O-O d6 7. d4 exd4 8. cxd4 Bb6 9. d5 {Although this move closes the light squared bishops diagonal it has the advantage of disorganizing Black's game.} 9... Ne5 {9...Na5 10.Bb2 Nxc4 11.Qa4+ Bd7 12.Qxc4 would give White good play on the a1-h8 diagonal.} 10. Nxe5 dxe5 11. Bb2 Qe7 12. Bb5+ { 12.Qh5 Trying to win the e-pawn would fail after 12...Bd4} 12...
