Answers.Text: Yes, the exact same thing is possible even with SCID. SCID vs PC is more user friendly and has a couple more features. SCIDvsPC works fine on WINE on Linux. I have tried this earlier.

  I have watched some matches played in the chess Olympiad in Tromsø. The majority of the games I watched, one player played the English opening, and usually he won, I haven't seen any French opening game.
  
  That makes me wonder if there's any site that has statistics about what is the most played opening, what opening has the highest winning rate and so and so forth.
