Van Geet Opening

has anyone good idea about Van Geet Opening Repertoire.
Also some good transpositions like
1. Veresov attack
2.Vienna game/Gambit
3. Jobava London

4.Chigorin

There is also the transition to Closed Scandinavian:

However, the most popular transition is to Closed Sicilian :

Just play 1.Nc3 followed by e4, and you’re golden. Of course there are alternatives like 2.d3, 2.Nf3, 2.g3, 2.d4, etc, but e4 is simplest.

Also French 1 Nc3 d5 2 e4 dxe4 3 Nxe4 e6
Caro-Kann 1 Nc3 d5 2 e4 dxe4 3 Nxe4 c6
Most critical 1 Nc3 d5 2 e4 d4

if you are only going to play 1.nc3 for transpositions, then you are better served with 1.nf3

the main purpose to play 1.nc3 is to explore unorthodox lines with independent value. This is  not to say that transposing to well known lines is a mistake however, and in fact, the best approach is likely a combination of independent lines and some transpositions.

Could U give an example of a good unorthodox line starting with 1. Nc3 ?

1.nc3 c5 2.nf3 intending for early d4 nxd4 but without  early e4
1.nc3 d5 2.e4 d4 (no scandi players, this is not your line, you dont have it copyrighted).
1.nc3 e5 2.nf3 nc6 3.d4 (no this is not a scotch, not having committed to e4 just yet makes a big difference).

Ok, thanks , it (with 1...c5/d5) could be called Mexican attack.

cf. https://www.chess.com/forum/view/chess-openings/mexican-attack-is-also-playable

not a fan. This is a mikenas defense a move up. But the problem is, in the mikenas, black ought to delay the development of the king knight because 1.it is good to have the queen diagonal unblocked in some lines and 2. they are plenty of lines where black shoudnt commit the king knight early, as sometimes, its best on f6 but sometimes, black ought to play f6 and nh6-f7. Your mexican attack already commits knight to f3 prematurely.

However, it's a variaton of the Closed Scandinavian (cf. my post #2 above). 😎

who you think gets priority as naming convention, a rare secondary line in an secondary opening or the main line of another opening.

This is the Van geet opening. Every opening of 1.nc3 acknowledges it as such.

All right, it sounds as a valid argument. 😎

Ok, this one is called Van Geet: Napoleon attack.

As you can see, this is no mere scotch! Lots of lines with plenty of traps and independent significance

With the Van Geet opening, I like to do a reversed King's Indian Attack:

It works pretty well, too.

Why should Black play 3...e6 or 3...c6 after 3.Nxe4?

Black has several good caro approaches (3...Bf5, 3...Nd7 and 3...Nf6) without bothering putting a pawn at c6.

It's rather opposite KIA = a variant of QIA. Reversed KIA = KID.

Right. 3...e5 is good too (and probably the most natural move here).

e5 is playable but very dangerous after bc4. ITs very easy for black to get knocked out quickly.

for example 4.bc4 nf6 5.ng5!
4.bc4  be7 5.qh5!
