1. d4 d6 2. e4 Nf6 3. Nc3 g6 4. f4 Bg7 5. Nf3 c5 6. e5 Ng4? Mixing up l ines! Nfd7 has to be played heere. After Ng4, dc5 gives white a big advantage 7. h3? cxd4 8. Qxd4 Nh6 9. g4 Nc6 10. Bb5 O-O 11.

Nd7 Bf4! and white is well advised to take the perpetual check) 28... Rxc2 29. Rd1 Bd2 30. Ke2 Bg5+ 31. Kf3 Bxf6 is surely not losing for black 1/2-1/2
