I played three games and lost them all. It's as you said, I felt that in the opening they knew something I didn't and they entered quickly in my camp. The strange thing is that when I played last year, I didn't have that feeling at all, the games felt pretty even - I won one game because my opponent resigned after I declined his draw offer.
If you want we can play some games some day. My email is in my profile if you're interested.
