(a) Now Black must decide which pawns he wants to take.
(b) Exchanging Queens here gives White the advantage of a pawn plus better center possibilities.
(c) 13. … QxBP4 was best here.
(d) Petrosian is now playing powerful chess. Black hardly dares castle either side and the onward march of the center pawns makes things look tough for Black, who puts up a gallant fight.
