With a double threat at e5 and a3.

Black is winning.

A strong tactical blow that eliminates White's bishop pair and leaves his pawn structure in ruins.

With double threats at f3 and a3.

An ideal square for the queen, where it eyes e5 and f2 at the same time.

6.Ra2 would be better.

Preparing ...Kg7 and ...Bxa3 with a decisive advantage.

Exploiting the fact that 1.Qd4! Nxh1? 2.Rg6! with mate, White secures a decent square for his rook.

Thanks to his extra pawn and active pieces, White is clearly better.
