The Center Game

try to play e4 e5 Nf3

Is the novelty 4.Qxd4! yours, or you have seen it somewhere?

The only trouble with the 8.Qg3 line is that it was refuted some ten years ago by Paco Vallejo.

I think StupidGM meant 1.e4 e5 2.Nf3 Nf6 3.d4 exd4 4.Qxd4 although you generally see 3...e5 more often. But yeah.. it's usable this way against more than Nc6 by black. 

Although I would never play this opening ever

Nice opening if you want an unbalanced (opposite castles almost always), tactical (open center) non-theoretical game. Be careful with your queen!!

That is actually a work of art

I used to play it for some years, after reading chapters written by Andrew Geet in Dangerous Weapons 1.e4 e5. And I had great results.

But unfortunately, as pfren said, the entire Qg3 line is refuted.

The line is this one :

Nowadays, some GM tried a new idea :

It can be useful not being on e file, sometimes playing for Bg5... Food for thought...

e4 e5 d4 if black plays the horrible f6 dxe5 fxe5 Qh5+ If g6 Qxe5+ wins a rook so black should move the king right? No! It’s mate. Ke7 Qxe5+ Kf7 Bc4+ d5 Bxd5+ Now Qxd5 is best else mate Kg6 Qg3+ If Kf6 Qg5# so Kh5 Bf7+ g6 Qf3+ Bg4 Qxg4+! Kxg4 h3+ Kh4 Nf3+ Kh5 g4# (or Kh5 g4+ Kh4 Nf3#)

my coach taught me that and it has won me a few games

Eventually, you'll end up in a game with someone who won't fall for all this nonsense. Then what do you do?

actually I said it won me a few games, not all of them. I just think it is a nice mate and wanted to share it with you. number 2, after fxe5 black has to play d5 and qxd5 to avoid mate. then regardless of that player's skill, he is in a mating net that he cannot escape. so if he doesn't play f6 I just play normally,

That kind of reminds me of a goofy friend of mine who tries to play against the Evans Gambit like you do the Giuoco Piano (with an early d5) even though he's two tempi down. He's been doing this for over a decade. I tell him to look up the line and figure how to play it properly. He doesn't, so I keep beating him in exactly the same way. I can't depend on anyone else playing like this though.

instead of taking with queen why not use danish to attack fast?

I'm not fond of the Center Game, because I find that it leads to Black chasing White's queen around the board. I did just that a minute or two ago, and I made my opponent resign after 8 moves. I'm Black.

and youre playing people on the begginer side so opening theory is irrelevant basically

The Q usually retreats to e3

exactly or d3
