Nc3 Nf6 (3... Be7 {Very interesting move. Ideas here is to prevent Bg5 immediately}) 4.

Nge2 {I like the Knight on e2 here instead of f3} Nbd7 9. Qc2 Re8 10. O-O {Just a line} Nf8 {[%cal Gf2f3,Ge3e4] Here we have the idea to pla f3 and e4} 11. f3 {Usually in this kind of structure White's plan is Rb1 and b4-b5 and starts a minority attack , but when you put the knight on e2 you have the idea of playing f3 which i prefer in this kind of position})) 4... c5 5. cxd5 Nxd5 6. e4 Nxc3 7. bxc3 cxd4 8. cxd4 {The Main move here for Black is Bb4+ but Black played ...Nc6 this gives White extra option, so what can White play here?} Nc6 9. a3 {Keeping the bishops on the board and that gives White advantage because White is trying to attack, he has the control of the center and with more pieces on the board it is easier to attack.

[#] Black is trying to play Ba6 exchanging the bishop and if he can manage to exchange this bishop and quickly put his rocks on C8 and d8 it will be extremely difficult to attack because Black is very solid here, no weakness in the king side, so without light square bishops White's attacking chances it will be very little, so White can't allow Ba6 so how he can prevent that?} 13.
