Gibraltar: Five-time world champion Viswanathan Anand continued to struggle with his form, as he lost to 16-year old IM Benjamin Gledura of Hungary in the seventh round of the Masters section of Gibraltar International Chess festival, here on Tuesday.

With just three rounds to come in the £185,000 festival, Anand remained on four points from his seven games and went out of contention for a podium finish.

For the record, Anand played the Slav defence and, on another day, against his elite peers would have drawn the resulting endgame fairly easily.

However, one mistake led to another and what looked like a certain draw on move 15 turned in to a lost endgame. Gledura was spot on, when he had to find the best moves in the endgame once Anand erred decisively.

David Anton Guijjaro, the 20-year old Spanish GM emerged as the sole leader on six points, defeating Richard Rapport of Hungary. Guijarro is now followed by as many as 15-players on 5.5 points apiece, after a draw-filled day at the top of the table.

Four Indians, P Harikrishna, Abhijeet Gupta, Vidit Gujrathi and S P Sethuraman, are sharing the second spot on 5.5 points apiece, along with Maxime Vachier-Lagrave of France, Radoslav Wojtaszek of Poland, Ni Hua of China and eight others.
