Playing black, Gujrathi scored his fourth victory of the tournament when Arnaudov could not keep track of his pawns and from a pawn plus position which was a likely draw, walked in to a hopeless endgame after losing two pawns.
The victory made Gujrathi the best performing Indian so far in the tournament as the Nasik boy took his tally to an enviable 4.5 points. The lead is shared by Zbynyk Hracek of Czech Republic and Vladislav Nevednichy of Romania who both have five points apiece from five rounds.
Abhijeet Gupta rose back in the tournament at the expense of Zurab Javakhadze of Georgia after his king got stuck in the center early in the opening. However, the Indian made good use of his pair of Bishops to keep the attack in check and won with some deft manoeuvring.
Sahaj Grover was surprised by the draw offer coming from higher rated Bulgarian Grandmaster Rusev Krasimir wherein the latter had an extra pawn after the trade of queens. As it transpired, Krasimir had missed a knight sortie that would have kept the game alive and thought Grover was excellently placed.
