White regains his pawn while keeping the dark-squared bishop as an important
trump. There is also 10...g5, when my slightly unusual plan involving Bf2 and
Na4-b6 works a treat. The next part of the chapter dealt with 9...Be7 10.Nf3
b5 11. Bxf6 gxf6, leading to a complex strategic battle. White's basic plan is
easy to understand: he just wants to play f4- f5xe6, then bring the c3-knight
to f 4 and improve his pieces while putting pressure on the e6-pawn. However,
we must pay close attention to what Black is doing, as one move might require
us to go about our plans in a slightly different way from the next. Pay close
attention to the Leko and Dolmatov games and you will get a good idea of how
to handle these positions.}) (16... h5) (16... Rc8) 17. Nd4 (17. b3 {ceeja:
