Yes, I actually play 1. d3 myself sometimes to get into a King's Indian Attack formation against most anything black will play.
1. d3
Chao, I suppose that you mean 2. .... - Bb7. But why makes it your Bishop weak? You often see the fiancetto....

I'm about half way through writing a book on 1.d3 ( 1.d3 The Little Big Opening) White has many plans and can find himself in a reversed Philidor - Hanham Variation, a reversed Sicilian, a reversed Benoni or K.I.A. or a reversed French / Caro Kann.
It is difficult for Black to find a bad move against 1.d3 but 1...d5 is probably best followed by 1...e5.
White is conceding the centre, so why not take it? But it does play into White's hand.
The opening is, therefore, very flexible and can be arrived at via 1.Nf3, 1.e4 1.c3 1.a3 (Anderssen's Opening).
Here is but one line, not forced of course:
1.d3 d5 (1...e5 allows 2.e4) 2.a3 e5 3.c4 dxc4- The Exchange Variation (The Bumblebee), continues - 4.Qa4+ Nc6 5.Qxc4 Be6 6.Qa4 Nf6 7.e3 Bd6 8.Nd2 0-0 9.Ngf3 Qd7 10.Be2 a6 11.0-0 Rfe8 12.Qc2 Rad8 13.b4 Nd5 14.Bb2 White is in a reversed Sicilian.
3..d4 The Advance Variation 4.Nf3 Nc6 5.b4 a6 6.g3 Nf6 7.Bg2 Bg7 8.0-0 0-0 9.e3 Like a Benoni.
I just played a live match with black. My opponent started with d3. I've never played this opening before. But what's the name of the opening? What is the plan of the opening?
Because I don't know how to play, I played it just safe. My opponent made several mistakes, so I still don't know how to play it right. Can anyone help?
