Nf3 Nbd7 7. O-O e5 8. dxe5 {8.d5 Nc5 9.Qc2 a5 not allowing White to chase the knight away with pawn b4.} 8... dxe5 9. b3 c6 {Black has good chances due to the weak d4 square, which can be used as an outpost.} 10. Qc2 Re8 11. Ba3 { 11.Bb2 Keeping the bishop on to defend the d4 square seems more logical.} 11... Bf8 {The bishop no longer has a future on the a1-h8 diagonal so this exchange makes a lot of sense.} 12. Bxf8 Nxf8 13. c5 {13.h3 not allowing Black to play Bg4 and Bxf3 would keep better control of the d4 square.} 13... Bg4 14. Nd2 Ne6 {Headed toward d4!} 15. f3 {15.b4 Nd4 16.Qd1 would be better but still Black has the edge thanks to his strong knight on d4.} 15... Nd4 { With this move Black gets a strong outpost for his knight.} 16. Qd3 Be6 17. f4 {An oversight which costs White a piece. 17.Kh1 when White's king is safer tucked away in the corner.} 17...
