B16: Caro-Kann: Bronstein-Larsen Variation 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Nxf6+ gxf6 6.Nf3 although this is the second most popular move
and is played at high levels over-the-board, theory mostly ignores it in favor
of 6. c3. Bg4 why the previous move is considered theoretically less
desirable. Normally the bishop has to go to f5 instead. 7.Be2 e6 8.0-0 Qc7
Bd6 is more popular here, although both prevent White from playing Bf4. 9.Nh4 White scores 75% from here. Bxe2 10.Qxe2 Nd7 11.c4 0-0-0 obligatory, as
the king has nowhere else to go. 12.Rd1 White has tried a lot of things in
this position, but 12. g3 is by far the most played, with the idea of shutting
down Black's play on the g-file. Here are two games where Black managed to
draw. 12.g3 h5 12...Rg8 13.d5 Qe5 14.Be3 Qe4 15.dxc6 Ne5 16.cxb7+ Kxb7 17.Qh5 Qxc4 18.Rad1 Rxd1 19.Rxd1 Rg4 20.Ng2 Qc2 21.Rc1 Qg6 22.Qxg6 Rxg6 23.f4 Nc6 24.Rd1 Be7 25.f5 Rg8 26.Kf2 e5 27.Kf3 Kc7 28.Rc1 h5 29.b3 a5
1/2-1/2 (29) Asis Gargatagli,H (2431)-Alvarez Pedraza,A (2551) Barcelona 2011 13.d5 Re8 14.dxe6 fxe6 15.Bf4 Bd6 16.Bxd6 Qxd6 17.Rad1 Qc7 18.Rd2 Ne5 19.Rfd1 Kb8 20.b3 a6 21.Rd6 Qb6 22.Kg2 Qa5 23.Kh1 c5 24.Nf3 Nc6 25.Kg1 h4 26.Rxe6 Rxe6 27.Qxe6 Talla,V (2335)-Jankovec,I (2240) Czechia 1998 1/2-1/2
(41) 12...c5 this is a standard break in the Caro-Kann main line, the idea
being to help activate Black's pieces. With Black castled queenside it
requires a little more bravery. 13.d5 White would of course welcome an
exchange on d5, leaving Black with no central pawns and a horrendous pawn
structure on the kingside. Ne5 13...Bd6 is suggested by Houdini. Black is
falling behind in development and needs to generate kingside threats. 14.dxe6 is not a refutation because of fxe6 15.Qxe6 Bxh2+ 16.Kf1 Be5 14.Bf4 Bd6 15.dxe6 fxe6 16.Bxe5 fxe5 at this point it's clear that Black's shattered
and vulnerable pawn structure will be the central focus of the remainder of
the game. 16...Bxe5 appears somewhat better, although still difficult for
Black, as the Bishop can be a target as well on e5 and has few places to go. 17.Nf3 17.g3 Qf7 with the g-file closed after the previous move, the
f-file is the only possible avenue of attack. This seems to have been the
rationale for taking with the pawn on e5, in order to have it influence f4. 18.Rd2 Rhf8 19.Kg2 Rd7 19...Bc7 is Houdini's recommendation. 20.Rxd8+ Rxd8 21.Re1± 20.Rad1 Rfd8 21.Qe4 White's pieces are more mobile and
threatening than Black's. At this point Black focuses on defense, in the hopes
that White cannot find a way to practically exploit his weaknesses. Kc7 22.Rd3 Qh5 23.Rb3 b6 24.Ra3 a5 25.Rad3 Rg7 26.h3 Rf7 27.R1d2 Rfd7 28.a4 Rf7 having achieved a strong defensive setup, Black shuffles his rook while White
attempts to break through. 29.Rf3 Rfd7 30.Rfd3 Twofold repetition. Rf7 31.b3 White can afford to make small improvements and move closer to the time
control, as Black has no threats. Rfd7 32.Nf3 now White starts to marshal
his forces, returning the knight from the rim. Qf5 33.Re2 Rf7 34.Rde3 Rdf8 35.Qxf5 White decides to head for the endgame and pick up a pawn in the
process. 35.Nxe5?! does not work due to Qxf2+ 36.Rxf2 Rxf2+ 37.Kg1 Rf1+ 38.Kh2 R8f2+ 39.Qg2 Rxg2+ 40.Kxg2 Rf5= 35...exf5 36.Nxe5 Rg7 37.f4 h5 38.h4 Rfg8 39.Rd3 Re8 40.Rde3 Rge7 41.Kf3 Re6 42.Rd3 this deliberately
invites the exchange on e5. Bxe5 43.Rxe5 Rxe5 44.fxe5 Rxe5 White has given
back the pawn in return for a dominant king. 45.Kf4 Re4+ 46.Kg5 Rd4 47.Re3 Kd6? Houdini (via the Frtiz interface) gives this a question mark, as it
facilitates White's win. 47...Rg4+ would allow Black to control the g-file
and prevent the loss of both kingside pawns without compensation. 48.Kxf5 48.Kxh5?! Kd6 48...Kb7± 48.Kxf5+- Kd7 49.Kg5 1–0
