Of course. White can never capture this or push past, as his remaining pawn structure (not to mention the c5-square) would become hopelessly weak; so he is consigned to waiting for Black to find the best moment to open the a-file.

What could be more natural than to bring the queen to the g-file where Black's king resides? In principle, White does not have much advantage, but Black now needs to be careful, and the cost of further inaccuracies is high.

Rd 4 at Alitbox Norway - Aronian beat Mamedyarov & Karjakin beat Vachier-Lagrave. All other games drawn. Caruana did not play Ding Liren as Ding is in the hospital with a broken hip after a bicycle accident. He may drop out. If so, his 3 draws will be removed from the event.
Round five pairings (Saturday): Carlsen-Anand, Caruana-Karjakin, Mamedyarov-Nakamura, MVL-Aronian, So-Ding.
