The second standard student of the NSS Hill Spring International School reigned supreme in all the three categories - rapid, blitz and standard -- and achieved the feat of being the only Indian to bag all the crowns in the competition, said a media release here today.
He overcame the challenges from 158 participants from 20 countries across the world, the release said.
Kush won the rapid format with a fine score of 6.5 points out of a possible 7.
In the standard format, the trainee of the Mumbai Chess Academy (SMCA) registered seven wins and a couple of draws to assert his position atop the table.

Kush had to overcome a few obstacles to remain unbeaten in the championship. His game against T D Wickramarathne lasted for more than three hours which he eventually clinched with a queen side attack to show the Sri Lankan champion the exit door.
"Kush has the potential to rewrite history books and this is just a beginning. He will achieve many more in the days to come", the coach added.
