Шахматная доска RUY LOPEZ, Exchanged Variation.

The Exchanged variation arises after 1.e4 e5 2. ¤f3 ¤c6 3. ¥b5 a6 4.¥xc6. It was a powerful weapon in the hands of Emanuel Lasker, but later on some reliable ways for Black have been found, and this line has acquired a reputation of being harmless and drawish. This estimation was refuted after several beautiful wins by Robert Fischer in the mid 60's. Though necessary improvements for Black have been discovered, some modern grandmasters (Timman, Rozentalis, Glek, Yandemirov) play it with White successfully.
Шахматная доска Variation with 5. d4.
To counterbalance the opponent's kingside pawn majority, Black has to actively utilize his bishop pair. A good example showing how passive play leads Black to trouble is 1st game of the World championship match between Lasker and Tarrasch.
[...] 1.e4 e5 2.¤f3 ¤c6 3.¥b5 a6 4.¥xc6 dxc6 5.d4
An old-fashioned move. Fischer preferred 5. 0-0; today 5. ¤c3 is also sometimes played.

The Tarrasch's move is also good, because a piece attack on the e4-pawn in combination with a timed f7-f5 thrust will activate the black bishop pair thus giving him good chances.)
10.f3 ¥e7 11.¥b2 ¥f6?
Why give up a bishop pair? Better is 11... ¤f6 followed by 12... 0-0-0.

White's advantage is increased with every exchange. More reliable is 19... ¥b7.

Lasker's plan consists of the following steps:
1) to blockade the black queenside pawn chain;
2) if possible, to cut off the black king by the d-file;
3) to transfer the white king to the kingside;
4) to advance the kingside pawns.

Шахматная доска In the following classical game Black managed to conduct a plan of occupying the d-file.
[...] 9.¤bc3
This is better than 9. b3, because White avoids weakening of his queenside pawns.

9...O-O-O 10.¥f4 ¥c6
Black combines play along the d-file with pressure on the e4-pawn. He intends to conduct f7-f5, when e4-e5 in response will be impossible.

Шахматная доска Lasker's Invention: f4-f5!

Emanuel Lasker was an adherent of the Exchanged variation and in his games vs. Capablanca and Janowski he introduced an innovative method of fighting for the initiative.
[...] 1.e4 e5 2.¤f3 ¤c6 3.¥b5 a6 4.¥xc6 dxc6 5.d4 exd4 6.£xd4 £xd4 7.¤xd4 ¥d6 8.¤c3 ¤e7 9.O-O O-O 10.f4
Capablanca considered this move weak because it weakens the e4-pawn and gives Black an opportunity of ¥c5.

10...¦e8 11.¤b3 f6 12.f5
This is the Lasker's invention. The e4-pawn becomes backward, but White widens the scope of the c1-bishop and creates an outpost on e6.
