Hi. From what I can see you traded queens and did not blunder and lose yours? Maybe you mean that you had to take with your King and couldn't castle?
Wining without a Queen
Sort:
It's not necessarily disastruous to make that queen trade early. You lose the ability to castle, as mentioned above, but otherwise, you can still setup a good position despite this trade, particularly because their most mobile piece is also gone.
I take a long time to look at board states (I made a thread on why today asking for advice, given my particular circumstances), but it appeared that you played well given his lack of setting up a reasonable position and allowing you to develop from his superfluous bishop movement & checks (5. Bb5, your pawn press in response, to his retreat, and 8. Bg5+, only to return his bishop at 9. Bd2, to 10. Ba5+, yet again to retreat his bishop, 11. Bc3)
He does manage to take your rook, but you defend well and press on to victory.
I don't think this is a problem in absolute terms for you; I would simply recognize that queen trades happen sometimes and continue to improve your play (as we all try to do!)
Thats a queen trade, not a blunder.
wrong game
sorry
You didn't lose your queen.
You did a queen exchange.
However, you did lose on the rook exchange.
You did a rook vs bishop exchange.
A rook is worth 5 points
A bishop is worth 3 points.
Thus, usually the exchange would be considered unfavorable.
In your game it was an unfavorable exchange.
Since you give your opponent 2 points worth of material advantage.
Today I played a game that I blundered and lost a Queen. Most times Iwould resighn but I continued for a few moves to find some serious blunders. I dont even know if his mouse was working or not. Here is the game:
