Grandmaster R Praggnanandhaa blundered for the second day running and lost to Richard Rapport of Romania in the third round of the Prague Masters Chess tournament underway in Prague. After briefly going ahead of Viswanthan Anand and attaining the top Indian status in the live rating list, this double blow cost the Indian dearly, and now a lot of hard-work remains in the last six rounds of the 10-player round-robin contest. It was drama all over, as Praggnanandhaa was not the only one to blow away his chances. Nodirbek Abdusattarov of Uzbekistan turned the tables on local star David Navara from a nearly hopeless position when the latter failed to keep his nerves under pressure after attaining a winning position.
