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
Re7 (17... Ng5 {was a line I calculated.} 18. f4 Bxf5 19. Qxf5 Ne4 20. Bf2 $1 {
This is quite an important move, getting rid of the knight on e4.} Nxf2 21.
Kxf2 Bf8 22. Qg4 Qd6 23. Qxh4 $14 {Here we see an example of the h-pawn
getting picked up.}) 18. Bd2 Ng5 (18... Rae8 19. Re4 $1 $18 {Again collecting
the h-pawn and also including the rook in the attack.}) 19. Rxe7 Bxe7 20. Bd3
$14 {Black has stopped White from winning the h-pawn for now. As the threats
against the white king are also less prominent, White still has the
strategical edge and also the idea f2-f4 to count on. Therefore, White is a
bit better.}) 17. f4 Nxh3+ (17... Bxh3 {is easily refuted by} 18. fxg5 Bg4 19.
Nxg7 $1 Bxd1 20. Qxd1 Kxg7 21. gxf6+ {The attack is unstoppable, for example}
Kxf6 22. Qf3+ Kg7 23. Bh6+ $1 {and mate will follow soon.}) 18. gxh3 Bxh3 {
The critical moment in the game. I was pondering about Qf2 or Qh2 and in the
end concluded that there is no difference between them. Boy was I wrong! One
move wins while the other draws. To my pity, I chose the wrong one.} 19. Qf2 $2
(19. Qh2 $1 {Indeed, after this move Black is lost in all variations.} Bg4 {
This is the move I also expected after 19.Qf2, therefore thinking there is no
difference.} (19... Qg4+ 20. Kf2 Qxh5 21. Qxh3 $18 {is simply an extra piece
for White.}) (19... Rxe3 20. Rxe3 Qg4+ 21. Kf2 Qxh5 (21... Qxd1 22. Be2 $1 Qd2
23. Qxh3 $18) 22. Rxh3 Qxd1 23. Rxh4 {For the moment, material is equal. But
the threat of Rh4-h8 means White will at least win a rook.} Kf8 24. Be2 $1 {
The last important precise move.} Qd2 25. Rh8+ Ke7 26. Rxa8 $18 {There is no
counterplay and White wins.}) 20. Qxh4 Bxd1 21. Nxf6+ gxf6 22. Qh7+ Kf8 23. Bf5

for a draw.} Ke7 24. Bf4+ Kd7 25. Qxf7+ Re7 26. Rxe7+ Bxe7 27. Qe6+ Ke8 28.

Black can do. He is still an exchange down and should lose sooner or later.})

19.Qh2.}) 20. Kh2 Rxe3 21. Rxe3 (21. Qxe3 {is not a good idea.} Qg2#) 21...
Qxh5 {Honestly, I had missed this move altogether, only calculating 21...Qxd1.
I can consider myself quite lucky that I am not suddenly lost.} (21... Qxd1 {
is actually also not clear because of the unfortunate placement of the knight.}

and if White can win, it will be a long road to convert.}) 22. Rxh3 (22. Rde1
Bd7 {is just terrible for White, as Black already has two pawns for the
exchange plus the weak white king.}) 22... Qxd1 23. Qxh4 {Here I suddenly
thought again that I am winning. The next black move brought me back to
reality.} Kf8 $1 {Of course Black does not give a check first, but immediately
moves his king. Now, I was panicking a bit as my time was fading and the path
to equality is not clear. However, I pulled myself together and found the
correct moves.} (23... Qd2+ 24. Kg1 Kf8 25. Qh8+ Ke7 26. Qxa8 {is simply
winning for White as there is no perpetual for Black.}) 24. Qh8+ Ke7 25. Re3+

the difference. Black can include his bishop in the attack.} 26. Kg2 Qg4+ 27.

opposite-colored bishops.}) 25... Kd7 26. Qxa8 Bxf4+ (26... Qd2+ 27. Re2 {

is also possible.} Qh4+ 29. Ke2 Qh2+ 30. Kd1 Bxe3 31. Qxb7+ Qc7 $11) 28... Bxe3

mentioning the weak white king. But the white king is not the only vulnerable
one...} 29. Qxb7+ Kd8 30. Qb8+ Kd7 (30... Qc8 31. Qd6+ Qd7 (31... Ke8 {even
loses.} 32. Be4 $18) 32. Qf8+ Kc7 33. Qxg7 {is certainly not worse for White.})

Kd7 33. Qb7+ Kd8 34. Qb8+ Kd7 35. Qb7+ {Neither side can sensibly continue,
therefore the draw by perpetual was the logical outcome. Before the game, I
had a feeling that such a wild struggle would emerge. Both Jeffery and I love
complications and a tactical mess which was fully reflected in this game.}
