📕 17...Qe6!
Not only breaking the pin on f7 and so clearing the way for ... f7-f5, but also challenging the white queen. Naturally, Capablanca has no wish to play 18...Qxd5? when 19 cxd5 strengthens the white pawns and opens the way for an attack on c7 by Rac1 etc. No, Capablanca is preparing to exchange queens on his own terms.

📕 18.a6!!
We are all taught not to move pawns on the side of the board where we are being attacked, lest they provide a hook for the opponent's pawn storm. However, Petrosian's crafty little pawn move completes the blocking strategy that began with 17...c4. If 19 a5 Black replies 19...b5!; or 19 b5 a5! and the pawns become interlocked, forming an invincible barrier to a white attack.
