Chess Opening Theory/1. e4/1...e5/2. Nf3/2...Nc6/3. Bb5/3...a6/4. Ba4/4...Nf6/5. O-O/5...Nxe4/6. d4/6...b5

=Ruy Lopez: Open Defence=

7. Bb3 is necessary to save the bishop. From time to time some bright spark will wheel out 7. d5?! Easily dealt with, this can be.

Other Options

 * 7. Re1!?


 * 7. Nxe5!?, the Friess Attack.


 * 7. Qe2!?

These variations are not well-known and very dubious, but they might lead to fun positions.
