Vakhtangi Chidrashvili secured Georgia's first gold of the International Sambo Federation World Sambo Championships as Russia won another seven titles here.
The Georgian, in impeccable form throughout the preliminary rounds, earned a narrow victory over Russian Sayan Khertek in the final of the 57 kilograms division.
Avazbek Abdujalilov of Uzbekistan and Mongolia's Maral-erdene Chimeddorj claimed bronze medals.
Russia continued to dominate on a day when top seeds tumbled out of the Championships at Sukwoo Culture Gym,
They reached eight of nine finals and only Khertek's silver blemished their dominance of the second day of competition.
The women's 80kg contest provided the fireworks from the outset as defending champion Sviatlana Tsimashenka of Belarus was defeated by eventual bronze medallist Halyna Kovalska from Ukraine.
Top seed Deborah Masy from Belgium was packing her bags in the second round, leaving the door open for Bulgarian Mariya Oryashkova to take gold.
She defeated Rui Takahashi from Japan in the only final not to feature a Russian sambist today.
There were more shocks as Armenian Grigor Mkhitaryan, top seed in the men's 57kg category, lost to Kaiyrberdi Aidynbay from Kazakhstan, while Brazil's 100kg top seed Cassio Lisboa was quickly despatched by Australian Addison Carlyon.
