Queen trap (I think no mistakes in this short game)

Sorry for the stupid comment, but after 7...Qxb2?? what is wrong with 8.Na4 which wins the queen outright?

Yes, after 8>Na4 Black's best is to trade his Queen for a Rook. A bit embarrassing to miss this, but I'm sure I've missed similar Queen traps in my own games.

As far as I'm concerned, the only thing it shows is that you missed 8.Na4.

In that particular position it's not important, as white has 4-5 winning moves, but still...

I doubt I've eve played a game in my life where I haven't missed a thing or two (or ten!), we all do. There's no reason to get all defensive when someone points it out. In fact, when an IM takes time to look over your game, I think the appropriate response is, "Thanks."

I will concur with everyone that mentioned that 8.Na4 was the best move to play as the black Queen was lost and game over usually.

A pawn gain playing 11.Bxa7 never covers the mistake of not playing 8.Na4.

In my opinion the issue of this game is much deeper than not playing the right move 8.Na4.

The issue in this game is that Black lacks the understanding of the opening principles that dictates that one must develop back row pieces. And I will here bypass my usual long explanations as to why and I will just mention: control of center squares directly or indirectly with quick positioning of pieces protected when developed to launch an early attack on the opponent King and to put the most valuable piece on the board the King to safety, there you have it in a nutshell.

The black Queen had too many trips on the board wasting time and tempi and eventually ended up in loosing the equivalent of a full pawn after 3 backtracks of moves.

Move 3  by Black piece was 3…Qxc5 , better was black playing  Nc6 blocking the advance of the White c5 pawn or Nf6 developing a piece to be able to castle quickly King side.

5…black plays d6, again a lack of opening understanding better is to play Nc6 to protect or cover the eventual pawn move to e5 later in the game or just play 5…e5 to take control of the center and stop the white pawn in e4 advancing, next follows castling in a few moves on both sides usually.

7….Black plays Qxb2 we all know this move was loaded for Black, meaning that trouble was ahead,  The alternative was to play Qa5 another tempo loss and retreat back home to c7 or plat e5 next move this needs further analysis.

Black plays 8…Na6, why? Nc6 or e5 explained above where better moves to play.

Bottom line the lack of understanding on why and how pieces move in the opening is the result of this game ending.

If you believe that you understand chess then play chess 960 or Fischer’s variation available on this site when you challenge an opponent and you will very quickly understand or not if you understand chess principles of opening and piece positioning. Anyone up for an unrated game of chess960, just challenge me?

Look man Iam not IM or GM ((cause I didnot participate in any of international tournments )) But this don't mean that Iam bad.
To be fair your comment is the best and no wrong in any of you said :)
