Van Geet Opening?


Yes, 1. Nc3 is a transitional move. It transposes into Vienna Game, Queen's Pawn Game, Closed Scandinavian Defense etc. depending on pawn moves.

There is no main line. After 1.Nc3 black can play d5, e5, c5, f5, g6 ...
Most played is maybe 1.Nc3 d5 2.e4 dxe4 3. Nxe4
In Closed Scandinavian Defense 2...d4! is better for black than 2...dxe4.

Nc3 is known by a lot of names and is also called the Dunst opening or Queen Knight attack. It has a lot of analysis in a lot of different books. I like it for its tranpositional possibilities and because it makes your opponents stare at it in the most amusing manner when you play it. But you should be prepared for a lot of good replies! It is always fun to make the other person play YOUR game and hopefully get them out of their book.

I had some good success with it early on and then went to e4. I think I'll go back to it just for fun.

I have read the Keilhack book on 1.Nc3, It's wittily written and full of interesting ideas and analysis. Nice opening to mess around with, but ultimately I wasn't convinced.
Keilhack's book is not interesting if you want to study Van Geet's opening. It gives too much analysis but not the ideas after the moves. If you really want to study this opening you have to look after the book of Van Geet himself, "Van Geet Opening 1.Nc3", New In Chess, 1994. The main line is 1.Nc3 d5 2.e4 d4 3.Nce2 e5 4.Ng3. ( Yigor, this is not a transitional move ). Quote of Van Geet : " As there is nothing to fear from the black d-pawn anymore, White intends to play his bishop to c4, with prospects of a promising cooperation between this bishop and the g3 knight."
1...f5 doesn't make any sense after Nc3 because of 2.e4!
Right ! Van Geet's comments on f5 : " This move and 1 .. c5 have in common that they lack developing qualities, moreover 1 . .. f5 creates additional weaknesses and offers White more chances than after 1.d4 f5, since the move d4 can be omitted. " He gives following analysis :

Knight on the left by Harald keilhack was considered the bible of 1 Nc3 by 1 Nc3 players, but this book is 21 years old! The last book on 1 Nc3 came out in 2024, The modernized trojan Knight 1 Nc3, so it's the most recent on the subject.

Yes I think that 1 Nc3 f5? is a serious mistake because of the move 2 e4 which refutes Black's first move. The player leading the black pieces initially wishing to transpose into the Dutch defense (1 Ng3 f5 2 d4). I have only once encountered this line on the chessboard in the official game. This is the great difficulty of facing an unknown chess opening, the player tries to transpose into his favorite defense but here, it's a big mistake!
