Note: An athlete must win the pool competition in order to advance into the championship bracket and remain eligible for a medal.     55 kg/121 lbs.    This weight class has a pretty good spread of talent across the different pools. A few of the pools are tougher than others, and one pool is a bit weaker. However, considering the blind draw, this weight class has some balance.    Pool 1 is the loaded one, and it features American Stephen Abas, who was fifth in the 2003 World Championships. Also in this pool is Cuba's Rene Montero, the 2002 World champion, and 2003 World silver medalist Ghenadie Tulbea of Moldova. Abas has beaten Montero in the past. At last year's World meet in New York, it was Tulbea who beat Abas by a 10-8 margin. This will be a war, but Abas won the toughest pool in his weight last year in New York as well.    The other tough pool is Pool 7, which features past World champion Harun Dogan of Turkey, who returns from a doping suspension and has dropped a weight class. Dogan was a 1999 World champion up at 58 kg, and added a World title in 2002 at 60 kg. However, Dogan tested positive in 2002 and had that title taken away. The other star in the pool is 2000 Olympic bronze medalist Amiran Karntanov of Greece, who will get a great boost from the loud Greek crowds here. The others in the pool are 2004 European champion Martin Berberyan of Armenia, and wildcard O Song Nam of North Korea. This will be a tremendous battle.    Pool 5 is also pretty good. It features 2001 World Champion Herman Kontoyev of Belarus and two-time World bronze medalist Oleksandr Zakharuk of Ukraine. The other athlete, Kazakhstan's Bauyrzhan Orazgaliyev has his hands full here.    The weak pool is Pool 2, with nobody in the draw with major achievements. This features Velikov Radoslav of Bulgaria, Shaun Williams of South Africa and Li Zhengyu of China. U.S. fans may remember that Williams competed at the Univ. of Oregon. The winner has the rough prospect of facing the talented winner of Pool 1.    The rest of the pools follow.    Pool 3 is led by 2001 World silver medalist Babak Nourzad of Iran. His rivals will be Mongolia's Naranbaatar Bayaraa and Korea's Kim Hyo Sub.    Pool 4 has 2000 Olympic champion and 1996 Olympic silver medalist Namig Abdullayev of Azerbaijan in the draw, along with Japan's Chikara Tanabe and India's Yogeshwar Dutt.    Pool 6 has another past World champion, with 2003 World champion Dilshod Mansurov of Uzbekistan as the top person in the draw. The tough Russian, Mavlet Batirov, is also here, and a wildcard from Afghanistan, Bahir Ahmad Rahmati, is also in this pool.    There will be a few good battles in the pools here, but with a decent spread of talent, the quarterfinals and semifinals should be outstanding.    66 kg/145.5 lbs.    This division features a few tougher pools and a few less strenuous pools. One of the reasons is that there are a few big-time stars here, and the rest of the field is still proving itself. The Olympic Games is a great time for young stars to emerge, and this weight may feature a few.    The big name stars are spread apart.    Pool 2 features two-time World champion and Olympic silver medalist Serafim Barzakov of Bulgaria, who was also second at the 2003 World Championships. His pool has Evan MacDonald of Canada, who was eighth in the 2003 World meet, and Leonid Spiridonov of Kazakhstan, who won an Olympic Qualification Tournament.    Pool 4 has three-time World champion Elbrus Tedeev of Ukraine featured in the draw. His top challenge should come from tough Serguei Rondon of Cuba, who was fourth in the 2004 World Championships, plus Georgia's Otar Tushishvili, who was fifth in the 2003 World meet. This will be a rugged test for sure.    Pool 6 has 2000 Olympic champion and 1998 World champion Ali Reza Dabir of Iran. He comes off a tough year, not placing in the 2003 World meet in New York, and placing fifth in one of the Olympic Qualifiers. His draw is tough, with 2004 European champion Makhach Murtazaliev of Russia his opponent. Murtazaliev made the Russian team ahead of 2003 World champion Irbek Farniev, making him a top favorite here. The other in the pool is Artur Tavkazakhov of Uzbekistan.    U.S. fans will be excited about Jamill Kelly's draw in Pool 7. He has two opponents, Ruslan Bodisteanu of Romania, who was 11th in New York's World meet, and Elman Asgarov of Azerbaijain, who qualified through an Olympic qualifier. If Kelly wins his pool, he goes immediately into the semifinals, by the chance that he drew the bottom pool. His road to a gold medal would be four matches, instead of the five for other athletes in the pool.    The other three pools are not very challenging, in comparison to some of the others.    Pool 1 has Japan's Kazuhiko Ikematsu, who was a 2003 World bronze medalist. The others in the draw are Korea's Baek Jin Kuk, as well as wildcard Fred Jessey of Nigeria.    Pool 3 has host Greece's entry, Apostolos Taskoudis, plus Armenia's Zhirayr Hovhannisyan and India's Kumar Ramesh. Hovhannisyan won a gold medal at one of the Olympic Qualification Tournaments,  and was fifth in the 2000 Olympics.    Pool 5 features veteran Gabor Hatos of Hungary and Stefan Fernyak of Slovakia, who placed ninth and 10th respectively at the World Championships last year. Omer Kubucki of Turkey rounds out this pairing.    This weight class is wide open, especially if some established stars get eliminated in the tougher pools. Expect some interesting new faces to emerge, if not in the medals, at least to set up the next Olympic cycle.    84 kg/185 lbs.    The three top stars in this weight class are spread far enough apart that we may see some great late action if they can survive the pool draw.    2003 World champion Sajid Sajidov of Russia drew into pool 7, and has four athletes to battle. Veteran Nicolae Ghita of Romania is perhaps the most experienced of the group. Shamil Aliev of Tajikistan and Matar Sene of Senegal complete the pool. If Sajidov wins this, as expected, he moves right into the semifinals.    1999 World champion and 2000 Olympic silver medalist Yoel Romero has been placed in Pool 4. His draw is not difficult at all. Davyd Bichinashvili of Germany, who won an Olympic Qualifier meet, and wildcard Jeffrey Cobb of Guam are his opponents.    2003 World silver medalist Cael Sanderson of the United States had a competitive draw in Pool 2. The athletes who placed fourth in the World at his weight in 2003, Siarhei Borchanka of Belarus and fifth in the World at the division there, Magomed Kurguliyev of Kazakhstan, are his pool opponents.    Pool 6 is strong, with 2000 Olympic silver medalist Moon Eui Jae of Korea, and 2000 Olympic bronze medalist Mogomed Ibragimov of Macedonia in the draw, along with Gotcha Miroslav of Bulgaria.    There is at least one strong contender in each of the other pools.    Pool 1 features 2002 World bronze medalist Majid Khodaei of Iran is the top athlete, and his opponents are Kumar Anuj of India and Hideakazu Yokoyama of Japan.    Pool 3 has the 2003 World bronze medalist Revaz Mindorashvili of Georgia featured. He will face the host favorite, Lazaros Loizidis of Greece, and Vincent Akesse Aka of France.    Pool 5 is probably the least strong, with Gokhan Yavaser of Turkey, seventh in the 2003 Worlds, and Mamed Agaev of Armenia, seventh in the 2003 Worlds, as the top entries. They will also have Taras Danko of Ukraine in the draw.    120 kg/264.5 lbs.     Once again, the blind draw did a pretty good job of spreading apart the star athletes. If things hold to form, the top names in this division will not meet until after the pools are completed, something that should make wrestling fans pleased.    We will go in pool order in this preview.    Pool 1 features 2003 World champion Artur Taymazov, the 2000 Olympic silver medalist who is one of the top favorites. Also in this pool is 1998 World silver medalist Marek Garmulewicz of Poland, who made his name at 100 kg, and has not yet become a top super heavyweight. Palwinder Singh Cheema of India is also in this pool.    Pool 2 has a 1997 World champion in Kuramagomed Kuramagomedov of Russia
