{One of the starting rounds and my second game with White in the tournament.
Probably after the first game against Caruana, that ended in a draw, I was
eager to try for more in this one :)  Eine der Startrunden und meine zweite
Partie mit Weiß in dem Turnier. Nach der ersten Partie gegen Caruana, die mit
Remis endete, war ich in dieser wohl begierig, nach mehr zu streben :)} 1. d4
Nf6 2. c4 g6 3. Nf3 Bg7 4. g3 d5 {One of the main replies in the g3 system's
theory, Black challenges White in the centre and is going to recapture on d5
with a piece after c4xd5.  Ein der Haupterwiderungen in der Theorie des
g3-Systems. Schwarz fordert Weiß im Zentrum heraus und wird nach c4xd5 auf d5
mit einer Figur wiedernehmen.} 5. Bg2 {The pawn on c4 is hanging, is it a
Queen's Gambit with bishops on the g-file? Is it a Catalan with Black's bishop
on g7? Let's call it a pawn sacrifice in the Grünfeld on move 5. Der Bauer auf
c4 hängt, ist es ein Damengambit mit den Läufern auf der g-Linie? Ist es ein
Katalane mit dem schwarzen Läufer auf g7? Nennen wir es ein Bauernopfer im
Grünfeld im 5. Zug.} dxc4 {Accepted...  Angenommen...} 6. Na3 {And now we are
back on earth, of course White is not going to let Black play with a pawn up
in such an early stage. Und nun sind wir wieder zurück auf der Erde, natürlich
wird Weiß in so einer frühen Phase Schwarz nicht erlauben, mit einem Bauern
mehr zu spielen.} Nc6 {Black has many alternatives of course. He can play ...
c7-c5 instead, or ...0-0 or ...c3. But David prefers this move and now we are
in a less explored theoretical line. Schwarz hat natürlich viele Alternativen.
Er kann stattdessen ...c7-c5 spielen oder ...0-0 bzw. ...c3. Aber David
bevorzugt diesen Zug, und jetzt befinden wir uns in einem weniger erforschten
theoretischen Abspiel.} 7. Nxc4 Be6 8. b3 {Took a pawn, defending the knight,
all by the rules. Einen Bauern genommen, den Springer gedeckt, alles nach den
Regeln.} a5 {Black is going to attack the a2-b3 chain, but he has to watch out
for Ng5!?, as after my next move it becomes a real threat! Schwarz will die
a2-b3-Kette angreifen, muss aber auf Sg5!? achten, denn nach meinem nächsten
Zug wird dies eine reale Drohung!} 9. Bb2 Bd5 {Schwarz verhindert also Ng5 und
wird als nächstes a4 spielen!} (9... a4 10. Ng5 $5 $36 (10. Nfe5 $14)) 10. Rc1

aber ich wollte ...a4 verhindern. Was vielleicht gar keine Drohung ist :)})

Black of the chance of pushing his c-pawn and generally piece placement is not
that obvious. Jetzt ist es problematisch, die Figuren zu platzieren; der
Springer auf c6 nimmt Schwarz die Möglichkeit, seinen c-Bauern vorzustoßen,
und generell ist die Figurenaufstellung nicht so offensichtlich.} (11... a4 12.

very bad, but I was surprised that it's not winning outright. 2 bishops and a
strong center, also the c7-pawn is hanging in the event of Rxc4. Schwarz muss
so spielen. Das Endspiel steht sehr schlecht, aber ich war überrascht, dass es
nicht sofort gewonnen ist. Zwei Läufer und ein starkes Zentrum, außerdem hängt
nach Rxc4 der Bauer c7.} 16. Rxc4 (16. bxc4 $1 {I think this move is easier.

Ungenauigkeit.} Rfd8 $14 {White is certainly better, but Black has good
compensation too; ...Bf8 is coming, and also a5-a4 followed by Ne3.
Furthermore it's not obvious how to stabilise the piece in order to convert
the plus pawn advantage into the full point. Weiß steht sicherlich besser,
aber auch Schwarz hat gute Kompensation; ...Bf8 kommt, und auch a5-a4 nebst
Ne3. Außerdem ist nicht leicht zu stehen, wie die Figuren zu stabilisieren
sind, um den Mehrbauernvorteil in den vollen Punkt zu verwandeln.}) 19... Ngxe5
20. Bc3 $1 $18 {and this looks technically winning for White! The knight comes
to d5, where it supports the centre, and there follows f4. und dies sieht aus
wie ein technischer Gewinn für Weiß! Der Springer kommt nach d5, wo er das
Zentrum stützt, und es folgt f4.}) 16... e6 $1 {Yes, White is still better but
I am not sure at all what is the best way here. Probably it's about a e5-Ne4

The computer likes my Rxc4 and suggests it as the first line, because he
thinks this position is winning. But there is the real compensation that Black
has due to the open files and weakened 2nd rank in White's camp.  Der Computer
mag mein Rxc4 und schlägt es als erste Variante vor, weil er meint, dass diese
Stellung gewonnen ist. Es gibt aber reale Kompensation, die Schwarz hat,
aufgrund der offenen Linien und der geschwächten 2. Reihe im weißen Lager.} 25.

missed by David certainly. Now White is a bishop up in a winning position. So
