Only looked at three recent games.
No need to shell out good cash on a course.
You have Queen Syndrome.
You look for Queen moves all the time, often as early as move two
and you never trade her even if it means losing a piece.
Don't bring your Queen out so early.
Let the Knights and Bishops do the work in the opening.
You were actually a piece up and had a chance to swap off the Queens.
When ahead like this on material it's often a good to trade down.
Your opponent missed a mate in one in that game dragging it on for
another 15-16 moves. See if you can see it.
Another odd Queen move on move two and again you came out of this OK
because he loosened his K-side.
Here...Black to play.
Instead of 12...Qh5+
12...f3+ was far better and wins a piece.
Then when you ran out checks your opponent took over.
(he too missed a mate in one, see of you can see it).
Your early Queen sorties are going to get you into trouble.
You do not realise the danger you are putting yourself into because your
opponents have not punished you.
You won this. Well done.
If you had been playing me you would have been in tears on move 4.
Go and see what should have happened.
Leave Your Queen Alone
In the 1600's it was known that early Queen moves were dangerous.
This from Graco about 1620.
