B19: Classical Caro-Kann: 4...Bf5 main line
1.e4 c6 2.d4 d5 3.Nd2 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6 6.h4 h6 7.Nf3 Nd7 8.h5 Bh7 9.Bd3 Ngf6!? it's hard to see how this helps with Black's development
10.Bxh7 Nxh7 11.Qe2 e6 12.Bd2 Qb6 13.0-0-0 0-0-0 14.Ne5 Nxe5 15.dxe5 Bc5 16.f4?! probably not the best move, and with a horrible plan in mind [16.Ne4 Bd4 17.Bc3 despite being 3 ply away, I struggled to see this move, which is probably why I didn't play this line 17...Bxc3 18.Nxc3?! ]
16...Rxd2! Black will easily win back the exchange .. or more [16...Rd5 would have also been good]
17.Kxd2? at the time I thought this was quite brave [17.Rxd2 Be3 18.Kb1 Bxd2 19.Qxd2+/= ]
17...Qxb2? mutual blindness [>=17...Qb4+ 18.Kc1 Qxf4+ 19.Kb1 Qxg3-+ ]
18.Qc4+/- Qa3! a nice move, which I didn't see coming - the threat is .. Qe3#
19.Qb3 Qa5+ 20.c3 Qa6 21.Ne4 Rd8+ 22.Ke1?! I put a lot of thought into this move, although I'm not sure why [>=22.Kc1 Be3+ 23.Kb1 Rxd1+ 24.Rxd1+- ]
22...Rxd1++/= 23.Qxd1 necessary [23.Kxd1? Qd3+ 24.Nd2 Be3 25.Qc2 Qd5 26.Re1 Bxf4=/+ and it's going to be hard for White to get out of the bind]
23...Qc4?! [>=23...Be7+/= ]
24.Qe2+- [24.Nxc5?! Qxc3+ 25.Ke2 Qxc5+/= ]
24...Qd5 25.Rh3 Be7 26.Rd3 Qa5 27.Qd2 Qb6 28.Kf1 Nf8 29.g3 Qb1+ [29...Qc7 30.Nd6+ Bxd6 31.Rxd6+- ]
30.Kg2+- Nd7?? [>=30...Qb6+- ]
31.Rxd7 Qxe4+ 32.Kh2 Bc5 33.Rxf7 Qd5 34.Qxd5 cxd5 35.Rxg7 Be3 36.Re7 Bd2 37.Rxe6 Bxc3 38.Rd6 [>=38.Rxh6 also works 38...d4 39.Rf6 d3+- 40.h6 d2 41.h7 d1Q 42.h8Q+ Kc7 43.Qg7+ Kc8 44.Rf8+ Qd8 45.Rxd8+ Kxd8 46.Qxb7+- ]
38...Bb4 39.Rxd5 Kc7 40.e6 Kc6 41.Rd4 Be7 42.Kh3 a5 43.Rd7 Bf6 44.Rf7 Bc3 45.f5 b5 46.f6 Kd6 47.e7 Black resigned 1-0
