As Berg received his chess education in the shadow of national legend Ulf Andersson, it might be expected that his playing style would mirror that of Sweden's most successful player of the modern era.

However, the styles of the players are almost polar opposites, the younger man showing a distinct preference for aggressive, dynamic chess.

He earned his GM title in 2004, following a number of tournament successes, including wins at Budapest 1999, Skellefteå 2001 (shared with Jonny Hector) and Bermuda 2002 (after a play-off).

There have been other notable results in international competition; he was joint winner of Stockholm's Rilton Cup in 2004/5 (with Sergei Volkov and Evgeny Gleizerov), won outright at Sóller in 2006 and was fourth behind Ivanchuk, Karpov and Kasimdzhanov at the Keres Memorial the same year.

[1] Berg is regularly selected to represent his country at major team events and following a significant upswing in his rating, nowadays plays on board one.
