My favorite defence is the petroff defence.
Here are a few openings I like.
The first one is Ruy Lopez and the secound one is the Queens Gambit Accept.
Also for Defense I like to respond with the Sicilian or the French .
I like to play the Scandinavian: Marshall Variation (I know you hate playing against it Phrostbyte, but it's the only way I can beat you XD).
