Can somebody please explain how this move was a blunder?

Its a blunder because your coming out with the queen too early. The computer wants you to develop your other pieces 1st, and castle..... before bringing out the big guns.

It is very hard to say whether you are trolling or joking.

I'll joke sometimes but I stand by my statement. I usually don't comment in chess threads but that's my understanding of the board position that the OP gave. Unlike you, I'm only 1300-1400 on a good day.

HI All. So I played this game. I'm rated 458 and my opponent was 450. I'm playing white and played the move Qh6+ but the game analysis said this was a blunder and I should have played Bxg5. His next move was ke7 followed by me mating with qf7. I don't understand how the analysis said my queen move was a blunder?
Bringing the Queen out isn't too bad, but there's a knight sitting there. You need to take on g5 with your bishop and pin the knight
Therefore, bxg5 is the only good move I'm seeing here (on a quick glance). The knight capture makes it a serious blunder, and the black pieces will easily win the game if played at least as well as the white pieces (without blundering a queen).

Like everyone else has noted, it was a very costly, unfortunate scenario. It feels like the climax of a story.
The computer suggests this as a blunder because with Black's best move, White loses the queen.
I'm sure Black's follow up move, Ke7, is a counter-blunder in the analysis.

me too. and usually a 1300-1400 player will realize that the reason is not beacuse the computer wants you to develop first but because it hangs a queen.

judging by the ratings black probably would blunder a queen back

So you are saying that you thought about the position... and you did not notice that Qh5+ simply hangs the queen.
And then days later you gave it another thought... and you still didn't notice it, even though a lot of guys mentioned it in the thread.
Sorry, I'm not buying that.
