Note: Only the winners of each pool advance to the semifinals and have a chance at a medal. If you do not win the pool, you can at best place fifth.    48 kg/105.5 lbs.    This weight division has two tough pools, a solid pool and one rather easy one.    Pool 1 features two World champions, 2003 World Champion Chiharu Icho of Japan (who dropped down from 51 kg) and 2002 World Champion Brigitte Wagner of Germany. The third athlete in that pool, Canadian veteran Lyndsay Belisle, has been in the top four of the world. This is a rugged pool.    Pool 4 is also rough. Two-time World silver medalist Patricia Miranda of the USA has Li Hui of Japan in her pool, who was third in the 2003 World meet. Also in the pool Lorisa Oorzhak of Russia, a 2003 Junior World champion and 2004 Junior European champion. Rounding out the pool is Mayelis Caripa of Venezuela,     Pool 3 has four athletes, including three-time World Champion Irini Merlini of Ukraine. Her top challenger is probably Fani Psatha of Greece, who was fourth in the 2003 World meet. Lidya Karamachkova of Tajikistan earned her spot through the qualifiers, and Fadhila Louati of Tunisia is a wildcard.    Pool 2 features three wrestlers who did not place in the top five at last year's World meet. France had the No. 6 position in this division at the 2003 Worlds, and will enter Angelique Berthenet here. Enkhjargal Tsogbazar of Mongolia qualified through the Olympic qualifiers. Leopolina Ross of Guinea-Bissau is a wildcard.    The semifinals will feature Pool 1 vs. Pool 2, with the winner of Icho/Wagner/Belisle against the winner of the weakest pool. The semifinal match between Pool 3 and Pool 4 will have Irini Merlini of Ukraine as the favorite from Pool 3,  and the Miranda/Li/Oorzhak victor coming from Pool 4.    55 kg/121 lbs.     This weight class is actually pretty balanced between the pools.    Pool 1 has American newcomer Tela O'Donnell, who has not wrestled at the Senior World level before. Olga Smirnova of Russia was a World Champion way back in 1996, down at 110 pounds, and most recently was a European champion in 2002. Canada's Tonya Verbeek is a veteran, and has a win over O'Donnell from the Titan Games.    Pool 2 has three past World medallists. 2002 World bronze medalist Ida Theres Karlsson of Sweden is in this draw, as is another 2002 World bronze medalist from a higher weight division, Mabel Fonseca of Puerto Rico. Tatyana Lazareva of Ukraine was a World bronze medalist in 2001.    Pool 3 is strong. Two-time World Champion Saori Yoshida of Japan will be favored here. China's Sun Dongmei was fourth at the 2003 World Championships. Italy's Dilletta Giampiccolo was a 2001 World silver medalist up at 62 kg, and has been very tough since dropping in weight.    Pool 4 has one of the top veterans, four-time World champion Anna Gomis of France, who has not been a top star in recent season. 2002 World Champion Sofia Poumbouridou of Greece, who won her world title down at 51 kg, is in this draw. They will have Korea's Na Lae Lee in the pool, who won a gold at one of the Olympic qualifier events.    The semifinals will feature from Pool 1 the O'Donnell/Smirnova/Verbeek winner against the Lazareva/Karlsson/Fonseca winner. The bottom semifinal will have have Yoshida of Japan from Pool 3 (unless Sun or Giampiccolo upsets her) against the winner of the Gomis/Poumbouridou battle from Pool 4.    63 kg/138.75 lbs.    This is another division with some balance in the pool pairings. Two seem slightly less stringent than the other ones, but all of the pools have somebody of substance in the draw.    Pool 1 has one of the sport's veteran stars, two-time World champion Sara Erikson of Sweden. Her most recent medal was a World silver in 2002. Germany's Stephanie Gross has not been a World champion, but boasts four World medals from the late 1990s. The other person in the pool is Stavroula Zygouri of Greece, who only gets in because she is from the host nation.    Pool 2 is loaded. 2001 World champion Lili Meng of China will face 2003 World silver medalist Sara McMann of the United States and 2003 World bronze medalist Viola Yanik of Canada. McMann has beaten Yanik a number of times in recent seasons.    Pool 3 has one veteran star, Lise LeGrand of France, who won two World titles in the mid 1990's and was second in the 2002 World meet. Her two challengers, Natalya Ivanova of Tajikistan and Volha Khilko of Belarus, got in by placing third in Olympic qualifying events.    Pool 4 features the favorite at the division, two-time World champion Kaori Icho of Japan. There is another World champion in this draw. Alena Kartacheva of Russia was a 2002 World champion at 59 kg, and placed fifth in the world in 2003 at this division. Also in this pool is Lyudmila Golovchenko of Ukraine, fourth in the world last year.    The semifinals will feature Pool 1 winner Erikson or Gross against Pool 2 victor from Meng/McMann/Yanik. The bottom semifinal bracket will have whoever takes Pool 3 against either Icho or Kartacheva from Pool 4.    72 kg/158.5 lbs.    This division has two very tough pools on the bottom, and two other pools on the top that are not quite so loaded up.    Let's start on the bottom. Pool 3 has six-time World champion Christine Nordhagen of Canada, who made a comeback this year for a chance at an Olympic medal. China's Wang Xu, second and third at the last two World Championships, is a formidable force. The other qualifier, Katarzyna Juszczak of Italy, will have a tough time with these two stars.    Pool 4 has the toughest first-round match in the women's draw, five-time World Champion Kyoko Hamaguchi of Japan against two-time World silver medalist Toccara Montgomery of the United States. These two rivals have had many close battles. Also in this draw is Stanka Zlateva of Bulgaria, fourth in the 2004 World meet, who should have difficulties with these two stars.    The top of the bracket features Pool 1, where the best finisher from last year's World meet was Anita Schaetzle of Germany, who was fifth in New York. Gouzel Maniorova of Russia and Marina Gastl of Austria got into the tournament through the Olympic qualifying events.    Pool 2 has three other athletes who did not place in the top five at the 2003 World meet, the major qualifying event for the Olympics. Svitlana Sayenko of Ukraine and Burmaa Ochirbat of Mongolia got into the tournament through the Olympic qualifying tournaments. Maria Louiza Vyroni of Greece is in the draw because she is from the host nation.    The top semifinal from Pool 1 and Pool 2 will place an athlete in the gold-medal match who did not win a medal last year on the World level. Schaetzle and Maniorova from Pool 1 look to be favorites, and Sayenko and Ochirbat are contenders from Pool 2. The bottom bracket will have two strong past medallists, with Pool 3 favorites being Nordhagen or Wang, and Pool 4 being the winner of the Montgomery/Hamaguchi war.      This is an example of how the pool system sometimes overloads one side of the bracket, while giving a shot to some athletes on the other side who were not expected to be top medal contenders.
