In the process of becoming the Bulgarian Champion of 1984 (shared), 1986 and 1989, he rapidly became recognised as Bulgaria's number one player, taking over from Ivan Radulov and eventually giving way to Veselin Topalov.

He was a winner at Sarajevo 1986 (and would meet board boy Ivan Sokolov there again, some 15 years later), San Bernardino 1988, Elenite (Burgas) 1992 (ahead of Sokolov, Topalov, Josif Dorfman, Yuri Razuvayev and Vassilios Kotronias) and the 1993 Budapest Zonal (ahead of Judit Polgár and Ľubomír Ftáčnik).

First at Sarajevo 2001 (his first Category 16 tournament win - ahead of Topalov, Ilya Smirin, Alexei Dreev and Ivan Sokolov) and first at Bad Wörishofen 2002.

This was also the year that he won a bronze medal at the European Individual Chess Championship (behind Zdenko Kožul and Vassily Ivanchuk).

Accordingly, these results have caused his Elo rating to advance rapidly during 2005 and 2006, reaching 2680 in July 2006, and placing him at number 26 in the (FIDE) World's 100 top players.

In December 2009, he tied for 1st-4th with Georg Meier, Julio Granda and Viktor Láznička in the 19th Magistral Pamplona Tournament.
