I like the idea of theme tournaments... I would like to play some Sicilian/Dragon/Youguslav... and some Caro-kan/Panov And even some "crazy" and not so usual lines... that would be good...
All I wanted was a chance to practice with humans some openings or setups. I took part in a theme tourney in another site, and I learned a lot about the opening, playing 10 games on both sides of the variation. It was great!
