The new format has proved to be attractive and successful.\n\nThe previous edition of the round robin took shorter than any other tournament I participate in: from February till May. It will give you a quick but meaningful assessment of your potential\n\nThe best chance to focus and to enjoy a challenging tournament, free of frustration, pure pleasure. \n\nJoin as soon as you can to make sure that you are still 12 k.",
