Three Tied for Lead in Chess Play
Bent Larsen of Denmark, Lajos Portisch of Hungary and Boris Spassky of the U.S.S R. were tied for the lead with scores of 3½-2½ after six rounds of play in the Piatigorsky Cup International Chess Tournament at the Miramar Hotel in Santa Monica.
Larsen moved up by defeating Miguel Najdorf of Argentina in 69 moves in a game adjourned from the fifth round and completed Tuesday afternoon.
Starting the session a pawn ahead, but finding it difficult to make progress, Larsen returned the pawn to get his pieces free. The strategy was successful and a number of moves later Larsen won two knights for a rook.
It was Larsen's second win in succession, following his defeat of U.S. champion Bobby Fischer of Brooklyn.
Draw Game
An adjourned game from the sixth round was drawn in 43 moves between Portisch and Borislav Ivkov of Yugoslavia. Only one move was made in the second session, when the players agreed to split the point.
Also drawn was the game between Fischer and Wolfgang Unzicker of West Germany, which went to 78 moves. Fischer had a decided positional advantage when the session started, but could find nothing decisive.
The only remaining adjourned game was between Ivkov and Samuel Reshevsky of Spring Valley, N.Y., which will be played off Friday morning.
Reshevsky is the only player other than the leaders to have a plus score, 3-2. Fischer and Najdorf are tied with 3-3.
World chess champion Tigran Petrosian of the U.S.S.R., who has clearly not played in his best form, is tied with Unzicker and Jan Donner of Holland, with scores of 2½-3½. Ivkov has 2-3.
The seventh round will be contested at 6:30 p.m. today at the Miramar. The pairings are: Ivkov vs. Spassky, Donner vs. Portisch, Unzicker vs. Reshevsky, Larsen vs. Petrosian and Najdorf vs. Fischer.
Following are the details of two decisive games from the sixth round:
