I do agree with MNb about the naming of chess openings often being a random process.
I have my own "bȇtes noires" in this respect, e.g. some websites insist on calling the 4...Nd7 varuation of the Caro-Kann the "Steinitz variation", on the basis of no evidence that I can find.
Another one that annoys me is the "Bayonet Attack" in the Classical King's Indian; traditionally, a bayonet attack (in chess) was an attack by a single pawn (e.g. g2-g4-g5 in many open Sicilians), rather than part of the advance of a qualitative majority, as in the King's Indian, where there is little resemblance to a bayonet, as far as I can see. (I suspect an old Foxy video by Danny King might be to blame here).
Getting back to the Kalashnikov, I suggest there can be little doubt that the theoretical foundations of the modern handling of this line were indeed established by Sveshnikov, in his practice and his writings, e.g. in his brilliant article in New In Chess Yearbook 27 (1992).
But I think it's worth recognising that Sveshnikov himself, (like Fischer) a keen student of 19th century chess, was always scrupuluous to refer to 4...e5 as the La Bourdonnais variation.
MNb: 1) as far as I can ascertain, Bohak only once played 4...e5 5 Nb5 d6 and after 6 Nb1-c3 he immediately switched into B33 with 6...Nf6;
2) Pils sems to have only started playing 4...e5 5 Nb5 d6 in 1982; prior to that he had played one theoretically important game with 5...a6 6 Nd6+ Bxd6 7 Qxd6 Qf6, strategically-speaking a completely different concept.
There are other predecessors, of course, but I think it's very hard to argue that Sveshnikov does not deserve the greatest credit for constructing a whole opening system based on 4...e5 5 Nb5 d6.
Do we have a topic somewhere here on the naming of openings? I just came across another annoying one today; the Chessable course on the Ruy Lopez by Grandelius calls the line 3...a6 4 Ba4 Nf6 5 0-0 Be7 6 d3 the "Martinez variation". On what basis? Where the heck are these names being generated?!
6 d3 seems to have been first played by Kolisch in 1861, but I grew up knowing it as the Pilnik variation, since this Argentinean GM played it numerous times at the height of career in the 1950s (he even reached the Candidates in 1956). Chessbase has 27 of his games with 6 d3.
