Lev Aronian joined the leaders at the Alekhine Memorial thanks to a victory against Peter Svidler in round four.
Svidler played his favourite Gruenfeld defence, and an interesting battle ensued until Svidler slipped up with 32...Rf7 and the game came to an abrupt end just 4 moves later.
The Armenian's win made some amends for his very costly 11th round loss to Svidler at the recent
Candidates Tournament in London.
All the other games were drawn in round four, but not without plenty of fight, especially the 72-move struggle between Laurent Fressinet and Michael Adams.
Our on-site reporter, Jason Stoneking spoke with the players after the round...
