The Amazon Attack (d4...Qd3)...what do you think of it? (real opening, not joke)??

d4 followed by a swift Qd3.......My usual strategy is a double fianchetto and advancing pawns on the queenside. Castling kingside.....It seems very playable and leads to good positions for white. Of course, there is the well known thought that you shouldn't bring out your queen too early, but hey I can't seem to find anything wrong here.

In fact, karpov played it against kasparov twice....soo it cannot be that horrible.

karpov has never played it according to mega database, post your games?

It's good against the Dutch and trash against everything else.

No Karpov... But there is this:

it's just tactical wrong it means almost nothing against but the Dutch

Well, playing Qd3 that early isn't exactly a loosing move, but one reason for keeping the queen home a bit longer is simply that you don't know yet what would be a good place for the queen. You might also want to leave space so the bishop on f1 can get out via the diagonal which goes through d3 (once the e-pawn has been moved).

This is briefly covered by Shiller in the book "taming wild chess openings" It is called the Siberian attack

1.d4 Nf6 2.Qd3 d5 3.Nc3 the idea behind it is to get in a quick e4 (preceded by f3) this just leads to equality for white though/ if black plays 3..g6 then 4.Bg5 Bg7 5.f3 stopping ..Bf5 

Or a Veresov where White has already committed to Qd3. 3... Nbd7 followed by 4... c5, by analogy with the Veresov, should be at least equality.

Amazon attack is rather meaningless but Dutch: Alapin makes sense.

The Amazon attack is perfectly sound and can transition to different positions.  The queen can pivot between the d3 and b3 squares.  According to the engine at top depth analysis, it is quite sound.  I usually do a double fianchetto, and it is difficult for black to find a game plan.  I have played like 15 games against 1800+ players and they have mostly been quite interesting games.  Also, I feel white can go for quick simplification with a slightly better endgame.

Need more expertise.

Read what I said above.  AND thank you to all the great chess players that commented above.  Cheers!

Um, 1. d4 d5 2. Qd3 Nf6 followed by ... c5 is at least equal for Black.

Correct yes, but it catches opponents by surprise, and it is actually totally sound to play as white, though a bit drawish.

I guess White wants to sneak into some kind of Veresov after 1.d4 d5 2.Qd3 Nf6 3.Bg5. Maybe you get a Qb5+ cheapo in blitz.

One must be objective, I look at your opening Amazon Attack; its quite tricky and dangerous, its worth having in ones repertoire, especially on otb play. Not so easy to play the King's Indian defense and can lead to Pirc like position that black might not like.

I used this suggestion and tried 2. Qd3 in one of games (on chess-land, still in progress).

The Amazon attack can transposition to different openings AND it takes your opponent by surprise.  

My technique is to do a double fianchetto.

There is this story that the great chess composer and puzzle inventor Samuel Loyd was once challenged by someone who thought that he could easily draw as Black by just copying White's moves. Guess how the game went.
