Best rating:
...d
Of course all this has been played many times before.
It was clearly not the tournament of Caruana or So, as both
players missed a lot of chances in the previous games and
were ranked on the lower end of the crosstable. Anyhow, the
game we are going to see is a very exciting one. From the
opening Caruana managed to get a big attack on So’s king and
a huge advantage, but he missed the best continuation in the
tactical calculations. The game then became very unclear and
finally ended up in a draw.
.Nf
Nf
.c
To guess Caruana’s openings is a di icult task.
Fabiano is very well-prepared and plays both .e and .d .
...b
.g c
In the current position there are a lot
of di erent move orders and many di erent positions
depending on who wants to reach what...
.Bg
The system with g and Bg is one of the most popular
ones.
...Bb
.O-O g
[ ...e is the other main possibility.]
.d cxd .Qxd
The line with Qxd is a very tricky one.
White’s idea is simple, to get the queen to h in a good
moment and to play Bh followed by Ng , with attack.
...Bg
.Nc
.Bh !
An excellent move with multiple ideas. First of all
White is not afraid of Bxf exf which would just lead to a

Now that Black doesn’t have any more
useful moves, So castles.
...O-O .Qh
and of course Caruana is going for the main
idea of the whole line.
...Re
Very logical. In case White could exchange the dark
squared bishops, White’s position should be a bit better, so

better position for White. Now he can move the knight from
f without exchanging the white squared bishops, which is
good, and the rook on c is also sort of pinned.
...Rc
.g
and here comes Caruana! White’s idea is
simply to play g next.
...Qa
A very logical reply, even if the queen is out of play
on a , but now Black is prepared to answer g with Ne .
.Bd
White wants to finally play g and exchange the
bishops, which would weaken the position of the black king
a lot. [In case of .g

very unclear.]
the h square. This is a veryunpleasant position in a practical
game.
...e
A er this move White gets a clear target, the d pawn,
but Black was clearly very afraid of the upcoming Nd move.
[In case of a passive move like ...Qd
.Nd
Bxd
.cxd
White’s position is clearly much better.]
.Be !
Great play by White! The d pawn is in serious
trouble.
...Qb
.Bf
Another good move by White. [A big
mistake would be .Rxd ?

Black is fine.]

This is just a blunder... [Th only way to go on was

and White gives back the present... [Of course
Caruana saw .Bxd

Here I have to disagree with So. This move just
looks too dangerous to me. [ ...b !? Maybe Black could have

maybe even here White can keep some advantage by playing

Of course there is no reason to hesitate about playing

Now Black must always be careful about

Now the position is really complex.

The threats around the black king are still not
gone, but a little less dangerous.
