This next commentary game is a nice example of how strategic, positional play in the English Opening can lead to a tactical finish, sometimes rather quickly. With these master games, I save interesting ones periodically and then get to them whenever I can. GM Alejandro Ramirez recently had a disappointing 2020 U.S. Championship, so I decided now would be a good time to look more deeply at this instructive and clean win of his over FM Aleksey Sorokin, as compensation.

1.c4 Nf6 2.Nc3 d5 this simplifies White's opening choices, as it makes
little sense not to exchange the c-pawn for Black's central d-pawn. 3.cxd5 Nxd5 4.g3 the most popular continuation. The more flexible Nf3 also scores
as well, around 57 percent in the database. e5 staking out territory in the
center (which Nf3 would have prevented). 5.Bg2 forcing Black to choose what
to do with the Nd5. Nb6 preferred and best scoring option (around 50 percent)
. 6.d3 still avoiding committing the other knight. Moving the d-pawn seems
necessary in any scenario for White. Be7 7.Be3 the bishop development to e3
is a standard idea in some lines of the English. Here, f4 and g5 are out and
d2 would be more passive. The Black king's knight is also on b6 rather than f6
as normal, so cannot harass it. 0-0 8.Rc1 activating the rook on the
half-open c-file. Re8 9.Nf3 the knight is finally developed. 9.a3
is often played here. 9...Nc6 the e-pawn must be protected. 10.0-0 Bf8
overprotecting the e-pawn and choosing to give the bishop a defensive role on
the kingside, which is lacking the usual protection of a knight. 11.a4
White has played a variety of moves here. Normally one would expect an a-pawn
thrust to be more consistent with a White rook on a1. One recent high-level
alternative: 11.Bg5 Qd7 12.a3 h6 13.Bd2 Qd8 14.Ne4 a5 15.Nc5 a4 16.Qc2 Ra7 17.Rfe1 Nd4 18.Nxd4 exd4 19.e4 dxe3 20.Bxe3 c6 21.Ne4 Be6 22.Bc5 Ra8 23.Bxf8 Rxf8 24.Nc5 Bc8 25.Re4 Re8 26.Rce1 Rxe4 27.Rxe4 Ra5 28.h3 Kf8 29.d4 Ra8 30.Re1 g6 31.Qd2 Kg7 32.Qf4 Nd7 33.Ne4 Ra5 34.Nd6 Nf6 35.Re8 Qd7 36.Rxc8 g5 37.Qd2 Ra6 38.Qb4 c5 39.dxc5 Rxd6 40.cxd6 Qxc8 41.Bxb7 Qxh3 42.Qxa4 h5 43.Qd4 Qd7 44.Bf3 h4 45.gxh4 gxh4 46.Qxh4 Qf5 47.Kg2 Kf8 48.a4 Qg6+ 49.Qg3 Qf5 50.b4 Nd5 51.Qg4 Qe5 52.Qc8+ Kg7 53.Qg4+ Kf8 54.d7 Ke7 55.Qe4 Qxe4 56.Bxe4 Nxb4 57.Bf5 Nc6 58.Kf3 Kd6 59.Kf4 f6 60.Be4 Nd8 61.Kf5 Kxd7 62.Kxf6 Kd6 63.a5 Ne6 64.a6 1-0 (64) Caruana,F (2835)
-Nepomniachtchi,I (2784) chess24.com INT 2020 11...a5?! Black blocks the
a-pawn's further advance, but this was not currently threatened. Perhaps it
was a deliberate invitation to exchange on b6 and give Black the two bishops,
although White seems to inflict enough structural damage to more than
compensate for that. 12.Bxb6 12.d4!? is the engine line and actually has
been played in a few games. The point is that exchanges on d4 favor White's
piece activity. exd4 12...Nc4 is what the engines give 13.Nb5 Nxe3 14.fxe3 13.Nxd4 Nxd4 14.Qxd4 Qxd4 15.Bxd4± 12...cxb6 13.Nb5
now White has b5 as an excellent outpost for the knight. Be6 this seems to
unnecessarily weaken the e-pawn, by blocking the Re8. 14.d4 now Black
cannot maintain the pawn on e5. e4 14...exd4 is the other option, which
likely will lead to wholesale liquidation: 15.Nfxd4 Bg4 16.Nxc6 bxc6 17.Bxc6 Bxe2 18.Qxd8 Raxd8 19.Bxe8 Bxf1 20.Kxf1 Rxe8= 15.Ne1 this is the
most challenging option for White, avoiding a piece exchange and activating
the strong Bg2. The knight will later emerge via g2. 15.Ne5 is less
ambitious and gives Black more play. Nxe5 16.dxe5 Qxd1 17.Rfxd1 Bb3 18.Rd4 Rxe5= 15...f5 15...Rc8!? may be better, but is a typical complicated
engine line. 16.Bxe4 Nxd4 17.Rxc8 Bxc8 18.Qxd4 Qxd4 19.Bxh7+ Kxh7 20.Nxd4= 16.f3 a forcing move which causes Black to go wrong. Bd5? this will
allow White to force a favorable structure in the center. 16...exf3 17.Bxf3 and White should have a comfortable game after e2-e3 and Ng2, but the engine
rates it as equal. 17.fxe4 fxe4 17...Bxe4 would give White too much of a
free hand in the center. 18.e3 White's d-pawn is now protected and passed,
while Black's isolated e-pawn requires defending. g6 Black needs to activate
his dark-square bishop. 19.Bh3 an illuminating move. White seizes a better
diagonal for his bishop, as the e4 pawn is doubly protected. This leaves the
Bh3 superior to its Black counterpart. Bh6 19...Be6? attempting to
exchange bishops does not work tactically. 20.Bxe6+ Rxe6 21.Qb3 Qe7 22.d5+- 20.Ng2 getting the knight back into the action, protecting e3 and
looking to go to f4. At this point White is strategically winning, as his
pieces are all better placed than Black's. Re7 21.Nf4 this is not as
forcing as some other possibilities. 21.Rf6! is the engine move, which
of course is not at all obvious. The point is that the rook threatens to go to
d6, while White can also play Qg4 and Rcf1, mobilizing his heavy pieces to
dominate. Nb4 22.Qg4± 21.Qg4!? with the idea of Qh4 also looks very
good. 21...Nb4 protecting the Bd5 again. 22.Qg4 Nd3?? Black makes a
bid for counterplay which fails to a tactic. 22...Bxf4 Black likely
hesitated to give up the two bishops, even though it was best for defense. 23.gxf4 23.Nxd5 Nxc1 23...Qxd5 24.Rc8+ Rxc8 25.Qxc8+ Kg7 26.Qf8#
White's control of the f-file pays off. 24.Qh4! with a double attack on
e7 and h6. 24.Nxe7+ Qxe7 25.Nc3 trapping the knight also should win. 24...Qxd5 24...Bf8 after the exchanges Black just ends up a piece down. 25.Nxe7+ Qxe7 26.Qxe7 Bxe7 26...Ne2+ 27.Kf2 27.Rxc1 24...Bxe3+ 25.Nxe3 Ne2+ 26.Kg2+- 25.Qxe7 Bxe3+ 26.Kh1 White now threatens Be6+ with
mate to follow. 1–0
