No more frustration to lose always to players much higher in ranks, without understanding why and without learning anything.\n\n2. No more boredom to win against players much lower in ranks, without satisfaction and without learning anything.\n\n3. No more endless tournaments where you forgot why you did the previous move and what objectives you had in mind.\n\nYou will enjoy tense and exciting games, open to any results, with satisfaction for achievements and learning from your mistakes.\n\nIf you do not believe me, ask players who played other Primus Inter Pares tournaments this year.",
