Jobava tries to get out of well known theoretical paths as quickly as possible.
The idea behind this queen sally seems to me to be a prophylatic one. Black
wants to interfere with White's normal setup of Bd3, Qc2 and Ne2, which would
not now be possible as the pawn on g2 would be en prise. Jobava had a terrible
result at Wijk Aan Zee, but good, bad or indifferent his games are always
watchable. He is known as an entertainer in chess, but I wonder if he is
trying to play up to this reputation a little bit too much and his results are
suffering as a result. The problem is: when you play the very best players in
the world, if you avoid the main-lines then you are often just playing dubious
openings.} (6... Bd6 {is much more normal. The main attraction of this opening
is that Black's position is very solid and easy to play. He puts the rook on
the e-file, the knight on d7 and the queen on c7. You can play all these moves

this case it was unwarranted. Especially as from White's point of view this

{In the third round of the FIDE Grand Swiss at Isle of Man I faced rising star
Jeffery Xiong from the U.S.} 1. e4 c6 2. d4 d5 3. Nd2 dxe4 4. Nxe4 Nf6 {
This line has gained popularity in recent years as it has been employed by
numerous top players, including Magnus Carlsen. The popularity lies in the
fact that Black obtains a solid position, yet can play for a win if White is
too ambitious. With a lot of pieces remaining on the board, the positions can
become quite complex.} 5. Nxf6+ exf6 6. c3 Bd6 7. Bd3 O-O 8. Qc2 Re8+ 9. Ne2 h5
$5 {This is the move that rekindled the 4...Nf6 variation. Black expands on
the kingside and can connect this advance with sacrifice ideas if White
castles short. If White chooses to put his king on the queen side, it is often
difficult to open files against the black king. The pawn formation with the
doubled f-pawns proves to be difficult to crack. The h-pawn advance also has
its drawbacks. Obviously, the black king is a bit more airy. Furthermore, the
h-pawn can become a target and sometimes even fall.} 10. O-O h4 11. h3 {
The h-pawn should not be allowed to advance even further since then the white
king would really start feeling uncomfortable.} Nd7 12. Be3 Nf8 13. Rad1 {
I had expected this line and prepared it in some detail before the game. Black
has different setups to organize his pieces. White in the meantime will try to
get his queenside majority going while constantly being alert for threats
against the king, especially on the b8-h2 diagonal.} Bd7 $5 {Not the main move,
but quite logical. Jeffery keeps the e-file open for the rook which allows for
tactical ideas in some cases.} (13... Bc7 {Black prepares the battery on the
b8-h2 diagonal; this has been seen the most often.} 14. c4 Qd6 15. Nf4 Bb8 16.
Rfe1 {was comfortable for White just a few days later in Vocaturo,D (2620)
-Howell,D (2694) Douglas 2019. It shows the complexity of this variation that
White went astray in a winning position and Black came up on top in the end.})
14. Rfe1 Qc8 {Black is not subtle about his intentions. He wants to sacrifice
on h3 and mate me. Exactly those ideas make this line quite appealing for the
second player.} 15. Nf4 {I had mixed feelings about this move. On the on hand,
I stopped the threat of Bxh3 and sometimes can even initiate attacking ideas
myself with Nf4-h5. On the other hand, the knight feels somewhat loose on f4
and I have to be wary of tactical ideas.} (15. c4 $4 {Ignoring the threat
would not end well for White:} Bxh3 16. gxh3 Qxh3 $19) (15. Bf4 $4 {Here we
see the advantage of placing the bishop on d7 instead of e6, keeping the
e-file open for the rook.} Rxe2 $1 16. Rxe2 Bxf4 $19) 15... Ne6 $6 {A step in
the wrong direction. It seems Jeffery had already his ill-advised plan in mind
which we will see in the game.} (15... Qc7 {was the move I clearly expected.}
16. Nh5 Qa5 {Activating the queen and once again hitting the knight.} 17. Qe2 {
was my intention to bring the queen closer to the black king via f3.} (17. d5 {
is a nice idea, but can be diffused by} Re5 $1 (17... cxd5 18. Bh6 $1 {is one
cute motif in the position.}) 18. dxc6 Bxc6 19. Nf4 Rd8 $11 {This seems
completely fine for Black.}) 17... Qxa2 18. c4 Qb3 $13 {This is the position I
wanted to play which seemed to offer good practical chances. Subsequent
analysis revealed that it is indeed equal, usually ending in a perpetual of
some sort.}) 16. Nh5 $5 {Keeping the knights on the board and therefore
increasing the tension. With the knight on h5, different tactical ideas like
sacrifices on f6 or g7 as well as moves like Be3-h6 are in the air. However,
the simple 16.Nxe6 would have promised me a long-term advantage.} (16. Nxe6
Bxe6 17. Bh7+ Kh8 18. Be4 $14 {This is more or less what White hopes to
achieve in this variation. The counterplay against the king is reduced and
sooner or later, White can create a passed pawn.}) 16... Ng5 $2 {After my move,
I immediately got up to take a bathroom break. I was quite surprised to return
and already see this move appear on the board. I had thought this move to be
impossible and indeed, it should lead to a losing position.} (16... Qc7 {
Once again improving the queen and connecting the rooks was better.} 17. Bf5
