New Delhi: Unheralded Arjun Kalyan shocked Grandmaster Neelotpal Das in the first round of the Commonwealth Chess Championship that started here at the Park Plaza hotel here.

In another upset of the day, Woman Grandmaster Tania Sachdev also went down to Anzel Solomons of South Africa when the Indian was declared lost on time.

The championship got off to a flier for the higher ranked players as almost all of them scored easily over lesser known opponents in the first round of this nine-rounds championship.

Top seed and rating favourite Abhijeet Gupta scored over T Selvabharathy from the white side of a Queen pawn game. The highest ranked player finished the game in quick time.

Playing after a long time in India, Grandmaster Koneru Humpy also had little difficulties in tackling Soham Datar who played white. Humpy, seeded second here, is by far the hot favourite for the women’s crown and at the same time give the other Grandmasters here a run for their money.

Local stars Vaibhav Suri and Sahaj Grover also had a field day with success but the later had to sweat a little harder before he could beat Abhinav Gola.
