Free Game Analysis!

I felt I played this pretty well, but I'm curious about one move in particular. The post-game analysis said that my 7. Qxd4 move was a blunder. I get that developing the knight may have been better and that moving the queen may have been only a good move or even a mistake, but I don't see why it's a blunder.

Hey everyone! Here is the most recent upload, I had previously thought this forum had died but I guess not! Looks like I have some work to do, here is the first one.

Yeah sure! Add it to the queue!

Any one of them is fine. How about my most recent loss?
Which one? Would you mind posting it?

hi a few days ago I stumbled upon this chess player who is exceptionally good, as most of his/her games have really high accuracies above 99. basically, i played a game against him/her but i did not know where i started to go wrong. i dont believe there was one decisive moment in the game where i started to go into a losing position. id very much appreciate it if u analyzed this game between me and @batangamerica30.
btw i was playing black

i think Bxg3 was the main inaccuracy there, your dark square bishop was way more important then his knight.

Anyone else find this thread a bit arrogant? An intermediate player offering game analysis while we have free computers to do it. I dont understand it.

heres the thing... you dont have to post here.. if you wanna use computers to do the analysis rather than this its perfectly fine... you can go do that instead of posting that comment.. and he's not being arrogant.. he never said once that his analysis is better than engines.. hes merely offering his time to the community and make it into a video and post on youtube ... FOR FREE...
Hello,
I just had great game and I hope that you will find it interesting for analysis
