A bad decision since the white rook was far more active than its black counterpart. Besides, the pawn structure now becomes damaged.
1.a4! was a much stronger option, when Black should prefer Rd5 2.a5 Nd7 3.Rc7! Nxe5 4.fxe5 Rb5 5.Rxe7 with just a slight edge for White – Baburin.
Swapping the light-squared bishops in order to gain access to the c4 and c6 squares.
