Moreover, in this case the presence of the support point at f4 is a factor which strongly favours the Knights. The practical outcome of such a position is that White will have to look for a favourable moment to exchange one of his Bishops for a knight, bringing about a Bishop versus Knight struggle} 1... Nf7 2. Qf3 Rae8 (2... -- {White has the choice of three schemes: 1. He can exchange on Bishop at once (Bxf7) and then undertake the fight with good Bishop (3. Pf3!) against Knight 2. He can exchange the other Bishop for a Knight as soon as it appears on f4, but then he will have a Bad Bishop against Knight. 3. he can leave things as they are and keep both Bishops; but in this case he must work out some way of getting them into action. Scheme 1 is White's best choice} 3. Bxf7 Rxf7 4. dxe5 dxe5 5. Qf5+) 3. Qe3 b6 (3... -- 4. dxe5 dxe5 5. Qxa7) (3... exd4 4. cxd4 Nxe4 5. Qxe4+ Qxe4 6. Rxe4 Rxe4 7. Bd3 Rfe8 8. f3 $18) 4.
