Buenos Aires Najdorf Memorial 1991
Julio Granda Zúñiga, Mikhail Tal, and Jesús Nogueiras shared first at the 1991 Buenos Aires Najdorf Memorial with 8½/13. The complete 14-player round robin contains all 91 games and three very different routes to the same winning score.
The second Najdorf memorial
Fourteen players met once each over 13 rounds. Alongside the three co-winners, the field included John Fedorowicz, Michael Adams, Sergey Dolmatov, Gilberto Milos, Oscar Panno, Bent Larsen, and leading South American masters.
That meant 91 games over 13 rounds.
A three-way tie, ordered by tie-break
Granda reached 8½ with seven wins, three draws, and three losses; Nogueiras scored five wins, seven draws, and one loss; Tal was undefeated with four wins and nine draws. Fedorowicz finished half a point behind on 8.
The contemporary Argentine chronology calls the finish a three-way tie and gives the tie-break order as Granda, Tal, Nogueiras. A wins-based table would name Granda alone, so the outcome must preserve all three co-winners.
