Without thinking about it too much... are you a bishop or a knight person?

[Roger de Coverly]

I've seen plenty of top players with white play into the Berlin endgame or play the Nimzo as black (which white seems to avoid at a high level) to get the impression that it all depends on the position.

A feature uniting such variations being inflicting doubled pawns on the opposition. Other lines with a similar theme would be the exchange Spanish including deferred versions, the Sicilian Rossolimo with Bb5xc6, the line of the Tromp that goes 1. d4 Bf6 2. Bg5 d5 3. Bxf6 and the similar idea used by Jobava that starts 1. b3 Nf6 2. Bb2 g6 3. Bxf6
