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.

The only chance for counterplay.

With threats on both flanks, White is clearly better.

By exploiting the potential pin along the d-file, Black damages the enemy pawn structure.
