I just played a very short game in the Ruy Lopez, where I played white and pushed d4-d5 early, and it felt like I just gave black's knight a headstart to maneuvre into a better position where I was quickly lost. I thought that this push was common in Ruy Lopez positions so I was surprised this was so bad, and I can't find any master games in a similar position where this mistake is made (and it makes sense that I just helped black with their maneuvre), so why then is it so clearly bad here, but apparently thematic in other Ruy Lopez positions?
