Two Knights Defence: Kloss Gambit
edit5...Nb4!?
editA rarely seen gambit, named the Kloss Gambit. The point of 5...Nb4 is to attack the d5 pawn which is now is attacked twice and is only defended once. However, this move sacrifices a pawn for no clear compensation. This very crazy gambit can either lead to a bad position for black or sheer madness and craziness where sacrifices are everywhere and the moves are near unexplainable by an average chess player. Maybe a trick is involved in this interesting, unknown gambit?
6. c3 line
editWith white's sixth move c3, white attacks black's knight but leaves the pawn on d5 undefended and free to take.
These are some ways the game can go:
- 6...Nbxd5 7. d3 c6 8. O-O Bd6 9. Ne4 Bc7 10. Bg5 h6 11. Nxf6+ gxf6 12. Bh4
- 6... b5 7. Bxb5+ c6 8. dxc6 Nd3+ 9. Bxd3 Qxd3 10. Qf3 Bf5 11. a4 h6 12. Qxd3 Bxd3
- 6... h6 7. Nxf7 Kxf7 8. cxb4 Bxb4 9. O-O Bd6 10. d4 e4 11. f3 exf3 12. Qxf3 Rf8
6. d6 line
editWith white's sixth move d6, white renews the threat on f7 and moves away from the attack of the Nb4.
The game can continue with:
- 6...Nbd5 7. dxc7 Qxc7 8. Bb5+ Bd7 9. Bxd7+ Qxd7 10. O-O h6 11. Nf3 e4 12. Ne5 Qc7
- 6... Nfd5 7. d4 Qxd6 8. a3 Nc6 9. O-O Be6 10. Nxe6 fxe6 11. dxe5 Qd7 12. Qh5+ g6
- 6... Bg4 7. Bxf7+ Kd7 8. f3 h6 9. fxg4 hxg5 10. a3 Nc6 11. d3 cxd6 12. Bxg5 Qb6
6. O-O line
editWith white's sixth move O-O, white chooses to ignore the Nb4 and play normally.
There are a couple of ways the game can go:
- 6...h6 7. Nf3 e4 8. Re1 Be7 9. Ne5 O-O 10. Nc3 c6 11. dxc6 Qd4 12. Ng6 Bc5
- 6... Bg4 7. f3 Bh5 8. Re1 Be7 9. Rxe5 O-O 10. Nc3 Nd7 11. Ne6 Bxf3 12. gxf3 fxe6
- 6... Nbxd5 7. Re1 Be7 8. Rxe5 O-O 9. Nf3 h6 10. d4 c5 11. Bb3 Nb6 12. Na3 a5
6. d4 line
editWith white's sixth move d4, white chooses to attack the center and try to get a clear position without wild sacrifices flying everywhere. Will it end up to be a clear and typical gambit position or a crazy up and down unclear, extremely irregular position with minor piece sacrifices floating in the middle of the board like most of the other lines we saw? Let's find out!
The game can go like this:
- 6...Bd6 7. O-O O-O 8. dxe5 Bxe5 9. Nf3 Bg4 10. Be2 Bxf3 11. Bxf3 Nbxd5 12. g3 c6
- 6... exd4 7. O-O Nbxd5 8. Qxd4 Be7 9. Nc3 c6 10. Nxd5 cxd5 11. Bd3 O-O 12. Bf4 Bd7
- 6... Bg4 7. f3 Bf5 8. O-O h6 9. Nxf7 Kxf7 10. dxe5 Nfxd5 11. Nc3 c6 12. Ne4 a5
