B18: Classical Caro-Kann: 4...Bf5 sidelines
[...] 1.e4 c6 2.d4 d5 3.¤c3 dxe4 4.¤xe4 ¥f5 5.¤g3 ¥g6 6.¤f3 ¤f6 7.¥c4 e6 8.O-O ¤bd7 a solid move, but it allows White to establish the Bf4. (8...¥d6) 9.¥f4 ¤b6 not a good decision. I waste time in the opening by driving my opponent's bishop to a better square, while moving the same piece twice.
9...¥e7 10.¦e1 O-O 11.¤h4 £b6 12.¤xg6 hxg6 13.¥b3 ¦fd8 14.c3 c5 15.¤e2 e5 16.dxe5 ¤xe5 17.£c2 ¤d3 18.¦ed1 c4 19.¥e3 cxb3 20.axb3 £b5 21.¤d4 ¦xd4 22.¥xd4 ¤f4 23.¦xa7 ¦xa7 24.¥xa7 Djacic,N-Maric,A (2407) Cetinje 2009 0-1 (34)10.¥d3 White has an active position, notes Komodo via the Fritz interface. 10...¤bd5 hitting the bishop and centralizing the knight, but I am still under-developed. Again, White's bishop is driven to a better square as well. (10...¥d6 11.¥e5 O-O) 11.¥e5 ¥d6 a little late with the idea and not really helpful for me. Unfortunately, taking with the bishop on e5 would simply give White a strong e5 pawn and kick the Nf6, gaining a tempo. With the dark-square bishop gone, I also would have more trouble covering the dark squares on defense. The bishop is actually something of a liability on d6 for me, as the Qd8 is tied to its defense.
11...b5 is the engine's recommendation of a prophylactic move, to help preserve the Nd5 on its square. Whenever Black puts a knight on d5 in this variation, if White can advance a pawn to c4 to kick it off the square, it's not very well placed. 12.h4²
11...¤d7!? might be a better version of the idea to exchange the Be5.12.¦e1
12.c4 would give White the initiative. 12...¤e7 13.¥xg6 hxg6 14.£b3 ¦b8²12...O-O removing the king from the e-file, very important for tactical reasons as well as developmental. 13.£d2 my opponent continues to play decent but somewhat slow moves. 13...b5 here I recognize the importance of defending the Nd5 outpost and implement the prophylactic idea (a bit late).
13...¥e7 is also an option, acknowledging that the trade on e5 will not happen with the bishop and allowing ...Nd7.14.a4 (14.c3 ¥e7) 14...a6
14...b4 is a superior continuation, gaining space. 15.c4 bxc3 16.bxc3 ¥e7 and now if 17.c4 ¥b4³ (17...¤b4 also works.)15.h3 presumably done to prevent ...Ng4.
15.axb5 is probably the most challenging way to continue, but after a series of piece exchanges White will not have enough material to push an attack. 15...cxb5 forced. (15...axb5?16.¦xa8 £xa8 17.¥xd6+−) 16.¥xd6 £xd6 17.¤e5 ¥xd3 18.£xd315...¦e8 (15...£c7!?16.¥xd6 £xd6 17.c3) 16.¤e4 this allows for simplification into a drawish position. 16...¤xe4 17.¥xe4 ¥xe4 18.¦xe4 ¤f6 this seemed the obvious move at the time, although it would allow White to try to create something on the h-file with Rh4.
18...f6 is forcing with the Bd6 and also takes away the g5 square from White's knight. 19.¥xd6 £xd6 20.¦ae1 White can try to pressure the e-pawn but without prospects for success. 20...¦e7 is the safe response, leaving e8 open for the other rook.19.¦ee1 (19.¦h4 £e7) 19...h6 I correctly evaluated the position here as having no winning prospect for myself, with any chances on my opponent's side, so accepted a draw. (19...¥e7)
