Fischer complained about it sometimes. The soviets do even worse: start to comment his game near him when he's playing another soviet player.
Okay, the Soviet State tried to influence as much as it can the results in chess, but it would be impossible to the soviets to dominate chess without good players. My favorites so far was Petrosian and Tal.
Besides, i read here once that Benko had to give up his place in the candidates tournament so Fischer would have a chance in the world title. I don't know if that really happened, but if it did, I suppose a professional chess player would never gave up a chance to the world title unless someone convincing him. And I guess U.S government did this.
Another influence(I suppose again) was Caruana recently going to the USCF, out of the blue.
I'm just putting another point of view in this discussion.
Specially that time, U.S and the Soviets governments would try anything to prove its supremacy.

To date, there have been no files found in the archives of the KGB (estab. 1954), or its predecessors in Soviet state security, the MVD and the MGB. Therefore, much of the events of 1946 to 1948, within the Soviet camp, comes from hearsay and deduction.
We saw in Part 2 the masterful manueuvering of the Soviet chess authorities into creating the most favorable conditions for putting a Soviet in the World Champion's seat. They had finagled a majority of the players in the match-tournament and managed to get three out of five stages played in Moscow.
Of the two non-Soviets, Max Euwe was the former World Champion and Sam Reshevsky was the several times American champion. They were considered two of the top three or four "Western" players (along with Najdorf and Fine). The concern was that the Soviets were going to manipulate game results among themselves, rather than as individuals, fighting for the title.
"Briefly, the suspicion was that the Soviet players in these tournaments played 'as a team.' This could take two forms: (1) the weaker or less politically favored Soviet players could deliberately lose their games to the more favored one ... or else, (2) the Soviet players could agree to a series of short draws among themselves, preserving their energy for games with the western players."
As Botvinnik was the premier Soviet player (and a favorite of Stalin), and Smyslov was the up-and-coming young Russian, suspicion focused on Keres, who had been under a cloud since his wartime chess activities with the Nazi regime during World War II.
This was true even before the competition started. The Soviet contingent that travelled to the Hague for the first two stages contained a number of chess experts to aid their three players, as well as several apparatchiks and members of State Security.
Each stage of the match-tournament contained ten games played in five rounds. Each player had a bye once each round. The true standing were known at the end of each stage.
In the first stage, Keres played Botvinnik in Round 5. At the time of the game the players stood: Botvinnik (2.5), Keres (2) Smyslov (2-bye), Reshevsky (1.5), Euwe (0). In each stage, when Botvinnik was to play Keres, Reshevsky was to play Euwe.
It was clear Euwe was bady out of form. Botvinnik had prevailed over Reshevsky in Round Four of stage one, when Reshevsky blundered away a win in time trouble - a close call for Botvinnik, otherwise Reshevsky would have been in the lead.
Here is the Keres-Botvinnik game: http://www.chessgames.com/perl/chessgame?gid=1032181

Keres had White and played the English opening. Keres unwisely trades a Bishop for Botvinnik's badly placed Knight on h6 (move 18), then errs on moves 32 and 38, leaving himself with the worst of it. However, at several points in the game, Botvinnik missed the strongest continuations, such as his tit-for-tat error on move 38.
At this point, Keres could have locked up the pawn structure in front of Black's King, and transferred his rook over to the defense of his own king. Instead, he depleted the pieces around his king and opened attacking lanes for Botvinnik.
After the adjournment Keres's position deteriorates with continued weak play. Win for Botvinnik.
They meet next in Round 10 in stage 2. At the time, the standings were" Botvinnik (5), Keres (4), Reshevsky (4), Smyslov (4-bye), Euwe (1). If Reshevsky were to beat the hapless Euwe, he would catch Botvinnik with a Keres win.
Botvinnik stated the Keres appeared for the game shaken and nervous. He attributes it, oddly, to Keres not having had to play for several days. (Botninnik included this game in a book, "15 Games and Their Stories", English translation 1982.) He writes: "I Told them [Keres and Smyslov], most sincerely ... 'One of you will get six days of rest and lose like a child on the seventh day.' Now the first part of my prophesy had been fulfilled. After six days rest, Keres sat across from me, pale as death." Perhaps a more convincing explanation might have been that Keres had been "visited" by State Security before the game.
Here are the moves:
1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3 O-O 5.a3 Bxc3 6.bc3 Re8 7.Ne2 e5 8.Ng3 d6 9.Be2 Nbd7 10.O-O c5 11.f3 cd4 12.cd4 Nb6 13.Bb2 ed4 14.e4 Be6 15.Rc1 Re7 16.Qxd4 Qc7 17.c5 dc5 18.Rxc5 Qf4 19.Bc1 Qb8 20.Rg5 Nbd7 21.Rxg7 Kxg7 22.Nh5 Kg6 23.Qe3 1-0
In any case, Keres played an exceedly weak game. In 1938, Keres had played the Nimzo-Indian against Botvinnik and won the game, by hemming in Botvinnik's bishop pair. He would do that again in 1951 to Botvinnik and win. But in 1948, Keres throws theory out the window, with uncharacteristic mistakes on moves 11 to 13 and 16.
Perhaps this was just a bad game for Keres. A good YouTube analysis can be found here: https://www.youtube.com/watch?v=tNrFNXiXcGc]
As the YouTube presenter states, "The moves looked a bit dodgy!" Botvinnik does finish off Keres in nice fashion however.
