National Master

Machine-translated from the Portuguese article

Mestre Nacional (MN) is a title awarded by some national chess confederations, among them the Confederação Brasileira de Xadrez (CBX), to professional chess players who have obtained a rating of 2,200 points or higher on the FIDE or CBX rating list. The CBX received criticism after improperly awarding titles to some players, including players with a FIDE rating below 1600, which led one female chess player to renounce the Mestre Nacional title. In response to the criticism, the CBX created the titles of Mestre Nacional Online (MNO) and Candidato a Mestre Nacional (CMN), which distinguish titles earned in online games and those awarded by the CBX from the traditional ones.
