Online Chess Tournament
I personally very like chess.com online base tournament. This help Chess Community grow rapidly compare tradition ways which cost alots.
Are they really practical? I still have amount of believe that face to face playing chess is much more ergonomic for eye viewing such as Tournament Staunton chess sets compare the Online Chess Tournament,(OTB) which is really good for people who want to practise skill or tactics in term of opening in chess.
They still a very fun way to play and hardly substitute tradition ways.
