Later on in the tournament, in his games against Vallejo and Aronian, Gashimov

move.} ({The main alternative is} 9... Qc7 {In the comments to Brynell,S (2496)

whole variation based on the early check on a4.}) 10. Bxd6 Qb6 11. Be5 O-O 12.
e3 {I remember that when I was young I got fascinated by this position,
considering it to be rather hermetic for mere mortals and admiring those who
would play it and live to tell about it. Despite the progress of engines, I
still consider this to be valid. When trying to check the traditional point of
view, I was very surprised to see that none of my good old Russian Benoni
books (Kapengut and Stojiar/Kondratjev) mention it!} b4 {A relatively rare
move. Black wins space with gain of time, but weakens the c4-square. If White
had the time to play Nd2-c4, he would get a crushing strategic advantage.} ({

weakness of the b5-square will remain. The course of the game makes me wonder
whether it was an over the board inspiration or faulty remembering of old
analysis.} ({I do not like} 13... Bf5 {either. This simply looks like a loss

{I look forward to getting invited to Wijk aan Zee again next year. This
important tournament has had such a long and prestigious tradition that being
in a small and windy town for almost 20 days is totally worth it. Going into
the last round on the back of a loss against Anish Giri was tough, but at the
same time losses are inevitable. I told myself never to give up and just to
play my own game. Loek was also having a relatively unstable tournament, and
anything can happen for the last round.} 1. d4 Nf6 2. c4 e6 3. Nf3 c5 {A
