Generally, at the beginner to mid rating range, most blunders may occur at the middlegame. So, to improve your middlegame at lower levels will be to punish and eliminate your and your opponent's blunders. This is unlike many games at the higher/highest level (2200+) as to improve in their middlegame will generally mean to generate winning ideas and plans during the middlegame. So don't get confused by what 'improving your middlegame' means because it will mean different things at different levels. Again, at lower levels, it will be to punish your opponent's blunders by looking through the forcing move checklist for your own moves. And to eliminate your own blunders by seeing your opponent's forcing moves if you play a certain move and ensuring that all those treats are defended. This is just my experience/opinion though. IMO, @RussBell 's blogs are also good, so checks those out as well

"Sometimes I have a decent advantage over the other player but I have no idea what to do with it" ++ If you are up material, then trade pieces, not pawns so the relative importance of your advantage grows and you can win the endgame. If your pieces are better developed into play and/or if you control the central squares, then attack his king.
"Anyway my question is what do you do in the mid game?" Improve the position of your worst piece. Trade your bad pieces for his good pieces. Put knights on outposts and rooks on open files. Be careful with pawn moves: pawns cannot go back.


They say... you should make right strategical (positional) moves in the mid game.
Chess masters do them even intuitively.
They enhance their position constantly.

train puzzle rushes every day until you stop dropping pieces and pawns for free.
follow this plan: 😎
1. gain a free piece.
2. regroup your pieces.
3. trade equal pieces off.
4. take your opponent's pawns.
5. support & queen some pawns.
6. checkmate with your extra queens.

I have the same problem. I've been picking squares I want to attack and look for pieces to bring into position to do that. I also look for free pieces the opponent is giving me. Some basic tactics like pinning and forking help to get you up further material. I still don't know how to checkmate very well. But the more material advantage the better.
