Copenhagen: Indian shuttlers Akshay Dewalkar and Pranaav Jerry Chopra came out on top in a topsy-turvy opening match to proceed to the men's doubles second round of the World Championships being held at the 9,200-seater Ballerup Super Arena here Monday.

However, it was the end of the road for Tarun Kona and Ashwini Ponnappa whose campaign in the mixed doubles category came to a crashing end on the first day of the sport's most prestigious tournament.
