Why is this a blunder?

It seems to me, if I moved the B to attack the queen then QxB or NxB, I thought it better to trade for a Pawn.The N might have been taken but I still get the Q. As it worked out, Queen retreated and I still lost my B to the N. A mistake, perhaps but a blunder...?

I've no idea what you're talking about tbh.

Why is moving pawn to e5 worse than winning a queen, is your question?

As it played out, I did take the B to g5 and then BxQe6. NxBe6.  The K would not be in check if Q xB g5. It looks to me like both my B & black Q were goners how ever I played it.

Foolishly, I thought to take the Queen with Pawns! BTW, I, very often, don't know what I'm talking about. I only started playing Dec.6. I did win the Queen and CM in the end. I try to avoid exposing stronger pieces if I do not need to do so. Some of you with more game experience  can tend to arrogance and ridicule that does not inspire beginners to want to ask anything.
