The Ruy Lopez is a very strategic opening, where White wants to build up the centre. The nature of the opening is that it puts pressure on e5. The bishop on b5 attacks the knight which defends e5. White would love to play d4, and if black is forced to play exd4 because e5 is impossible to defend, it would be lovely.
In the Italian game (3. Bc4) the game becomes very tactical, where sacrifices on f7 is quite common.
well likhit it seems Ruy lopez is better.
Ruy lopez's are extremly complex games, with a mind boggling amount of theory
