Anastasia Smirnova has become Russia's first dual moguls world champion following her landmark triumph in Almaty.
The 18-year-old beat compatriot Viktoria Lazarenko in the final to earn her first World Championship gold and follow up the moguls bronze she won on Monday.
Smirnova saved her best until last with 83.08 points in the gold medal run, just over seven clear of Lazarenko - who won her semi-final with 84.51 points but couldn't scale the same heights in the showpiece.
