No this is the Queen pawn opening. The pawn moving is in front of the queen.

Yes, its the queens pawn game.

It is not really a gambit because White will get it back (if he wants to) even though it i called the Queen's Gambit.

This move doesn't really deserve a exclamatory, it's like giving one to 1.e4.

If you like to play the QG opening (1d4 d5 2c4) then you should know what to play if black foolishly tries to defend the c4 pawn. After 2 c4 dxc4 3 e3 (attacking the c4 pawn with the bishop) 3 ... b5? 4 a4 (if 4...a6 the pawn can be taken because then the a pawn is pinned) c6? 5 axb5 cxb5 6Qf3 loses a piece in the corner.

No. The Benoni defense arises from the Indian 1.d4 Nf6 2.c4 c5. The move played here is very transpositional.

This is not a good move; it breaks the principle "don't put your knight in front of your c-pawn in double d-pawn openings." To open a file for his rooks, white needs to play a break move (a move that attacks a fixed pawn with a pawn). This blocks c2-c4, which should be played here. Edit: a quote I heard: "Most players play the opening like grandmasters, the middlegame like average players and the endgame like beginners."

No. The Two Knights Defense is 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6.

The two knight defense is with the e-pawn. I have to agree with cplusplus here, with double d-pawns the game is calling for a c4 or c5 break.

I think this is a bit too ambitious. It is too early in the game for a decent attack. Development and castling is called for.

Black is just a copy cat.

This move is an inaccuracy because it blocks in the c1-bishop. Edit: 5.e4 was not best. It's not safe. That's why 3.Nc3 is inaccurate: the only available break is e4, which is much harder to play than c2-c4.

I think the blacks dsb will move to b4, that's why the white's dsb may be best placed on d2.

This is an interesting idea, but the pawn on d4 looks fixed. The scope of the dsb won't have much on g7. It wouldn't be my choice, but if there is a battle on the center later, then this can be a good choice.

No, it loses a pawn. After 6...dxe4, white does not have to capture with 7.Nxe4?? Nxe4 losing a piece, and should instead limit his losses to a pawn.

not only does this lose a pawn, it also loses the battle on d4, therefore the scope of the dsb on g7 will will be much better. Better is development of lsb and castle.

Don't make unnecessary pawn moves in the opening. White's last move was e3-e4, you should think, "Is that safe for him? Can I win material by force?" Here, 6...dxe4 wins a pawn, since 7.Nxe4? Nxe4 wins you a piece. Edit: 6.e4 was NOT safe!

Blunder. This move weakens the g5 square, because that square cannot be attacked by a pawn easy. And it also neglects to take a pawn and open the center.

King safety is not a factor is the evaluation of doubled pawns. Here, black would be happy if white played 8.Bxc6+ bxc6, because that brings a pawn towards the center, where there is still tension, and gives black the bishop pair advantage (worth ½ pawn) Doubled pawns are bad if they are weak and can be effectively attacked. Here the doubled pawns are not weak because if white plays 9.e5, black gets the ...c5 break twice, and if white plays 9.exd5, then black has 9...cxd5 undoubling the c-pawns with an extra pawn in the center instead of on the flank, and the ...c5 break. (White's e4-pawn is still unsafe.)

Well I kind of agree with cplusplus but I think the threat is not 8Bxc6 but 8Ne5 attacking the knight on c6 twice. Therefore I don't think this move is that bad. But I think 7e5 is a very strong move, limiting blacks possibilities and hindering development, while creating a strong center for white with a lot of space.

I think reachforgoals meant 'to break the pin on my knight to the king' when she said 'so my king is safe'. Jkarp: King safety is about whether you can attack the king or not, although pawn shield is somewhat important. Take this diagram as an example: Black's king is castled but is not safe because white can attack it. White's king, though exposed, is safe because black cannot attack it. If your king is exposed but cannot be effectively attacked, your king is safe, because your opponent does not have any way to checkmate you. By the way the e4=pawn is still unsafe

Its not true what you say jkarp. White could not play this move earlier because black had two defenders, his knight on f6 and the queen on d8. But because of the last move Bd7 black does not defend the d5 square with two pieces.

The knight on c6 is unsafe.

Much more important than development right now (NOTE: this is only at this moment, but not always) is keeping pieces on the board. This simply loses the c6 knight for a pawn. When playing against higher ratings, black can already resign here!

No, you are down a piece.

Keep the pieces on the board! White should have retreated his bishop, its is much more important than development right now!
