To add to that we have:

39. Sicilian Chameleon System (1. e4 c5 2. Nc3 3. Ne2)

40. Sicilian Pelikan (1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Nb5 d6 7. Bg5 Be6)

and this gives us a nice even number.

You are still only at 39.

Pelikan and Sveshnikov are the same thing. Kinda like the Taimanov and the Paulsen - same thing.

Ah I figured out why. You're correct, the Pelikan and Sveshnikov are essentially the same. What I meant was the Bird Variation which is, from the Pelikan, 7. ...a6 8. Na3 Be6, while the Sveshnikov is 7. ...a6 8. Na3 b5.

I believe this to be quite inaccurate information. Spellings and moves alike.

For a bit more info, please read GM B. Smith's informative article on the Paulsen Sicilian: https://www.chess.com/article/view/the-history-of-the-sicilian-paulsen.

The Paulsen is just another name for the Kan. The Taimanov is simply 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6, while the Kan (aka Paulsen) has as its fourth move for black 4...a6 (instead of the 4...Nc6 of the Taimanov).
This can be confirmed from a variety of sources: Chess.com article by GM Bryan Smith, the book Modern Chess Openings (13th Edition), Wikipedia, chess databases online, etc...

38. Prins Variation (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.f3!)

I think No. 24, the deferred wing gambit is incorrect; I believe it should be:

1. e4 c5 2. Nf3 d6 3. b4.

I'm not sure what the listing is above, but 1. e4 c5 2. a3 is called the Mengarini Variation.

Nope, 24 is right. The main line runs:

1.e4 c5 2.a3 Nc6 3.b4 cxb4 4.axb4 Nxb4 5.d4 d5 6.c3 Nc6 7.exd5 Qxd5 8.Na3

Here's the best one:

Here, Black basically has 2 decent options, and the rest almost lose by force! My preference as Black would be 8...Bf5 if I had to deal with this position.

Another cute line (I used to play this as White) is 1.e4 c5 2.a3 e6 3.b4 cxb4 4.axb4 Bxb4 5.Ra3! Bxa3 6.Bxa3 and Black has major dark square issues.

There is an entire 550+ page book on this from a little more than 2 years ago.

SO how the hell does anybody play that opening and keep track of all that?

Well, I suppose it's a bit like local geography. You will know the streets round by where you live very well . The streets in your town generally quite good. Your county well and so on. Certain other places where you go on holiday and to work etc etc You don't need to know the whole street plans - just the ones you walk around. Even in a new town you will have a general idea where things are and you can ask people and so on...Of course just like chess variations you don't have to remember street names except when giving others directions !
