My guess is that he would initially be 1300, however with simple blitz practice he would become 1500-1700 or so.
What would Ruy Lopez de Segura rating be?

He was a match for the strongest players in XVI century Europe, namely the italians Paolo Boi and Giovanni da Cutri, he played in the first international chess tournament in Madrid 1575, he wrote a chess book in 1561, so he would be more than just 1300. I would say around 1800 playing slowly with an hourglass. Obviouly he would not play fast or blitz, that would be nosense at his time.

Yeah, you are right, I probably underestimated those patzers a little bit too much.
Reading trough his book he seems to have some deep touhhgts about the game, however I couldnt read too much about him.
Cutri crushed him tho. And he thought Nc6 was bad because of Bb5, lol.

I wonder why his opponent thought the Damiano defence was good...and took the knight. I expected them to be much better than that. I do not think they were comparable to what today is a 1800 rated player, more like 1500 (however, we do not have enough information). Anyways, we should not forget that chess had not been studied properly by then.
By the way, why do you always say Felipelandia?

Im ignorant when it comes to politics, yet I like to mock Felipe, your ruler.

Better mock Rajoy & Co. Felipe at least does his job properly (which basically consists of doing nothing)

Lopez read the book by Damiano. The book by Damiano (Pedro Damião) published in Italy in 1512 is not as basic as you think it is, you needed to be more than a 1400-1500 to write it and we may asume Paolo Boi was above Damiano and Lopéz in rating. So, if Damiano was a 1600, López could be a 1700 maybe and Paolo Boi, generaly considered the best player of the XVI century, would be like a 1800 or 1900.

Ruy red the book by Damiano, said it was trash and attempted to write another one.
I found the book, however I understand trash about it, Im also ignorant when it comes to languages so I dont know if that was supposed to be ancient Spanish , however he seems to talk in deepness, however I only understood 5 percent of it.

Rajoy me cae bien, su nombre me recuerda a un chile.

On sunny days his rating would be 2161
On cloudy days his rating would be 1952
Hehe, nice one.
I saw he knew basic tactics, he knew what a discovered attack was. (Bg4? - Bxf7+! - Ng5+ tricks)
He also knew what removing the defender was (he invented an opening based off on that, altough soon enough they discovered the fork and saw Bxc6-Nxe5.
He hung some pieces tho.
However he knew a lil bit about opening strategy.
There are no recorded endgames/middlegames tho.
What would his rating be, 1200? 900? 4607?
CHECK HIS PAGE SO YOU CAN INFORM YOURSELF BEFORE COMMENTING.
He was also probably smarter than most of you (but not more than me. Im humble) and didnt
waste his time on chess.com forums.

Seems like spaniards DO HAVE something to be proud about their country, if we can count the 1500s Spain as the 2016 FelipeLandia.
GRETTINGS DEAR FRIENDS.
