Sources on the Open Ruy Lopez


Thanks for the answer. So you never used a theoretical source?
BTW, what is your answer against 6.Re1? This should be unambitious but it's seen very often in blitz. If i remember correctly the 2 accepted reactions are 6...Nc5 and 6...b5, right?

thanks to everyone for the answers! Sorry for the lack of feedback but i was without an internet access during the weekend.
Regarding the 6.Re1 variation i have come across some nicely annotated games showing 6...Nc5 as the best variation, as both offtherook and paulgottlieb said.
I will give a look to the suggested book!
Thanks to everyone!
