I’m back home after commentating on the London Chess Classic last Friday, but I’m due to return next weekend. One interesting thing happened meanwhile in that my son, having seen me commentating, became interested in following the games. Prior to this he had been looking at the games of his peers, which provided far from optimal models of play.
You can learn a lot from following tournaments online, especially if you try to guess the move before it is played (active involvement). Of course not everybody finds the Berlin (1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6) fascinating, and this suggests that perhaps with need tournaments with mixed strength participation. But even so it can be useful.
Here anyway is the Youtube video of round 1.
