Thanks in advance!,

I'm pretty much in the same boat you are in. I've noticed that I do well until the late middlegame early endgame when either I miss some tactic or sometimes I don't know the plan I should develop.
I've recently started playing 15 minute games as recommended by IM John Bartholomew on chess.com for the best way to improve. Play 15 minute games. After the game, analyze on your own quickly, then go through again more deeply, then check with the engine. I'm doing this and I also got two books as recommended by him. "From Amateur to IM" and "Tune your chess tactics antenna." I'm going to be going through these along with doing the daily tactics puzzles on here.
This is my study and development plan. I think reviewing my games will and has help/ed a lot.
I also somewhat disagree with the global adage of bullet and blitz is bad. It has it's place. It has actually helped me prepare for tournaments, in that I was able to play more games and thus see all the different openings more quickly that opponents could throw at me, and then prepare. Now I'm slowing my games down.
Here are a few examples of books with annotated games:

Hello, I am a 1912 rated player and I keep playing really good up to the late middleggame. The problem is that I blunder a lot. For example, in the last tournament I played a 2100 and won the exchange and a pawn and couldn't convert. Another example is in a OCB ending that was drawn against a 2100 and I knew that all I had to do was move back and forth, yet I inexplicably didn't.
My question is: How can I study to help my late middlegame and prevent blunders?
