{Jeffery Xiong has cemented his place as one of the top American players.
After spending three years in the 2600s, Jeffery crossed 2700 for the first
time in August of 2019. He increased his rating while eliminating Anish Giri
and Jan-Krzysztof from the World Cup en route to a quarterfinals appearance.
His ascent has forced the chess world to wonder if a "Big Five" is on the
horizon. In order to join the well-established quartet, Jeffery must be both
well-prepared and unpredictable, as he was in this game against a very solid
player who scored 11 draws at the FIDE Grand Swiss.} 1. Nf3 d5 2. d4 Nf6 3. c4
e6 4. Nc3 dxc4 {In recent games against Giri, Bluebaum, and Abasov, Jeffery
had played the direct Queen's Gambit Accepted. While he has shown a propensity
to take on c4 early, Erdos hardly could have expected his teenaged opponent to
capture it here and enter the sharp Vienna Variation. After all, in their
previous encounter just four months earlier Jeffery had played the Grunfeld.
Preparing for an elite grandmaster clearly is never easy!} 5. e4 {[#]} b5 {
Jeffery opts for a razor sharp continuation, though he stated that he didn't
check the variation specifically for this game. The main line that has been
played for decades does not provide Black the same double-edged tactical

1. c4 {I can look back at my chess career and pick out more than a few crisis
points, but only one Mount Everest. I would like to share the tale to
investigate the means I used in winning the most important game of my life. ...
After a tough, prolonged defense I suffered one of the worst hallucinations of
my career and blundered to a loss in game 23. Suddenly, Karpov was up by a
point and was only a draw away from taking back the crown he had lost to me
two years earlier. The very next day after this catastrophe, I had to take the
white pieces into a must-win game 24. Caissa, the goddess of chess, had
punished me for my conservative play, for betraying my nature. I would not be
allowed to hold on to my title without winning a game in the second half of
the match. Only once before in chess history had the champion won a final game
to retain his title. With his back against the wall, Emanuel Lasker beat Carl
Schlechter in the last game of their match in 1910. The win allowed Lasker to
draw the match and keep his title for a further eleven years. The Austrian
Schlechter had, like Karpov, a reputation as a defensive wizard. In fact, his
uncharacteristically aggressive play in the final game against Lasker has led
some historians to believe that the rules of that particular match required
him to win by two points. When preparing for my turn on the other side of this
situation, I recalled that critical encounter. What strategy should I employ
with the white pieces in this must-win final game? There was more to think
about than game 23 and game 24, of course. These were also games 119 and 120
between us, an extraordinary number of top-level encounters between the same
two players, all played in a span of thirty-nine months. It felt like one long
match, with this final game in December, 1987, the climax of what we had
started in September 1984. My plan for the final game had to consider not only
what I would like best but what my opponent would like least. And what could
be more annoying for Karpov than my turning the tables and playing like
Karpov?" -- Garry Kasparov, excerpt from "How Life Imitates Chess", 2007,

central e5 square, offering a pawn. Karpov took the bait and grabbed the pawn,
a temptation that could have led to disaster. And he had to play quickly now,
as it was still a long way to move 40, when, by the rules then in force, the
game would be adjourned and more time added before continuation the next day.
-- Kasparov, "How Life Imitates Chess"} Nxa4 32. Rxc8+ {I exchanged rooks,
leaving me with queen, knight, and bishop against his queen and two knights.
He had an extra pawn, but I had seen a tactical possibility that would give me
a powerful attack. His pieces were dangerously uncoordinated, and his king was
vulnerable. If I could penetrate into his position with my queen, I could
exploit both of these factors at the same time. The question was where to move
my queen on move 33. Karpov could only wait, knowing he would have to reply
almost immediately or he wouldn't have enough time to make the next eight
moves without losing on time. -- Kasparov, "How Life Imitates Chess"} Nxc8 33.
Qd1 {Lost in thought, I was startled by a tap on my shoulder. The Dutch
arbiter leaned over and said, "Mr. Kasparov, you have to write the moves." I
had become so wrapped up in the game that I had forgotten to make note of the
last two moves on my score sheet as required by the rules. The arbiter was of
course correct to remind me of the regulations, but what a moment to be
strict! Distracted, I played my queen to the wrong square. I missed a subtlety
and failed to see why a different move with the same idea would have been
stronger. My move gave Karpov a clever defense, and suddenly he was one move
from reclaiming his title. But under pressure from the clock, he missed the
best move (though our exchange of errors would not be discovered until well
after the game), and the momentum was still with me. -- Kasparov, "How Life

Be4 Kg8 39. Qb5 Nf8 40. Qxb6 {Karpov's best opportunity to defend had passed,
and my forces surrounded the black king. I regained my sacrificed pawn with
interest, and by the time we reached move 40, ending the time scramble, my
position was clearly superior. The game was adjourned until the next day with
the title still up in the air. It was going to be a long night. Getting a good
night's sleep before the game had been wise, but now there was work to do.
Thirteen pieces were still on the board, including queens, too much material
for definitive endgame analysis. I had an extra pawn, but with such limited
material, Karpov had definite chances of a draw. A lot of chess was still
ahead. -- Kasparov, "How Life Imitates Chess"} Qf6 41. Qb5 Qe7 {[#]} 42. Kg2 {
The best news was that I could play this position forever, maneuvering around
to provoke a mistake by my opponent. Black would be tied down on defense the
entire time, and Karpov knew it. The prospect of such prolonged torture took
its toll; I could see it in his eyes when he walked on the stage a few minutes
after I did. His fatalistic expression told me that he had already lost the
game psychologically, which boosted my confidence. -- Kasparov, "How Life
Imitates Chess"} g6 {The maneuvering began. I remember being surprised when
early on Karpov made a pawn push that my team and I had established as bad for
black's defensive chances. Apparently Karpov and his team disagreed with our
analysis, or perhaps it was a psychological error. Sometimes the hardest thing
to do in a pressure situation is to allow the tension to persist. The
temptation is to make a decision, any decision, even if it is an inferior
choice. And Karpov's move made the position more concrete, reducing the level
of uncertainty. But in my favor, his structure was now fixed, presenting me
with clearer targets. Convinced of the quality of our analysis, I took
Karpov's significant deviation from it as a mistake, not a potential
improvement, further increasing my confidence. -- Kasparov, "How Life Imitates

I began to feel the win was in the bag. Karpov's pieces were pinned up against
the wall, and a little more maneuvering would lead to decisive material gain.
Later I heard that FIDE President Florencio Campomanes was busy calling a
special meeting in another room to decide how to handle the closing ceremony,
which was scheduled to be held on the same day. But it still looked as if this
game could last forever; what was to be done? Two crises were averted at once
when someone ran into the meeting room to announce, "Karpov resigned!" It was
without question the loudest and longest standing ovation I had ever received
outside my native country. The theater thundered as Spanish television cut
from futbol to broadcast the conclusion of the match. I had done what Karpov
had failed to do in 1985: won the final game and drawn the match to retain my
title. This time I would have a good, long time to enjoy it. -- Garry Kasparov,
