Nd4 Kh8 {The strategic situation here is not unlike that of the previous example - two Bishops accompanied by a weakned pawn position. in what follows we shall see White working logically against eh pawn complex, while Black aims at opening lines. Remarkably enought, these plans do not cut across one another. black seems to play right into his opponent's hands; his pawns are badly doubled and isolated. Then, just when White seems to have realized his aims, suddenly it emerges that Black has also achieved his. The Bishops control the board and the resulting attack gives Black a decisive advantage.} 12. Kh1 Rg8 13. f4 Bd7 14. Bf3 Rc8 15. Nxc6 $2 { This strengthens the Black centre.} (15.
