[...] 1.d4 d5 2.c4 e6 3.♘f3 ♘f6 4.g3 dxc4 5.♗g2 a6 6.O-O ♘c6 7.e3 ♗d7 8.♕e2 b5 9.b3 I really like this pawn sacrifice. It creates very fast counterplay for white and pressure over the c-file and attacking chances 9...cxb3 10.axb3 ♗e7 (10...♗d6 is the other principal alternative) 11.♘c3 now Ne5 is the threat

11.♘e5 at once is not very promising since 11...♘d5 12.♗b2 ♘xe5 13.dxe5 O-O 14.♖d1 b4 15.♖xa6 ♖xa6 16.♕xa6 ♕b8 and black is fine

12...♘d5 13.♗d2 ♕b8 14.♘e1 ♘db4 15.♘e4 ♖d8 16.♖dc1⩲ white is doing a party on the c5 square

12.♘a4 ♘b8 opening the diagonal to develop the ligh squared bishop

12...O-O 13.♕c2 ♖b8

13...a5 14.♗b2 ♘d5 15.e4 ♘b6 16.d5 exd5 17.exd5 ♘xd5 18.♘g5 ♗xg5 19.♗xd5±

14.♗b2 h6 15.♖fd1± black can hardly move

13.♖d1 ♗c6 14.♗b2 ♕c8 15.♘c5 O-O although nothing special happened in the last few moves and black simply tried to develop, white has a very easy game and squeezes black. The key is not to exchange pieces in general, but the white squared bishop controls a lot of squares and removing it weakens black's
position 16.♘e5 ♗xg2 17.♔xg2 a5 18.♖dc1 ♗d6 (18...♗xc5 19.♖xc5 ♘bd7 20.♘xd7 ♕xd7 21.♖cxa5± will not help) 19.♕f3 ♘d5 20.e4 ♘b6 21.d5 trying to create theats now that black is not fully developed. 21...f6

21...exd5 22.exd5 ♘8d7?

22...f6 23.♘ed3 ♖f7 24.♘e6 a4 25.♗d4 axb3 26.♖xa8 ♘xa8 27.♘dc5⩲/ white has a lot of compensation for the pawn and probably enough time to create more threats

23.♘exd7 ♘xd7 24.♗xg7 ♗xc5 (24...♘xc5 25.♗f6+⁠−25...♖e8 26.♖c4) 25.♕g4 f5 26.♕g5 ♔f7 27.♗b2 (27.♗xf8 ♗xf8 28.♕xf5 ♘f6) 27...♗e7 28.♕h6 ♔e8 29.♖c6 ♖f7 30.♖e1 ♕d8 31.♗g7±/ white has a lot of compensation for the piece

22.♘ed3 e5 black tries to close the center and gain time to reorganize his pieces, but this does not work out well for him 23.♘e6 ♖f7 24.♕e3 ♕e8 25.f4 the logical reaction. All white's pieces are controling the board. The position is very hard to defend even in corr chess. 25...exf4 26.gxf4 (26.♘dxf4 a4 27.♗d4 a3 28.♖a2 ♘a6 29.♗xb6) 26...♕b5

28.♕f3 ♖xe6 29.dxe6 ♕xe6 30.♘c5 ♗xc5 31.♗xc5⩲ white will have some problems to covert to the full point.

28...a4 trying for counterplay 29.bxa4 ♘xa4 30.♘xb4

30.♖xc7 ♖xe6 31.dxe6 ♗xc7 32.exd7 ♕xd7 33.♘c5 ♕d6 34.♖xa4 ♕xh2 35.♔f1 ♕h1 36.♔e2 ♕g2 37.♕f2

37.♔d1 ♕f1 38.♕e1 ♕xe1 39.♔xe1 ♖xa4 40.♘xa4 h5 41.♘b2± could be winning but needs analysis

37...♖xa4 38.♕xg2 ♖a2 39.♔f3 ♖xg2 40.♔xg2 ♗b6 black probably holds

30...♗xb4 31.♖c4 ♖b8 32.♖xa4 ♗d6 33.♖c1 ♕h5 34.h3 ♘e5 35.♖a2⩲ white is better but black has still pulse

27.♘dc5

27.♔g1 ♘8d7 28.♘d4 ♕a6 29.♘f5± most moves are good in this position for white

27...♘8d7 28.♕d3 ♕xd3 29.♘xd3 ♘f8 30.♗d4 ♘xe6 31.dxe6 ♖ff8 (31...♖e7 32.f5 ♖ee8 33.♔f3 ♖ed8 34.♖a2±) 32.♔f3 ♖fd8 33.♔e3 ♔f8 34.♖c6 ♘c8

34...a4 35.♗xb6 cxb6 36.♖xa4 ♖xa4 37.bxa4 ♗c5 38.♘xc5 bxc5 39.♖xc5 ♖a8 40.a5 ♔e7 41.f5 ♔d6 42.♖d5 ♔c6 43.a6 ♖a7 44.♔d4+⁠−

35.f5 ♘a7 36.♖c4 ♘b5 37.♗c5 ♖dc8 38.♖g1 the black king is also a very weak piece 38...♖a6

38...♘a3 39.♖cc1 ♘b5 40.e5 fxe5 41.♘xe5 ♔g8

41...♔e7 42.♖xg7 ♔f6 43.♔e4!43...♔xg7 44.♖g1 ♔f6 45.♘d7 ♔e7 46.♖g7 ♔d8 47.f6 ♘c3 48.♔f5 and mate follows

42.♗xd6 cxd6 43.♖xc8 ♖xc8 44.f6 dxe5 45.♖xg7 ♔h8 46.♖d7 ♔g8 47.♔e4 ♘d4 48.♖g7 ♔h8 49.♖c7 ♖b8 50.♖b7 ♖c8 51.e7∓

39.h4 ♖c6 40.h5 the rest is as simple as just following the first move of the computer. 40...h6 41.♖g6 ♘c3 42.e5 fxe5 43.♘xe5 ♖xc5 44.♘d7 ♔g8 45.♘xc5 ♘d5 46.♔e4 ♘f6 47.♖xf6 gxf6 48.♘d7 ♔h8 49.♘xf6 a4 50.bxa4 b3 51.♖c1 ♖a8 52.♘d7 b2 53.♖b1 ♖xa4 54.♔d3In conclusion i really like how white can dominate on the board using the c5 square as the main center of operations and the expanding with e4-d5 (or e5) just squizing black.
