Plans with g3 in the open games

What are the common plans for white in the 3.g3 Vienna game and in the Glek four Knights (4.g3)?

I don’t know about this “glek four knights” but from what I know about the Botvinnik structure in the English opening, whites basic idea is to fianchetto, play Nge2, d3, castles and f4.

Something like that, I guess.

That's interesting, thanks. 

g3 vienna is a tricky opening with a lot more venom than the black natural player may originally suspect.

 They are two main threats white aims for if black goes for the natural nf6 bc5, 0-0 nc6-d6 or c6 structure.

-White can often snatch the bishop via na4, giving white a long term advantage via bishop pair and no weakness. often this is why you see an early a6 thrown in for good measure

-white will aim for a kingside attack via h3- kh2 f4, often with f5-g4-g5 etc. often white can even afford a reroute of the queen knight via ne2-ng3.

The latter plan especially is Not easy to counter. IT's a lot like a King's indian where black doesnt have the queenside counterplay, and must instead rely almost entirely on breakthroughs in the center to dissipate the danger,but this is easier said than done, since white has his fair share of the center too.  early f5 often means no be6 to support the d5 break and a misplaced c6 only invites a timely d4!

Actually the biggest threat to the g3 vienna is probably. 1.e4 e5 2.nc3 nf6 3.g3 d5 which simplifies the game a lot more and the chance for a big kingside attack is almost entirely dissipated.

Dark is back!

Thank you, @darkunorthodox88. 

I added diagrams to the first post. 

I quit playing the Four Knights Glek after getting smashed by Joshua Freidel at the 2004 US Open.  I still have not figured out how to smash his unsound Gambit, but with g3 not played, it would be extremely easy.  I know there is an answer as otherwise everyone would be playing it as Black otherwise.

1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.g3 Nxe4? 5.Nxe4 d5 (0-1, 19)

@thrillerfan that looks suspiciously like a reversed halloween gambit

It pretty much is, the difference being in the Halloween Gambit, which is completely unsound, Black has g6 to go to with the Knight.  Here, White does not have the g3 square at his disposal.  His pawn is there.

Yes, when I've played this opening I've always given the piece back. Spoils Black's fun and you get the position you were playing for anyway.
