Roman recommends solid active lines. For lines against E4 Roman recommends d6, Nf6, and e5. With Roman's clear cut advice there is relatively little theory to remember. Against the Queens Gambit, Roman recommends the Nimzo-Indian Defense. Roman also gives you his best lines to meet The English, Tromposwki, and Knight f3. His lines are safe active positions to get you into a comfortable Middle Game.
