I have found the video of Marti's victory:
Giulia Quintavalle was the gold medal winner of 2008 Beijing Olimpic.
Chess mate in five mooves for the blue:
1) Marti force Giulia in an unconfortable double sleeve grip
2) Marti pull Giula down and foreward with both arms
3) Marti stoped pulling and Giulia reacted raising and shifting her weight backward.
4) Marti enhanced Glilia's reaction to put her out of balance
5) Marti entered in a fantastic double sleeve grip left kouchi gari
