Time Control: G/40 +5
Time Control: G/40 +5
[D00: 1 d4 d5: Unusual lines]
1.d4 c6
Black plays c6 with the idea of transposing to a modified Caro-Kann (2.e4) or Slav (2.d4).
2.Nf3 Nf6 3.Nc3
Blocks White's c-pawn.
3...d5
Prevents e4 & transposes to a Slav-like Defense.
4.e3
Limits White's bishop's mobility.
4...Bf5
Seizes the b1-h7 diagonal (often an important one for White in Queen's Pawn openings).
5.Bd3 Bxd3
Trades a potentially “bad” bishop for White's good bishop.
6.Qxd3 e6
Black appears to be behind in development, but his 'undeveloped' bishop is on a nice diagonal, while White's bishop is hemmed in.
7.0–0 Nbd7 8.Bd2 Nb6 9.a3

[Controls b4]
9...Nc4
10.b4
Even though it “undevelops” a piece, it may have been better for White to play Bc1, guarding the b-pawn. Pushing the pawn past Black's knight yields a fine outpost.
10...b5
Keeps White from gaining a space advantage on the queenside.
11.Ne5
Wants to trade for Black's well-placed knight.
11...Nxe5
The goal is to secure a strong outpost for his knight, not trade for the bishop. If White drives the knight away with b3, Black eyes the other side of the d-pawn with Nd3 followed by Ne4.

11.Ne5

11...Nxe5
[11...Qb6 12.Qe2=]
Black does not like the suggested move of Qb6, as that would allow an exchange of knights a pawn taking over the c4 square (which Black wants to reserve for his knight). It won't take long for Black to maneuver his other knight to the strong outpost on c4... and then it will be difficult for White to force him out.
12.dxe5²
[White has new doubled pawns: e3+e5]
12...Nd7
[Manoeuvre Nf6-d7-b6-c4]
13.f4 Nb6
tChess still evaluates the game to be virtually even, but Black has a strong positional advantage, which will become clear once the computer's “horizon” is extended...

[14.a4!?²]
a4 would be an attempt to create some needed counterplay for White.

14...Nc4³
[Black threatens to win material: Nc4xa3. A classical outpost]
15.Bc1
[15.Ne2!?³ is worth looking at]
tChess also suggests Ne2, but that move would allow the knight to fork queen & rook (Nb2), winning the exchange. This would essentially trade one advantage (positional) for another (material, at least in the long run). Then again, it would open up White's queenside and possibly allow some counterplay. Could be that this is one of those situations where a well-placed knight is actually worth more than a rook...
15...a5µ
Black plans to open the queenside hence allowing more infiltration of his pieces.

16...axb4 17.axb4 Bxb4 18.Ne2 Ba3
19.Nd4 Qb6
Pins the knight, guards the c-pawn, places another active piece on the queenside.
20.Be3
White's bishop is playing an important defensive role, guarding b2 from a knight fork, so Black wants to remove the guard.
19.Nd4 Qb6
Pins the knight, guards the c-pawn, places another active piece on the queenside.
20.Be3
[¹20.exd5!? exd5 21.Kh1µ]
Setting up a potential discovered attack on the queen seems like a good idea, however it allows the knight fork on b2.
20...c5–+
Prevents the potential discovered attack, forces the knight to move (or be lost), preserves the knight fork.
21.Nb3
Prevents the potential discovered attack, forces the knight to move (or be lost), preserves the knight fork.

Black missed a fork that would have won the rook, but it's still an easy win from here.
