{Precisely one year ago, I stated that GM Hikaru Nakamura winning the
Tradewise Gibraltar Chess Festival might become the third certainty in life
after death and taxes. Although 2018 saw Nakamura's reign come to an end as GM
Levon Aronian took home the £25,000 grand prize after a four-person playoff,
the American claimed the tournament's best performance rating. Five
consecutive wins preceded five straight draws, with Nakamura looking
invincible in the first half. His ability to overcome lower-rated grandmasters
with relative ease makes him a favorite in any open. In the following game,
Nakamura throws out his normal repertoire in favor of "just getting a
position" from which he smoothly outplays his overmatched opponent.} 1. e4 c6

opponent by over 200 ELO, Nakamura likely wanted to avoid the well trodden

9. d4 e6) 5. Qxf3 e6 6. Be2 g6 {Nakamura continues to wait, sitting
comfortably behind his brick wall of a center. Black need not commit to an

can castle to either side of the board. Generally speaking, castling long
provides White the option of launching his kingside pawns, whereas castling
short reduces the likelihood of a Black counterattack.}) 7... Bg7 {[#]} 8. Rd1
{According to my database this is a novelty, albeit one that I am not fond of.
Based on Perez Ponsa's move order, it appears he wanted Nakamura to push his
central pawns to dark squares. Because of this decision, he was left with a
weak bishop on e2.8. d3 was better, especially because it saves two tempi in
the event 8...d4 is the response.} (8. d3 d4) 8... d4 9. Nb1 Ne7 10. d3 c5 11.

playing this move signals a one-sided thought process, since it allows Black a
straightforward queenside initiative beginning with} b5 {. Black has firm
control over the f5 square, meaning moves like Qb6 are imminent. Moreover,
Black can immediately reply with 14...e5, with similarities to the game. A
critical distinction, though, is that Black will find it difficult to swap
dark-squared bishops.} (14... e5)) ({Facing a fianchetto,} 14. h4 {should
always be considered.}) 14... e5 (14... b5) 15. Bd2 Rb8 {Nakamura's aim is
clear: expand on the queenside and lock the knight in on a3. From a strategic
standpoint, Black needs to establish control over the c4 square. This will
require the obvious ...b5 push, in addition to the less obvious Nc8-d6
maneuver. By rerouting the knight do d6, Black will then be ready to play a
combination of ...b4, c4, and f5.} ({Too early is} 15... f5 {which allows the
light-squared bishop to gain access to a more impressive diagonal. In fact,
there's a choice available:} 16. exf5 (16. h4 f4 17. Qh3 h5 {doesn't shut down
the bishop because of} 18. g4 $1) 16... gxf5 {certainly gives Black a stronger
center and the potential for an attack, but the two bishops can immediately
begin to prod at Black's setup with moves like Bg5, Bf3, or even Bh5.
Alternatively, 16. h4 f4 17. Qh3 h5 comes close to locking in the bishop once
more, yet 18. g4! breaks the position open in White's favor.}) 16. Rf1 ({
At the moment there is no need for the rook to be on f1. It was defending the
bishop on d2 and always had the option of swinging to the file later. This
imprecise move was an evident tell that Nakamura was prepared to meet.} 16. f4

allowed the knight to escape.}) (16. Nc4 b5 17. axb5 axb5 18. Na5) 16... b5 17.
axb5 axb5 {This is the game's critical moment. White has a handful of options,
though the optimal continuation is far from clear. Perez Ponsa erred here,
perhaps underestimating Nakamura's impending stronghold over the dark squares.
[#]} 18. f4 $2 {For all intents and purposes, this is the move that cost Perez
Ponsa the game. Such an assertion feels preposterous given that White is in
prime position to play f4 and his position looks very solid. White has two
bishops, the rook on f1 will be situated on a semi-open file, more space is
gained, and, otherwise, what would the plan be? Yet as GM Yasser Seirawan
taught me years ago, chess is a game of squares. The vacated e5 square will be
occupied by a Black knight, simultaneously dominating the enemy bishop and
controlling the vital c4 square.} ({White's worst piece is the caged knight on

structure. Black is unable to fix it by playing 21...Nd4 22. Bxd4 cxd4 because
the pawn on e5 would fall.} Nd4 22. Bxd4 cxd4) ({White also had the
opportunity to take over the h-file with} 18. h4 $5 {but this would initiate a

22. g4 {What a dynamic. Black will operate on the queenside and try to dodge
the White attack. Foreseeing all of the consequences of 18. h4 is improbable,
and even at this position it is hard to determine whose future is brighter. [#]
}) 18... Bh6 $1 {Perez Ponsa must have missed this possibility, pinning the
f-fpawn and forcing an exchange of bishops. This is vital, for two bishops
versus knight and bishop is a superior minor piece scenario than a passive
bishop versus a strong knight. The reason the knight becomes so powerful is
because of the ensuing trade. White runs out of pieces to challenge the e5
square.} ({Logical is the combative} 18... f5 {but Nakamura's show of
restraint is admirable and preferable. Whereas in the game he did not have to
fear much counterplay, this continuation invites ideas such as h4-h5 and the
bishop should find some freedom along the light squares.}) 19. Qh4 Bxf4 20.
