Aronian take the lead in game 4 by defeating Carlsen with white. In game 5 Carlsen will have the white piece and the position after 17 move look very promising to white (Carlsen). Aronian 16...Ba6 looks very attractive by attacking white queen at e2 after b4 and later exchange in c3 but I think it is rather slow compare to white kingside attack trough e5-Qe4-Ng5-h6 .

Now the game are tight with one game left. Aronian has the advantage of playing the white piece in the final game but surely Magnus will go all out. I think both player show the most interesting games and fighting spirit for the first round in Elista Candidate 2007!
