. Mission accomplished, with a clear positional advantage. There followed

and Black soon won.

Creating weaknesses on c5 and c6.

1...Qxc6 2.Qxc6 bxc6 3.Nc5 with a superior endgame, reminiscent of the encounter P.Benko-S.Reshevsky, US Championship, New York 1968.

White already has the better chances thanks to his strong knight and the sad bishop on c8.

A timely exchange that damages White's pawn structure and secures the f4-square for the knight.

Exploiting the mating threat in order to swap the active white queen as well.

Heading for b4 to intimidate the bishop and protect the c4-pawn.

The passed pawn has been neutralized, while the white rooks lack active prospects. Next Black may consider ...Rdb8 and ...Nd3 to put pressure on b2.
