With the double threat of 4 Rxd4 and 4 Re4.

With the decisive threat of 7 Re8+. White won just a few moves later.

Trying to exchange, or at least dislodge the active black rook.

Or 1...Rxc1 2.Rxc1 Bd6 3.Na4! , heading for c5 or b6, when 3...Bxf4? fails to 4.Qxf4.

White just sends his passed pawns forward with a clear advantage.

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.

Forcing the exchange of White's more active minor piece.

With ideas like ...Nd3 and ...Kf7-e6-d5. Black soon won.
