h4 {Morozevich has beenplaying this line a lot and then it has recently been
played by Nepo and Hikaru. I had a look from White's side and 8...Qe6 bothered
me - it was played by Grischuk and Kramnik as Black in 2018} Qe6 9. g3 Nb4 $5 {
[%cal Gc8a6] A novelty and a strong one. Tomczak sank into deep thought
immediately after this move.} (9... d6 {Earlier both Grischuk and Kramnik
opted for this.}) 10. c4 Ba6 11. Bf4 (11. a3 Bxc4 $1 {is the tactical
justification} 12. Qxc4 Qxc4 13. Bxc4 Nc2+ 14. Ke2 Nxa1 {It turns out that it
won't be easy to trap the knight on a1.} 15. Nc3 (15. b4 a5) 15... Rb8 16. b4
a5) (11. b3 {would have been a better choice.}) 11... d5 $1 {As early as move
11 Kramnik has managed to get a clear advantage. At this stage it looked like
it would be a repetition of how he crushed Beradse in round 3.} 12. a3 (12.

Qg6 and Qf5 here} (13... Qg6 {[%cal Gg6e4]} 14. Bxc4 dxc4 (14... Qe4+ 15. Be2)

be to play Nd3.} Nd3 (15... Nc2 {The engine prefers this}) 16. Qf3 Qe6 $5 $17 {
[%cal Ge6d5] In order not to calculate any complex line} (16... Bc5 {This is
stronger!} 17. Nd2 O-O-O $1 18. Nxc4 Nxf4 19. Qxf4 Rd4 20. Qc1 Rxh4 $19)) (

anymore} 15. Nc3 (15. Nd2 $142 $132) 15... Nc5 $1 16. b4 d4 $1 {Once again

keep the advantage and it is also a typical Kramnik kind of move.} 19. Qxd5

There is nothing wrong with Black's position. In fact, it’s still slightly
better.} 25. Bg5 Qa2 $6 {Based on an oversight. Clearly Kramnik wanted to keep
his rook on the d-file and also wanted to stop any Qc2-Qf5 idea hence Qa2 made
sense. It gains a tempo and also allows black to keep the rook on the d-file.
Unfortunately, all of a sudden the attack doesn't come on h7 but the f8-square
becomes vulnerable!} (25... Bd4 $1 {Not a very obvious move. Why would Black
force White to move the queen when anyway White wants to move it eventually?
The point is that the white queen is right now protecting the g3-square and
hence it had to be moved! This feels absurd! Why on earth does g3 have to be
protected? With engines on it is very easy to say how come Kramnik didn't see
this two-move tactic but that is not the way human brain functions. Somehow
this move Bd4 looks like an idiotic move just helping White to get onto a
better square unless the forthcoming tactic is spotted.} 26. Qc2 Rg6 $1 $17 {
[%csl Rg3] The point! Now suddenly it appears that Black need not save the
d8-rook after all! g3 is hanging!}) 26. Rh2 {So now Black can keep the rook on
the d-file. White also cannot approach the h7-pawn easily. The important
question is which square to choose?} Rd5 $4 (26... Rd4 {still worse but not
lost yet} 27. Qf3 Qd5 28. Qh5 Qe4 29. Bf6 $36) 27. Qb4 {[%cal Gb4f8,Gb4h4] The
threat on the f8-square came out of nowhere. It was not even a threat all this
while.} c5 (27... Kxg7 28. Qh4 $18) 28. Qh4 {Now it's all over.} h6 29. Bxh6
