So the statistics of round 4 make unusual reading: White wins 0, draws 13, Black wins 3!
Yesterday, Mamedyarov against Laznicka, and Svidler against Shirov, virtually assured their qualification and (after drawing) they will be joined in round 5 by Karjakin who outplayed Vitiugov in today's round. He was successful with a fairly recent idea in the Nimzoindian against which White hasn't been able to show anything convincing.
The other five matches have featured only draws, but Ponomariov seems to have missed a win deep into the knight endgame against Bacrot. He will be kicking himself letting the advantage slip, but a few moves earlier Bacrot had a 'book' draw but erred, so neither player will be fully satisfied with their technique!
Caruana also maintained an enduring advantage against Gashimov but couldn't convert.
