Not really.
The Zaitsev has a forced draw. The Marshall is a real lot of theory for a probable draw. The Berlin has little chance to play for a win. Most Chigorin lines are anything but active. In Play 1. e4 e5! Davies suggestes forced draws, in the In Keres lines with 12. exd4.
I would have to suggest something I have never played myself. The Modern Steinitz has active and interesting lines as well as safe lines. The Neo-Archangel is another option. The open Spanish is probably another option. But I never played these lines, so I don't really know.
So, as the title says, I'm attempting to choose a line to play against the Ruy Lopez. I'm preferably looking for an interesting and active line that (preferably) doesn't have any forced draws, and gives good chances to play for a win as Black. Any suggestions? (and if you know a good book for your suggested variation, please mention it :))
