   Aug-31-15 Nakamura vs Aronian, 2015
 
Ulhumbrus: Nakamura may have hoped that after a5 either Black's a6 pawn would become a target instead of his a5 pawn or else as in the game Carlsen vs Aronian, 2013 Black's a6 pawn would become a target on the a file after White's a5 pawn fell. It was not to be: Aronian refrained from taking
 
   Aug-31-15 Caruana vs M Vachier-Lagrave, 2015
 
Ulhumbrus: One justification for 9 Bb3 instead of 9 Bc2 is that on c2 the bishop becomes a potential target for the black queen on c7 and the potential threat of ..cxd4 hinders the development of White's queen's knight as that development obstructs White's queen's defence of the white king's
 
   Aug-31-15 Topalov vs A Giri, 2015
 
Ulhumbrus: 13 Bxe6 helps Black's king to develop by 13...Kxe6. If we assume that White may and will play f2-f4, this suggests 13 Rhf1 followed by f2-f4
 
   Aug-31-15 Anand vs W So, 2015
 
Ulhumbrus: With 12...b5!! So shows his strength. The pawn on b5 is a dynamic weakness but a static strength and So will dislocate his queen side pawns by ...ba only when he considers the moment to be right. Anand said that he was able to draw after Black accpted the queen. GM Seirawan ...
 
   Aug-31-15 Carlsen vs Grischuk, 2015 (replies)
 
Ulhumbrus: If 18 ba allows Black to blockade White's c pawn on c5 an alternative is 18 a3 followed by Nb3 Comments by Alejandro Ramirez on the chess base (here is a link: http://en.chessbase.com/post/sinque... )suggest that with 32 g4? Carlsen begins - to use Tarrasch's expression - to ...
 
   Aug-30-15 Aronian vs Carlsen, 2015 (replies)
 
Ulhumbrus: The computer evaluations suggested that 18 Bxd4 was better than 18 Nxd4. If so, can one suggest a justification for 18 Bxd4 in place of 18 Nxd4? One justification is that after 18 Nxd4 exd4 the d4 pawn obstructs White's bishop whereas it won't obstruct White's king's knight. In ...
 
   Aug-30-15 M Vachier-Lagrave vs Topalov, 2015 (replies)
 
Ulhumbrus: 18 e6 opens lines in a position where White is ahead in development. One of the commentators - it may have been GM Ashley - compared this thrust to the thrust 16 e6 in the game Kasparov vs Kramnik, 2001 GM Ashley indicated ( amongst other things) that 18...Bxe6 presented a target ...
 
   Aug-30-15 W So vs Nakamura, 2015 (replies)
 
Ulhumbrus: On 29...h3+ 30 Kxh3 the sacrifices 30...Rf2!! (and following 31 Bxf2) 31...Qxf2!! serve to displace White's knight on d3 from its cover of the square f4 so that (after 32 Nxf2) the check 32...Nf4+ becomes possible, leading to mate (after 33 Kh4 Bg5)
 
   Aug-29-15 A Giri vs Anand, 2015
 
Ulhumbrus: One justification for 10...e5 is that White has exposed his king side
 
   Aug-29-15 Grischuk vs Caruana, 2015 (replies)
 
Ulhumbrus: 15...Nc5 offers a piece sacrifice. The GM comments suggested that in one line Black might win if White were to try to keep the piece but that White might be able to turn the tables by offering to return the piece. The result of a game like this may depend on which of the players ...
