New idea in the Tajmanov B47
Theory develops more quickly these days because of the internet. An excellent example of this was round 5 of the King Salman Rapid where Magnus Carlsen played an idea in the Sicilian that had first been played just a week before in a Moscow tournament. As White won both games in impressive style, the theorists will no doubt already be working on a defence.
