Joint leader P Karthikeyan moved into sole lead with 7.5 points as second seed Grandmaster Ahmed Adly of Egypt, citing illness, failed to turn up for the eighth round at the Apollo Engineering College Commonwealth Chess Championships 2012 at SDAT Multipurpose Indoor Stadium, Chennai here today.
Following Karthikeyan at 7.0 points were Grandmasters Sergei Tiviakov (The Netherlands) and M R Venkatesh (India).
In the top board, Tiviakov faced the advanced French defence from Rathnakaran, and started pressing for the initiative from the word go. Tiviakov further made in-roads as the Indian failed to see the intervening bishop check on the 19th move losing a pawn.
Moving the black king out of its shelter, Tiviakov went all out to corner the black king and forced the game in his favor after 33 moves.
Chennai based Ram S Krishnan made his third and final International Master Norm scoring over two time National Premier Champion Tania Sachdev. Logging in 6.5 points Ram completed the requirement for a nine game International Master Norm.
The Nimzo Indian game saw Tania going along the theoretical lines, before she threw in a knight sacrifice on the black monarch. Ram kept the material, defended accurately and clinched the crucial win after 31 moves.
