With opposite-castled kings, Black opens up the b-file for his rook, and tries to obtain a strong square for his knight on d5 as well.

If White wants to keep control of d5 with 17.b3, his king’s position will be much more open after 17…bxc4 18.bxc4 ♖b8. The text move is not so useful either. Not only does it help Black’s development, but the exchange of the light-squared bishops also facilitates Black’s control of the d5-square.

White’s c-pawn is in trouble, while Black’s knight will be beautifully centralized on the untouchable d5-square. This rapid game saw some further adventures, and Black eventually won: …0-1 (63).

Reaching for the hook on h3! Black has not castled yet, and now he starts an attack on White’s king as quickly as possible, intending to open a file for the h8-rook.

17.♕f3 was about the only move to prevent …g5-g4, followed by …h4-h3. But after 17…♖g8, White can hardly stop …g5- g4 anyway.

Oops! Now, Black is completely winning.

If all the pieces were to be exchanged, the pawn ending would be winning for White. However, 20.♖xc8 ♖xc8 would clearly be a premature start, granting Black the only open file. Thus, Capablanca used the Karpov stratagem (again, an anachronism, of course!) to gain time for doubling his rooks on the c-file.
