In this week's lesson, Dennis continues his series, the Quick Ruy Lopez, with an analysis of black's sidelines after 4.Ba4. He studies the Norwegian variation (4...b5 5.Bb3 Na5), the Delayed Schliemann/Jaenisch (4...f5), and the Steinitz Deferred (4...d6). This is a good wrap up for white players looking to fend off pesky sidelines and black players who want to mix things up. Dennis covers a wide variety of ideas for both colors, but don't worry, he keeps it straightforward and easy to follow. Enjoy!
