Isle of Man (UK) | R Vaishali crashed through the defences of former world women's champion Mariya Muzychuk of Ukraine to jump to joint lead on 3.5 points after the end of the fourth round of FIDE women's Grand Swiss, a part of the World Championship cycle, here.

With seven rounds still to come in the strongest Swiss for women, Vaishali shares the lead with Tan Zhongyi of China, Anna Muzychuk of Ukraine and Assaubayeva Bibisara of Kazakhstan.

After making her third and final Grandmaster norm at the just concluded Qatar Masters, it was clear that Vaishali is ready for the bigger challenges. As it turned out in the match-up against one of the world's best, the Chennai-based player delivered her best with yet another scintillating performance thanks to her brilliant attacking skills.
