Norwegian grandmaster Magnus Carlsen, the world's No. 1, won the championship in the rapid and blindfold quadrangular knockout tournament at the 2nd Grand Chess Festival at Mexico's National Autonomous University, or UNAM.

Carlsen downed the Hungarian Judith Polgar in the final in two three-minute games after the latter triumphed in the first game, a rapid-move 20-minute match, and the former tied it up in an eyes-covered confrontation.

In the first ultra-rapid, Carlsen played whites and forced Polgar out in the 40th move to go ahead 2-1.

In the second, the Norwegian moved blacks, dominated the board better and executed his moves masterfully to force the Hungarian to end the game in the 36th move for the final tally of 3-1.

In the duel for third place, Mexico's Luis Manuel Hoyos beat Lazaro Bruzon of Cuba.

After the final, UNAM rector Jose Narro Robles presided over the event's closing ceremony. EFE
