Benko Opening
1.g3!?
Sort:
It's the benko opening.
It usually transposes to a king's indian attack or a reti.
I like it. It was my #2 otb opening for some time, when not in an e4 mood. Being a Kings Indian player as black helps a lot with it, both being hypermodern. More flexible than Nf3. You could find games with 1.g3 from CCM Stephen Gerzadowicz who played it for years, did a lot to develop it into a system, even beyond 15 or 20 moves deep. He wrote about it in APCT. And probably played it in the USCCC or Absolute postal championships he was in. As far as books on it, I havent read any nor seen any, but then I havent looked. Being so highly flexible as it is, I've always thought someone playing it was looking for something less usual and to pave their own way in it. Still, having reference games at least, would be nice.
Around here we've always called it "g3" 
. Not much help eh? Well why not go with it if you enjoy it, and you can name it, or we can name it for you someday :)) Regards, CraigAC
PS I have a bit of trouble thinking of it as a Benko. Since adding Nf3 and c4 to it, can easily become a Benko Gambit Defense Reversed. Then do we have to say , "the game was a Benko Reversed Benko" ?! Which btw can be a very killer opening to get as WT if black were to try to play it the way WT plays vs a Benko Gambit, but colors reversed. Anyway, sounds like there should be Pal Benko games to look at too then. Quite a good player. Qualified for the Interzonals you know, for the WCC, then ceded HIS spot to Fischer that year at the request of USCF ( or someone )... since Benko may be a pal, but was not Bobby's (after a 'near' fisticuff discussion of a game they played, it is said) .And the rest is history, ala Spassky vs Fischer 1972. And thinking over that, guess I will call it the Benko too from now on. If not for Pal the USA would have missed a "Golden Age" of chess popularization here. He did a lot for Chess. RJF helped a bit too of course. 
thx guys
A little update I stumbled across just tonight in the book "The World Chess Championship; A History" by Al Horowitz ...and enjoyable book btw. It tells more of the g3 & Benko matters. Putting into my own words it basically tells that:
The Benko-Fischer game was notable for Benko opening 1.g3 there, and later using it in the tournament to defeat Tal (!). These led to it coming to be called the "Benko System". The Fischer game led to the "altercation" between those two, who went without speaking to one another the rest of the event, creating a delicate situation for GM Arthur Bisguier who was there to act as 'second' to both Americans.
I've been this move alot lately by myself, without resources, for the simple reason that I can't find one. First of all, can anyone tell me what this opening is called? Chess.com game explorer says it's Hungarian Opening, while Wikipedia says that the Hungarian Opening is 1.e4 e5 2.Nf3 Nc6 3.Be2. And, secondly, may I ask for everyone's opinion on this move?
