I have recently taken it up and works for me. I'm going to play in a tournament tonight and I'm thinking about playing it even if black doesn't play e5. I can still play it against openings such as the Sicilian. What do you guys think of g3?
I am a longtime KIA player from the 1. g3 or the 1. Nf3 move order, and occasionally from 1. e4 transposing, and I love to fianchetto on the kingside with both colors, but I am not a big fan of e4 and g3 together in the first two moves.
There is no opening that is fabulous against every conceivable defense, and combining e4 and g3 so early is very committal, and makes it easy for a good opponent to cherry-pick his response.
If I play 1. g3, I prefer to wait and let black play a few of his cards on the table, as I could later play c4, d4, e4, or even f4 to maximize my chances against whatever black shows me.
With the 1. e4 e5 2. g3 move order, usually black can play an early ...d5 and get a good game with easy development of his pieces.
GP's example is right on the money, and more importantly, it is thematic
- it is entirely reasonable to expect to see a typical club player play 2. ... d5 without thinking much about it.
Of course, it's also very possible that the typical 1. ... e5 player is going to see 2. g3 and think "I'm just going to play 2. ... Nf6 with a probable transposition to a Vienna, and if he plays anything else, I'm just going to see what white's avoiding 3. Nc3 will give me."
That said, if the idea appeals to you, play it and have fun. Win or lose, you will learn from the experience!
