A dubious move that lets Black continue the plan he has in mind with extra tempi [A very good example for this variation is the game of Ponomariov vs Morozevich 8.Qe2 b5 9.g3 Bb7 10.Bg2 Bd5 11.c3 Nd7 12.b3 0-0 13.0-0 f5 14.Ned2 c5 15.c4 Bc6 16.Rad1 Rc8 17.d5 exd5 18.Qd3 bxc4 19.bxc4 Ba4 20.Rb1 dxc4 21.Qxf5 Rc6 22.Nxc4 Rf6 23.Qh5 Rg6 24.Rfe1 Bf6 25.Ne3 Bc3 26.Rec1 Bd4 27.Nf5 Qf6 28.N5xd4 cxd4 29.Qd5 Bc6 30.Qxd4 Bxf3 31.Qxd7 Bxg2 32.Kxg2 h5 33.Rb3 Qf4 34.Re3 h4 35.Rc6 hxg3 36.hxg3 Qh6 37.Rec3 Qh7 38.Rxg6+ fxg6 39.Rc7 Qxd7 40.Rxd7 Rf6 41.a4 Kf8 42.Ra7 Ke8 43.f4 g5 44.fxg5 Rg6 45.Kf3 Rxg5 46.Rxa6 Kf7 47.Rc6 Rd5 48.Rc4 Rd1 49.g4 Kf6 50.Ke4 Ke6 51.Rc6+ Kd7 52.Rc5 Kd6 53.Rb5 Kc6 54.Rf5 Kd6 55.a5 Ra1 56.Kf4 Ke6 57.Kg5 Ra4 58.a6 Ke7 59.Rf6 Rxg4+ 60.Kxg4 1-0, Ponomariov Ruslan 2684 - Morozevich Alexander 2742 , Moscow 2001 Ch World FIDE (KO-system)]

10...c5 11.c3
[11.c4 was interesting. But I didn't like that after 11...Qa5+ 12.Kf1 I would lose the right to castle. But maybe I should've tried it anyway]

[14.d5!? this sacrifice was a very interesting idea in order to open lines even at the price of a pawn 14...Bxd5 15.Bxf5 I also tried to find something interesting in other variations but didn't find something concrete although I have a feeling that there is something (15.Rd1 Nf6 (15...Nb6 16.0-0 Qc7 17.Bxf5 exf5 18.Nxf5 Rd8 19.Rfe1 Nc8 20.Ng5 Kf8 21.Qg4 with attack, here is an example of a possible variation 21...Bc5 22.Qh4 h6 23.Ne6+ fxe6 24.Qf6+ Kg8 25.Rxe6 winning) 16.0-0 0-0 17.Bxf5 exf5 18.Nxf5 Bd6 (18...Re8 19.Qe3 Bf8 (19...Kh8 20.Ne5 Bf8 21.Nxf7+ Bxf7 22.Rxd8 Raxd8 23.Qa7 ) 20.Qg5+ Kh8 21.Ne3 winning back the piece and getting a good position) 19.Qe3 Kh8 20.Qh6 Rg8 21.Rxd5 Nxd5 (21...Bxh2+ 22.Nxh2 Nxd5 23.Rd1 Rg6 24.Qd2 ) 22.Nxd6 Qf8 23.Qxf8 Raxf8 ; 15.0-0-0 Nf6 (15...Nb6? 16.Bxf5 exf5 17.Nxf5 Ra7 18.Rhe1 winning) 16.Bxf5 (16.Qe3 Ng4 ; 16.a3 ) 16...b4 (16...exf5 17.Nxf5 Kf8 18.Qe5 Rg8 19.Rhe1 Bc5 20.h4 h6 21.Qf4 Rh8 22.Re5 with attack) 17.cxb4 Rb8 18.Rhe1 Bxb4 19.Qe5 Bxe1 20.Nh5 (20.Rxd5 Nxd5 21.Qxh8+ Ke7 ) 20...Nxh5 21.Rxd5 Qxd5 22.Qxh8+ Ke7 23.Qxb8 Qxf5 24.Qa7+ Kf6 25.Nxe1 the position is about equal) 15...exf5 16.Nxf5 (16.0-0-0 Be6 17.Nd4 Qc7 18.Nxe6 fxe6 19.Qxe6 Nc5 20.Qxf5 Nd3+ 21.Rxd3 cxd3 22.Qh5+ Kd7 23.Qd5+ Bd6 24.Nf5 Qc6 ) 16...Nc5 17.0-0 Nd3 18.Rfe1 this is an amazing variation White sacrifices a rook and still have some compensation, Black is almost in zugzwang 18...Ra7 (18...Nxe1 19.Rxe1 Ra7 20.Qe3 Rc7 21.Qh6 Bxf3 22.Nd6+ Kd7 23.Nxf7 Qg8 24.Qe6+= ) 19.Qe3 Nxe1 20.Rxe1 Rc7 21.Qh6 Bxf3 22.Nd6+ Kd7 23.Nxf7 Qa8 24.Qe6+ Ke8 25.Nd6+ Kd8 26.Nf7+= ]
