For Caro-Kann players of either color, this game holds a lot of interest, since a number of typical themes appear. The results of the f-pawn advance for White and the decision to execute a pawn break on c5 for Black are perhaps the most important strategically, although other common structures and ideas are contained in the game. The tactical threats (some executed, others not) are also important to pay attention to, especially what White could have done with a bishop on h2.

1.e4 c6 2.d4 d5 3.Nd2 this move has little independent value, as Black
almost always takes on e4 in response. However, an alternative is ...g6
followed by ...Bg7, in which case White will follow with c3, blunting the
pressure on the long diagonal. dxe4 4.Nxe4 Bf5 the Classical Caro-Kann. 5.Ng3 Bg6 6.Nh3 an unusual choice. The knight normally goes to f3 and the
development N1e2 used to be another popular significant option. The text move
is obviously offbeat, but it scores well (58 percent) and has been used in
some recent high-level games. Nf6 7.Bc4 7.Nf4 would transpose to the N1e2
lines. 7...e6 8.0-0 Be7 8...Bd6 is often used in the N1e2-f4 lines to
fight for the f4 square and is the normal choice here as well. The text move
indicates that Black in this game may have had a greater concern for the h4-d8
diagonal and the g5 square. Here's a recent game that parallels White's plan
in the main game, using the f4 advance: 9.f4 Qc7 10.Kh1 0-0 11.f5 exf5 12.Nxf5 Nbd7 13.Nxd6 Qxd6 14.Bf4 Qb4 15.Bb3 a5 16.c3 Qb6 17.Bd6 Rfe8 18.Nf4 Be4 19.Nh5 Bg6 20.Nf4 Be4 21.Nh5 Bg6 22.Nf4 Be4 1/2-1/2 (22) Rozentalis,E
(2604)-Prohaszka,P (2599) Austria 2015 9.f4 now out of the database,
although more because of Black's unusual bishop move. The text move is also
usually played in response to ... Bd6 (as shown in the game quoted above). The
f-pawn advance is a logical follow-up to Nh3 as an independent line, as White
takes advantage of the f4 square being open (i.e. not occupied by a knight).
It also influences g5 and e5 to White's advantage. 9.Nf4 is usually where
the knight goes. 9...Qd7 this doesn't appear to be a bad move and
reinforces f5. However, it blocks the Nb8's development temporarily and the
f-pawn's advance is not to be feared. 9...0-0 10.f5 exf5 11.Nxf5 Bxf5 12.Rxf5 c5= 10.Kh1 this gets the king off the now-weak g1-a7 diagonal and
removes future potential tactics involving exchanges on d4 or c5. However,
it's also a bit slow and should allow Black to fully equalize. 10.Be3
played immediately should save a tempo and cover the diagonal. 10...0-0 10...c5!? whenever Black can get this pawn break in effectively without
king safety issues, it's normally a good idea. White doesn't appear to have
anything useful to do in response. For example, the engine can only come up
with 11.f5 exf5 12.dxc5 Qxd1 13.Rxd1 0-0= 11.Be3 this reinforces d4
and helps restrain ...c5. However, now that the king is off the diagonal, it's
not the most effective use of White's time. 11.Ng5 would seem more to the
point here, again logically following up on the presence of the Nh3. Otherwise
the knight is effectively doing nothing. Chasing it away with h6?! would
simply waste a tempo helping the knight to a better square, from where it
could then go to e5 (a much better square). 11...c5 White is now better
positioned to combat this pawn break. 11...Na6 gets the knight into the
game and White has nothing better than to exchange it. This shatters the
queenside pawn structure, but in Black's favor are the two bishops and a
semi-open b-file. 12.Bxa6 bxa6 Komodo 8 gives Black a small plus here.
Black's pieces are, in addition to the above points, better coordinated. 12.f5 White chooses to try for some action on the kingside rather than trade in
the center, which would lead to a more simplified position: 12.dxc5 Qxd1 13.Raxd1 Bxc2 14.Rc1= although the engine rates this position as equal,
White seems to have the easier position to play, at least for the short term. 12...Bxf5 12...exf5 13.dxc5 Qc8 would preserve the Bg6, unlike the text
move. Although the bishop is more of a "big pawn", it does well as a defensive
piece on the kingside and is certainly no worse than the Nh3. 14.b4 14.Nf4 Bxc5 14...Rd8 15.Qe2 Nc6= 13.Nxf5 exf5 14.dxc5 Ng4 Black at this
point has achieved equality and just needs to complete her development. The
text move is a nice way for Black to threaten the bishop and occupy a rare
advanced outpost on the kingside. 15.Bg1 g6 Black should not be afraid to
enter into this type of pawn structure when necessary, in this case to protect
the advanced f-pawn. The dark square weakness can be covered by the bishop,
while White's bishop is in no position to exploit it. 16.Bd5?! this looks
overly aggressive. White needs to be careful about the weak c-pawn, which is
easily attacked again, and also needs to bring the Nh3 into the game. 16.b4 a5 17.c3= 16...Qc7 17.b4 the difference with the earlier variation is
that the Qc7 is now pressuring c5 already. Also note the threat to h2 from the
knight and queen, which means the Bg1 cannot currently move without allowing a
mate. Nc6 Black finally has all her minor pieces developed, and to effective
squares. The queen's rook will also go to a nice square on d8. 17...a5!?
would more directly attack the exposed queenside. 18.c3 axb4 19.cxb4 Bf6 20.Rb1 Nc6 and Black now has the initiative, for example 21.Qb3 Bd4 18.Rb1 Rad8 19.c4 b6 Black has a number of reasonable choices here. 19...Bf6 preparing ...Be5 would redeploy the bishop effectively. 20.Nf4 White
wastes no more time in getting her knight back into the game. bxc5 21.bxc5
The doubled c-pawns may be a long-term weakness, but they're also passed pawns.
White's pieces are also now working together much better. Rb8?! Black may
have done this just on general principles, without looking at the tactics
fully. If she could recapture on b8 with the rook, that would certainly help
her position. Unfortunately it doesn't work out that way. 21...Bg5!? 21...Rc8!? would free the d8 square for the other rook and also line up on
the weak pawns. 22.Rxb8 Nxb8 ugly, but better than the alternative. 22...Rxb8 the main problem with this is that now when the White bishop goes to h2,
it has targets on both c7 and b8. 23.h3 Nge5 23...Nf6 24.Bh2 Qd7 25.Bxc6 Qxc6 26.Nxg6 hxg6 27.Bxb8± 24.Bh2 Bf6 25.Nd3 Re8 26.Qa4± 23.h3 Ne5 24.Re1 White brings her rook to a more effective file and generates
additional potential tactical problems for Black, now that the e-file is under
pressure. The Qc7 is a bit overloaded, as it cannot protect the Ne5 and
support an exchange on c5 at the same time. Bh4 Black's best option, getting
the bishop off the e-file and gaining a tempo with the attack on the Re1. 25.Re2 Nbc6 26.Bxc6 this dissipates some of White's pressure. The knight will
now also get off the e-file. 26.Bh2± still looks very effective. 26...Nxc6 27.Qd6 Qc8 Black naturally does not exchange on d6, which would create
two monster passed pawns for White. 28.Nd5 this position is probably what
White was looking at when she decided to exchange on c6. She still has an edge,
but with fewer pieces on the board there are less attacking chances. Re8 29.Rxe8+ Qxe8 with the additional exchange, Black probably was looking to head
into an endgame with a small disadvantage, but with good drawing chances. The
c-pawns look like they can be blockaded effectively. 30.Nc7?! the idea
behind this move is not clear to me. In the game, it results in Black's queen
moving to a much more effective centralized position, without generating any
evident threats. 30.Bf2 would be a clever tactical way to improve White's
position and get the Black bishop off the h4-e1 diagonal. The bishop has to
protect f6 due to the fork threat from the Nd5. 30...Qe4= 31.Qd5 Bg3
the bishop is now free to move and attacks the Nc7 "backwards" along the
diagonal. 32.Nb5 Qe1 with the threat of ...Bf2 33.Nd6? White chooses
to counterattack with a threat to f7, but she runs out of threats first,
losing the game. 33.Nd4 is the necessary defensive move. Nxd4 34.Qxd4= 33...Ne5! holds everything together for Black. 34.Qa8+ this starts a
long sequence where Black's king is chased almost the entire length of the
board, but eventually finds refuge. 34.Nxf5 gxf5 35.Qd8+ Kg7 36.Qg5+ Ng6-+ is the best try for White, but still leaves Black winning. For example 37.Qxf5 Be5 38.Qf2 Qc1 39.c6 Qxc4 and Black's material advantage is
decisive. 34...Kg7 35.Ne8+ Kh6 36.Nf6 Bf2 Black had to calculate
everything precisely to proceed with this move, but saw correctly that White
would not be able to deliver mate or get a perpetual check. 37.Qf8+ Kg5 38.Nxh7+ Kf4 39.Qh6+ Ke4 40.Ng5+ Kd3 White has run out of moves and mate on g1
is coming. 0–1
