Well,ok my variation was of course not the best,because I tried to show the idea of what i am talking about.I think instead of Bc4 ,Nd2! will win very fast!Because this N will be transfered to e4 and the mate is near.But this move is only the best in this position!The most important thing ,which you should learn about this game is not to rush(Black will be worse all the time ,because he cannot castle anymore so you do not have to eliminate him immediately,you just have to put your peaces on their best squares in such types of positions!
