{This game occurred in the 7th round of the Asian Continental Championships.

prepared and ready to play objectively.} 1. c4 e6 2. g3 d5 3. Bg2 Nf6 4. Nf3

especially after Wesley's nice win over Wojtaszek in the Tata Steel
Supertournament.} Nbd7 {This move order doesn't really matter to me as I
usually go for Closed System setups, as opposed to Open lines starting with
dxc4.} ({The aforementioned game went:} 6... c5 7. O-O Nc6 8. dxc5 d4 9. a3 a5

Black in the previous round:} Ba6 13. Nf1 Rc8 14. Qd1 Nb8 $1 {[%csl Rc2,Rd3,

8... Ne4 $1 {I think it's ideal and best to prevent White from gaining more
central space by forming the Stonewall structure. Being also familiar with
Botvinnik's games and Carlsen's numerous wins with the Dutch Stonewall also
gave me confidence to play it!} 9. Bb2 f5 10. Nbd2 a5 {This rook pawn thrust
is another typical idea I'm familiar with, and I recalled that Carlsen used
this plan to win against Anand in one Grenke super tournament.} 11. Ne1 {
White plans place his knights on d3 and f3 and eventually push back my
e4-knight, or he could push me back quickly and go for the e2-e4 break! This
means that something has to be done quickly.} ({If} 11. Nxe4 {I was intending}

idea by creating a future home for one of my knights on c4.} 12. Ndf3 (12. cxb5
