particularly convincing. Much better is further quiet development, e.g.: } ( 8. b3 d6 9. Bb2 Re8 10. Be2 Ba7 11. Nxf6+ Qxf6 12. O-O Bf5 13. Bd3 Bxd3 14. Qxd3 Rad8 15. b4 Bb6 16.

A dubious decision and the germ of later
difficulties for white. That knight has no future on the king side. 13.Nc3
with idea Nd5 was preferable here. } ) 12... d6 13. Ng3 { A pure waiting move.
Black does not want to make any decisive moves before white has castled. Early
pawn moves on the king side could prove verydangerous indeed, should white
later decide to castle long. } 13... f5 14. Be2 Be6 { ?! Is risky and prematured, although white has to play precisely. } ( 14... h5 { with unclear game for black } 15. O-O h4 16. Nh1 g5 17. Rfe1 g4 18. Qd1 h3 19. g3 { ! The decisive moment in the game. At first glance the move looks bad
since it lets the knight out of its cage. In this concrete case it is much
more important, however, that the move prepares a dangerous black initiative
on the king side. The knight will soon have to go back anyway. Incidentally,
many continuations offer themselves here but, as often is the case, only one
leads to clear advantage. Let us look at a few alternatives: } ) 15. O-O f4 { white stays a little bit better, I think } ( 15... Rad8 16. Rae1 d5 17. cxd5 Rxd5 18.
