Chess, like economy, is about trying to have a competitive advantage over your opponent. This is generally achieved by being the better player. In a more specific sense, you will accomplish it by preparing your openings well, in order to get an informational advantage. To this end, the best openings are these, where the truth is elusive and cannot easily be recognized by the naked eye (by your unprepared or less well-prepared opponent). For that reason, I have been pretty successful with the Hedgehog, as it sometimes appears to defy conventional chess logic and can only be understood on a more abstract level.

While the Caro-Kann mainline is clearly less complicated than the Hedgehog, it is yet deep enough to harbor optical illusions, which work in Black’s favor. When I worked my way through the main lines, I was constantly confronted with engine evaluations between =+ and -/+ where I wouldn’t have initially expected it. The reason for that are White’s many actual or potential weaknesses, with the pawn on h5 being the most prominent one. The following game is a good example. Please have a look at where I indicate =+, -/+ and -+. If you are under 2400, I promise, it will be hard to understand these evaluations without a second thought.

Originally, this game belonged to a series of model games I am presenting in my seminar “Das Schachuniversum – Teil 2”. As there are more than enough of such games, I decided to publish it here on my website.

1. e4 c6 2. d4 d5 3. Nc3 {White has many options here, with 3.e5 being the
most important alternative. However, the question whether the Caro-Kann is
something for you depends upon your appreciation of the
position type resulting from White's main line. Do you feel a passion for it like I do, or does it leave you cold?} dxe4 4. Nxe4 Bf5 {[#] For me,
the Capablanca Variation is more attractive than both 4..Nd7 and 4..Nf6.} 5.

tried here, of which none could endanger our opening.} h6 7. Nf3 Nf6 (7... Nd7

know,} 8. Ne5 Bh7 {is not to be feared, as White's proud knight will be
challenged by Nd7.}) 8... Bh7 9. Bd3 Bxd3 10. Qxd3 e6 11. Bd2 Be7 12. O-O-O {
[#]} O-O {It was in the 90s, when the Capablanca Variation had been revived by
the plan to castle short-side. Castling long-side is also possible, but less
ambitious, as Black is deprived of his attacking potential. Also, the kingside
pawns might become weak without king protection.} (12... Nbd7 {leads to the
main tabiya of 7..Nd7. Also there, the idea is to castle short-side. By
castling immediately Black can try exploit having chosen a different move
order. Objectively, that's not an advantage. It's just different positions.})

are back on main line territory by transposition.} c5 $1 {The most important
pawn move of this structure. Basically, it unleashes Black's entire army.} 15.

16... Qc7 $15 {[#] Please have in mind what I wrote at the beginning of this
article. If you asked 100 people on the street, probably 90 wouldn't see any
particular problems and some might even favor White's position, as from a mere
optical perspective, his space advantage looks attractive. However, after
studying this position, you will stumble upon White's problems. His h-pawn is a
liability in most endings. The knight on g3 is poorly placed by itself and
additionally blocks the g-pawn, which would be needed for an attack.
Additionally, White's g- and f-pawn are potential targets, as they lack king
protection. On top of this, and very relevant for this game, White's king is not defended by too many pieces
and Black's forces can easily step up the pressure on the queenside.} 17. Bc3 $2
(17. Ng4 $15) 17... Rfd8 18. Ng4 Nd5 $1 $17 {[#] That's s an improvement over
18..Nxg4? which happened in Xie-Brunner, Bern 1995. The knight on g4 doesn't
contribute much, while the centralized black mustang is a force to reckon with.
Again the same question: If you asked 100 people on the street, how many would
discern a clear black advantage?} 19. Be5 Qc6 20. Rhe1 $2 {Most probably, that
is already more than White's position can take.} (20. f4 Rac8 21. c4 Nb4 22. f5 Bg5 $17

22. Rxd5 Qxd5 23. f3 Rd8 $17 {White managed to exchange off the Nd5, but the
d-file now belongs to Black. Additionally, White's h-pawn is weak and if
anything, Back could just start marching with his queenside pawns.}) 20... Rac8
$19 {[#] Would the man on the street agree to this verdict?  I don't see a way
for White to avert disaster on the squares c2, b2 or c3 in a satisfactory
manner. Black's idea is to play 21..Na4 and then chase the Be5 away from the
long diagonal by means of f6 and e5.} 21. c3 (21. Ne3 Nxe3 22. Qxe3 Qxg2 $19) (

Rxd1 Qxg2 $19 {Back just nets a pawn for nothing. Can you see how White's many
weak pawns on the kingside added fuel to Black's queenside attack?
Interconnectedness is not only a phenomenon of reality itself (imho), but also
very important on the chess board. White's position was simply over-extended.
He either had the choice to jettison a pawn or to stick to his material and
feel the whip coming down on his king.}) 22... f6 23. Bd4 {[#]} Ndxc3 $1 {
