C04: French Tarrasch: 3...Nc6
1.e4 e6 2.d4 d5 3.Nd2 Nc6 4.Ngf3 Nf6 5.e5 Nd7 6.c3 f6 7.exf6 Qxf6 8.Be2 Bd6 9.0-0 [9.Nf1 0-0 10.Ne3 Qg6 11.0-0 Nf6 12.c4 b6 13.a3 Bb7 14.b4 dxc4 15.Bxc4 Rae8 16.Bb2 Ng4 17.Bd3= Sebag-Brynell, Malmo Masters 2003]
9...0-0 10.Nb3 h6 11.Be3 e5?! [11...b6= ]
12.dxe5+/= Ndxe5 13.Qxd5+ [interestingly in Ursic-Hoolt, World Junior Girls 2005 (two 2000+ players), Black chose instead 13.Bd4?-/+ ]
13...Be6 Black gets some minor activity from this sacrifice, but I don't think it is enough
14.Qe4 Rad8?! [14...Nxf3+ 15.Bxf3 Rae8+/= ]
15.Nxe5 Bxe5 [15...Qxe5 16.Qxe5 Nxe5 17.Rfe1+/- ]
16.Nc5+- any compensation has already dissapeared
16...Bd5 [16...Bf5 17.Qc4+ Kh8 18.f4+- ]
17.Bc4! Qf7 18.Bxd5 Rxd5 19.Rad1? this move should have blown the game [19.f4 Bd6 20.Nxb7 Re8 21.Qf3+- ]
19...Rfd8? [>=19...Bxh2+! gives Black the edge 20.Kxh2 (20.Kh1? Rh5-+ wins at least a piece) 20...Rxd1 21.Rxd1 Qh5+ 22.Kg3 Qxd1 23.Nxb7 Rf6=/+ ]
20.Rxd5+- Rxd5? Black had to trade queens here [20...Qxd5 21.Qxd5+ Rxd5 22.f4+- (the point of the queen trade was now Black's rook indirectly protects his b-pawn 22.Nxb7? Rb5= ) ]
21.Qg4 [21.Nxb7 Na5 (note that 21...Rb5? doesn't work with the queens on the board 22.Qxc6+- ) 22.f4 Bd4 23.Bxd4 Nxb7+- ]
21...Rd6? [21...b6 22.Ne4+- ]
22.a3?! I'm not sure what my resistance to capturing on b7 was [>=22.Nxb7 might be the shorter path 22...Rf6 23.Qa4+- ]
22...b6+/- 23.Ne4 Rg6 [23...Qe6 24.h3 Qxg4 25.hxg4+- ]
24.Qe2 [24.Qc8+ Kh7+- ]
24...Ne7 25.f4 Bd6 26.Nxd6 Rxd6 27.Bd4 Nf5 28.Be5 Rd7 29.Qe4 [29.b4 Qd5+- ]
29...c5 30.Qe2 Qg6 31.b4 cxb4 32.axb4 Nd6? [32...b5+/- ]
33.Rd1 [33.Qd2 Rd8 34.f5 Qg5 35.Qa2+ Kh7+- ]
33...Qe6?? now White can just win a piece [33...Re7+- ]
34.Qd3 Black resigned 1-0
