1.Nf3 I usually start 1.d4 but I decided to avoid any theoretical battle and play something that will surprise my opponent 1...d5 2.c4 e6 3.e3 c5 4.d4 In the end, we still end up in a d4 opening, the Tarrasch! 4...Nf6 5.Nc3 Nc6 [5...cxd4 6.exd4 Bb4 7.cxd5 Nxd5 8.Bd2 Is one of the mainlines, complex play arises] 6.a3 a6 Black prepares the a7 square for his bishop [6...Be7 7.dxc5 Bxc5 8.b4 Be7 9.Bb2+/= ] 7.cxd5 [7.dxc5!? Bxc5 8.b4 Ba7 9.Bb2 0-0 10.Qc2 Qe7 11.Rd1 Rd8 12.Be2 d4 13.exd4 Nxd4 14.Nxd4 Bxd4 15.0-0+/= White is better due to his advantage in development, as well as his advanced pawn majority on the queenside] 7...exd5 8.Be2 Ne4 [8...Bd6 9.dxc5 Bxc5 10.b4 Ba7 11.Bb2 0-0 12.0-0+/= ] 9.0-0 Be7 10.Qc2 Nxc3 11.Qxc3 [11.bxc3!? c4 12.e4+/= ] 11...c4 12.Ne5 Na5 13.e4 Be6 [13...f6!? 14.exd5 fxe5 15.dxe5 Qxd5 16.Bh5+ g6 17.Rd1 Qb5 18.Bf3 0-0 19.Bh6~~ ] 14.Bd2 Nb3 15.Rad1 Nxd2 16.Rxd2 Rc8 17.f4 If black manages to castle and finish his development, he will not have many problems. My idea is to overwhelm black's kingside and create a deadly attack on his king 17...f5? This move simply loses the game, it was crucial to accept the sacrifice and fight for his own counterplay afterwards [17...dxe4 18.d5 Bf5 19.d6 (19.g4 Bc5+ 20.Kg2 e3 21.Rd4 Bxd4 22.Qxd4 Bd7 23.Nxd7 Qxd7 (23...Kxd7 ) 24.Qxg7 Rf8 25.Qd4© ) 19...Bxd6 20.Nxc4 Bc5+ 21.Kh1 Qf6 22.Qxf6 gxf6 23.b4~~ ] 18.Bh5+ g6 19.Qh3! Bf6 [19...0-0 would not have saved the game but it would have been a more resilient defense 20.Nxg6 hxg6 21.Bxg6 Bh4 22.exf5 Bf7 23.g3+/- ] 20.exf5 1-0
