Thanks to a slight material advantage and safer king, Black is better.

White keeps the d5-square under control, without worrying about the doubled c-pawns.

2...Qb7 seems more active, intending ...Rad8 and ...d6-d5.

From now on the ...d6-d5 break can be discarded, and Black is also suffering from a backward pawn on d6.

Having a firm grip on the centre, White starts an attack.

Preparing a consolidating f2-f3, as well as Rab1 with a fight for the b-file.

Too optimistic. 7...Re8 was correct, enabling ...Rb8.

Preparing Rb7 with a decisive advantage.

With focus on the enemy kingside. Now any capture on f3 will clear the g-file for the attack.
