Unfortunately for Black, he cannot even save the b4-pawn.

With an easy win.

Inviting a queen exchange, after which the bishop pair would become even more significant.

1...Qe4? 2.e6! fxe6 3.Re1 with a strong attack.
1...Qf5 2.Re1 Nc7 3.Bb1 Qd7 4.Bd6 lets White keep the advantage.

In the absence of queens it becomes easier for White to advance his kingside majority.

With the double threat of 13 Bf6+ and 13 e7. White soon won.

To eliminate Black's bishop pair and take the game closer to the ending, in consideration of the favourable pawn structure.

1...Bd6? 2.Bxb6+-
1...Be7?! the knight is deprived of its destiny on e7.

White starts pushing his pawn majority.
