12.Bc1 The most logical plan. An idea could be Ba3, Be2, 0-0, Nd2 and Nb3 what secures white some advantage. 12...Nc5 13.Qc3 f6 14.Be2 b5 An dynamic idea from Rybka. It seems that it is not good to open the position for the two bishops, but the in the center pladed Knights will be strong too.

Three pawns and atack for teh piece, Qe4 could already win here

I am sorry that i had not looked enough for usefull candidatemoves of my opponent. Also if Rd4 si not strong I should have had a look on it before playing e4. [25.Nh3 Nd3 26.Nf4 Nge5-+]
