good thing about Dubai open was that even the final round began at 17:30! So

the resulting position looks like it came from the Tarrasch Defence, possibly
with an extra tempo for Black thanks to White's Nf3-d4-f3.}) 7... O-O 8. Nf3 {
Normally White wouldn't retreat with that knight,} ({but} 8. Be2 d5 {is known
to be equal.}) 8... Qa5 $5 {Still a relatively fresh idea. Black insists on
his central break.} ({A Hedgehog-like formation can be reached via the standard
} 8... Qc7 9. Be2 b6 10. O-O Bb7 {Anand had this position with Black against
Vallejo back in 2005!}) 9. Bd2 {I'm rather surprised with this one.} ({One

pawns after} 13. Nd4 Qe5 14. Nxc6 bxc6 {as his pawn formation provides support
to his Nd5, as seen in Huzman-Timofeev, 2016 and Inarkiev-Gelfand 2017}) 13...

We talked about the c6-pawn in the note above, but here things take a bit of a
different shape after} 13... Rd8 14. Nd4 Qg6 15. Nxd5 Rxd5 16. Nxc6 bxc6 17.
Bf3 {as White got himself a free ride in Wojtaszek-Borisek, 2015. Naturally,
Carlsen wouldn't mind a repeat of such a scenario, but this being a Wojtaszek
game made it very unlikely to escape a careful examination in Anand's lab.})
14. Nd4 Qc5 15. Nxc6 Qxc6 16. Bf3 {White's only hope in this dry desert type
of position is the pressure against b7, but Black's next takes care of that.}
