain the rank of grandmaster -the highest rank a player can achieve.

In 1991, when Hungarian Judit Polgar achieve the rank of grandmaster, it caused quite an uproar (骚动）. First of all, Polgar is a female playing in a sport traditionally dominated by men. Also, Polgar was only 15 years old, making her the youngest in history at the time. In 1993, she defeated former world champion Boris Spassky in Budapest, Hungary. In 1998, she became the first woman in history to win the U. S, Open Chess Championship, which was held in Kailua-Kona，Hawaii.

Like her two older sisters, Polgar was strictly trained to be a master chess player as a young girl. She was homeschooled in all her subjects and played chess several hours every day. At the age of five, she was beating her father at the game. At eight years old，she was competing internationally. At the age of nine，she competed in and won the New York Open Chess tournament，placing first among unranked players. The young Polgar was just getting started.

Known for her fiercely competitive nature and ability to understand her opponents strategy early in a game, Polgar quickly won the respect of both fans and fellow chess players. Despite her achievements and clear talent, she often had trouble getting into top competitive situations because many of them didn’t include women. Polgar wanted to compete with the best一to be a world champion and not just a female champion. For this reason, she absolutely refused to play in women-only competitions. Her refusal paved the way for the next generation of female chess players.
