Be2 Nf6 9. h3 {Preparing to drive back Black's knight, but weakening his king side.} 9... e6 10. f4 {White drives the knight from its good square, but his kingside is now quite porous.} 10... Nf7 11. dxe6 {If White had let Black take on d5 he would have had no compensation for the hole on e4, but now he falls behind in development.} 11... Bxe6 12. Bf3 O-O 13. O-O {White doesn't like the looks of 13 Bxb7 Nh5. Now, however, Black dissolves his only weakness and prepares to go to work on White's king position.} 13...
