The tournaments were sponsored by Louis D. Statham (1907–1983), a millionaire engineer and inventor. Hence, the formal title: the Louis D. Statham Masters.
Statham lived in Lone Pine and his many patents laid the groundwork for his company, Statham Instruments, which he founded in 1943.
His inventions ranged from instruments to measure strain and pressure in oil exploration to devices used to keep the country's space shots on course. For medical use, he developed a blood-flow meter, patient monitoring systems and catheter instruments that are placed in the heart.
Statham died after a long illness and his failing health forced the cancellation of the tournaments after the 1981 event.
The tournaments were seven- to ten-round Swiss system tournaments, with entrance requirements that made them the strongest in the country in the 1980s. Isaac Kashdan served as the tournament director.
Beginning is 1971 the winners were:
Larry Evans, Svetozar Gligoric, Arthur Bisguier, Walter Browne, Vladimir Liberzon, Tigran Petrosian. Then in 1977 the tournament was a between Yuri Balashov, Dragutin Sahovic, Oscar Panno and Nona Gaprindashvili. The following year Bent Larsen won and in 1979, Svetozar Gligoric, Florin Gheorghiu, Vladimir Liberzon and Vlastimil Hort tied for first. The 1980 was won by Roman Dzindzichashvili who was then playing for Israel. The final event in 1981 was won by Viktor Korchnoi.
The last game (Byrne-Stein) featured a position that had a material imbalance that lead to great complications. Here's another one from Lone Pine 1976.
For this sixth Statham Tournament, the rating requirements were slightly loosened, with the lower limit for adult USCF masters being dropped to 2300. A total 57 players participated, with an average rating of 2371.
The 1976 event was seven-rounds which at the time meant it was not a FIDE-ratable tournament, but the results were submitted anyway and the tournament rated after all. In the future, the tournaments were nine-rounders to meet FIDE rules regarding ratings and title norms.
Here are the leading scores:
In the following game the position after black's 19th move was very interesting because black sacrificed had the double exchange in order to get attacking chances against white's's King.
Silman wrote that during the game Petrosian showed great interest in the position, thinking black was doing well. After the game the two of them analyzed together and they played several blitz games from the position and Silman was able to demonstrate the superiority of his position much to Petrosian's amazement.
As expected, these days powerful engines like Stockfish and Komodo reveal hidden resources that change some of the evaluations, but that doesn't matter because Silman's instructions still have value because against humans they work.

interesting position. Stockfish gives white a +/- advantage. Silman explains
the position as follows. One advantage of having a material advantage is that
you can return it (or part of it) to quell as attack. Here black's position
has no weaknesses and with his next move Silman eliminates an important black
piece, creates a weakness in black's camp and goes on the attack. In a
Shootout white scored +2 -0 =3, so black does have some drawing chances.} 20.
