Chess Olympiad statistics

Question

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.

Answer 1

I don't know of any site that specifically does this for particular tournaments. But its very easy to do this yourself! Here's how you do it:

a) Download Scid vs Pc software (http://scidvspc.sourceforge.net/)

b) Download pgn for the Olympiad in Tromso 2014 from TWIC (http://www.theweekinchess.com/assets/files/pgn/olym14.pgn)

c) Open a new DB in SCID vs PC software and import this PGN.

d) Go to Tools > Opening Report

or

Windows > Tree Window

to get the opening tree and the percentages

Here's the output from Olympiad 2014 taken from Scid vs PC:
