{5th round of the Shamkir Chess 2014, Vugar Gashimov's memorial. We were in
different tournament situations, I was on 50 percent, Magnus was at +1 after
he lost to Caruana before this game with Black. Certainly an interesting fight
was ahead! It's always interesting to play against the World Champion and I
have enjoyed this fight.} 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 {King's
Indian Defence. No comments.} 5. Nge2 O-O 6. Ng3 {There are so many moves and

all the possible plans in Bologan-Mamedov, 2014 Euro Cup Rhodes, ended in a
draw.}) 7. d5 a5 8. Be2 Na6 9. h4 {It's not as agressive as it looks, only if
Black allows h5 it becomes a kind of tactical and offensive approach, in

faster.} h5 (9... c6 10. h5 cxd5 11. cxd5 Nc5 12. Be3 Qb6 {It was played in
Lutz-Gelfand, Horgen 1994. Gelfand won this game. Lutz never castled and tried
a Nf1-d2 plan, which is going nowhere as after Nc4 Black may just go back to
c7 threatening ...b5 later on. The Computer suggests to change directions here
and go for 0-0 h6-Qd2 and playing on the queenside. Claims White is better but

the game, are better with the a3-pawn creating new threats to White's king.})
