In the first full book to examine 2.b3 against the Sicilian, French and Caro-Kann, mainlines, interesting sidelines and current theory are reviewed. In addition, what actually happens in modern practice is surveyed.
The authors are optimistic for White, and concentrate on the best continuations while trying to be objective. It is in that spirit that they conclude that 2.b3 is sound against the Sicilian, fun against the French, and curious against the Caro-Kann. In all three cases, the objective is to sabotage Black’s play, to take him out of his comfort zone.
