Preferable was 8.Qd5 Qxd5 9.exd5 with just a slight disadvantage – Cebalo. In the game Black achieves a strong rook manoeuvre.
Intending 2...Bxc3 and 3...Bb5 with favourable exchanges, after which the knight can be installed on e4, where it will clearly outshine the remaining white bishop.
. Mission accomplished, with a clear positional advantage. There followed
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.
