Three flaws -
1) 3.g2 is illegal, will assume you mean 3.g3
2) No opening exists without Black moves
3) Assuming #1, that already exists - it is nothing new. You didn't "invent" jack bleep!
1.Nf3 c5 2.c4 Nf6 3.g3 or 1.Nf3 c5 2.c4 g6 3.g3 or even 1.Nf3 c5 2.c4 Nc6 3.g3 are all lines of the Symmetrical English
1.Nf3 d5 2.c4 c6 3.g3 and 1.Nf3 d5 2.c4 e6 3.g3 are both very common lines in the Reti Opening.
The crown opening is an opening that I have newly created, it may be said that I am complacent and selfish, but in fact, I have created this opening with the help of these few years that I have been playing chess; Now my question is, do you like this opening ??
Moves :
1.Nf3
2.c4
3.g2
In a way, this opening is a combination of Reti and Indian King's attack, and I am happy that most of the time this opening is the winner of the game.
Please honestly comment on this opening I made.
