1. e4 { [%eval 0,0] [%csl Ge4][%cal Ge2e4] } 1... c6 $6 { [%eval 56,0] Inaccuracy. e6 was best. [%csl Gc6][%cal Gc7c6] } 2. d4 { [%eval 41,0] [%csl Gd4][%cal Gd2d4] } 2... d5 { [%eval 28,0] [%csl Gd5][%cal Gd7d5] } 3. Nc3 { [%eval 26,0] [%csl Gc3][%cal Gb1c3] } 3... dxe4 { [%eval 33,0] [%csl Ge4][%cal Gd5e4] } 4. Nxe4 { Nxe4 is favorable because it allows the play of Nxf6+, which prevents the
capture of the black knight's defenses on f6 and f3 and stops the white
knight from being taken on e4 (Ng8-f6-e4). 
It is obvious that Black can respond to Ng3 by playing e6 after Nd7. [%csl Ge4][%cal Gc3e4] } 4... Nd7 { [%csl Gd7][%cal Gb8d7] } 5. Ng5 { [%eval 11,0] This is an interesting move, with chances to blow Black off the Board. Even Kasparov got blown with a crushing knight sacrifice. Major threats Bd3 (1.12) leads to checkmate, threatens the black pawn on g6 [%csl Gg5,Rh6,Re6][%cal Ge4g5,Rh7h6,Re7e6] } 5... e6 { The best play after 5 is e6, since it threatens to play Ngf6 and h6
sooner hopefully. Would have been a waste of tempo placing the knight on
g5! [%csl Ge6][%cal Ge7e6] } ( 5... h6 $6 { This move seems logical, as Nxf7 doesn't work. However, White can get a
slight edge with Ne6! and can win quickly if Black makes a blunder. A
grandmaster lost to this trap. The e8-h5 diagonal is slightly weakened, and so is f7. The main line is Ne6! Qb6 (Wisely avoiding fxe6?? Qh5+ g6
Qxg6#) Nxf8 Nxf8 with two Bishops and a slight edge. [%csl Rh6][%cal Rh7h6] } 6. Ne6 $1 { 5... The white knight on g5 might advance to e6 in order to trap the
black bishop on f8. Would have been a horrible news for black! lets say for
example. 
h6 6. 
Ne6 Qb6 7. 
Nxf8, this is a daring and unexpected move, but it exploits the flaws
presented by h6. 
This is one of the Ng5 spots that opens the h5-e8 diagonal. [%csl Ge6][%cal Gg5e6] } 6... Qb6 { [%csl Gb6][%cal Gd8b6] } 7. Nxf8 { [%csl Gf8][%cal Ge6f8] } 7... Nxf8 { [%csl Gf8][%cal Gd7f8] } ) 6. Bd3 { [%eval 44,0] [%csl Gd3][%cal Gf1d3] } 6... Be7 { [%eval 54,0] [%csl Ge7,Gg5][%cal Gf8e7,Ge7g5] } 7. N1f3 { [%eval 45,0] [%csl Gf3,Gg5][%cal Gg1f3,Gf3g5] } 7... h6 { White is keen on the following sequence of move 
At move 6, White has the equality move Bc4: 
5... Qb6 followed by 0-0 then standard development with Nf6. The solution is
6. Bc4 Qb4+ 7. c3 Qxc4, giving Black a clear advantage. If you want to play h6 before Qb6, the issue disappears. Nothing to mind after Qb6 since h6 can then be played! 
Five... h6 six... Ne6 Qb6 seven... Bc4 (poor move) 
7. .. fxe6 In this case, following h6, we can see that Black has the option
of responding to White's Ne6 with his own Qb6. [%csl Gh6][%cal Gh7h6] } 8. Ne4 { [%eval 67,0] [%csl Ge4][%cal Gg5e4] } 8... Ngf6 { The threat of Nxe4 from Ngf6 is favorable, since it puts the white knight
on e4 in danger. Black should just continue with his standard development, [%csl Gf6][%cal Gg8f6] } 9. c3 { [%eval 21,0] [%csl Gc3][%cal Gc2c3] } 9... O-O { [%eval 42,0] [%csl Gg8][%cal Ge8g8] } 10. O-O { [%eval 33,0] The usual idea in the Caro Kann Karpov Variation; the c5 thrust! To try and break up white's center and to also provoke white to create additional weaknesses around the position. [%csl Gg1][%cal Ge1g1] } 10... c5 { Helpful, since it removes a guard from b4 when dxc5 threatens to play b4.
Both the difficulty to play dxc5 and the pawn's lack of movement from c5 to
c6 count as weaknesses of dxc5. 
Ne5 prevents the capture of the black bishop and gives d5's queen control of
c5 and e5, allowing her to better defend d3. [%csl Gc5][%cal Gc6c5] } 11. Ne5 { The benefit of cxd4 is that it poses a danger of playing 
Taking the white pawn with Nxe5 exposes its vulnerabilities: the pawn can no
longer play cxd4, which means that white is no longer in possession of the d4 square. 
Supporting the move dxe5 with nxe5 eliminates the danger of cxd4 and the
possibility of capturing the white pawn. 
Nxe5 forbids cxd4, which allows dxe5 to be played. 
Playing is what Idea Black has in mind. 
11... Bd6 12.1.. Nxe5 Problem 
Nxd6 is a valid move for White: 11... Bd6 
Solution cxd4 (13th) 
Fixing the issue with cxd4 before Bd6. After 13. Bxe4 Bd6, 14. Nxd6 is ruled
out. 14.. Knight wins on nxe5 
It is clear that following cxd4, Black has the option of playing Bd6 in
response to White's Bxe4. [%csl Ge5][%cal Gf3e5] } 11... cxd4 { [%eval 0,0] [%csl Gd4][%cal Gc5d4] } 12. cxd4 { [%eval 31,0] [%csl Gd4][%cal Gc3d4] } 12... Qb6 { The benefit of cxd4 is that it poses a danger of playing

11... Bd6 12.1.. Nxe5 quite a "Problem" 
Nxd6 is a valid move for White: 11... Bd6 
Nxd6 cxd4 dxe4 dxe4 dxe4 dx 
Solution cxd4 (13th) 
Fixing the issue with cxd4 before Bd6: 
12. cxd4 Nxe4 
After 13. Bxe4 Bd6, 14. Nxd6 is ruled out. 
14.. Knight wins on nxe5 
It is clear that following cxd4, Black has the option of playing Bd6 in
response to White's Bxe4. [%csl Gb6,Gb2][%cal Gd8b6,Gb6b2] } 13. Nxf6+ { [%eval 12,0] [%csl Gf6][%cal Ge4f6] } 13... Bxf6 { [%eval 62,0] [%csl Gf6][%cal Ge7f6] } 14.
