How can I convert winning positions?

Hello! I find that most of my losses are me throwing away a decent or winning position, and I want to change that. I’ve been getting good results either way, my rating is around 1850, but this is holding me back. Funnily enough my opponents sat I’m resourceful in losing positions. So how do I win won games and avoid losing neutral/decent ones?

Thanks in advance for any tips!

Avoid “easy” or single-purpose threats. Try to make moves with multiple purposes, the kind that bother your opponent more and limit their options

Is the article How To Convert An Advantage by Robert Ramirez helpful?

The title reminded me of my ability to convert my winning positions into losing positions

I also have this ability.

I’ll check it out

If you have a material advantage, the winning methods include:

1. Exchanging pieces, not pawns, to simplify to an elementary winning endgame. 
2. Attacking something, because you may have more attackers than there are defenders.
3. using threats of exchanging pieces to grab more space. Eventually, your extra material and space will provide winning tactics.

if you have a spatial advantage, keep improving the position of your pieces before you look for a decisive breakthrough. A common mistake is to try to win too early, before you have maximized the positions of your pieces. If your opponent’s position is cramped, avoid exchanges that ease his position, unless there is a clear benefit.

if you have a temporal advantage (a big lead in development), try to open the position for an attack and avoid exchanges. In such positions, material is less important than the speed with which you can muster up an attack.

Didn’t expect an NM in here, thanks!

I mean I'm lower rated than you, but everyone has and knows this problem.

Basically dont relax, stay concentrated, stay wary, keep playing good chess.

And if you see chances to trade, yes thats a basic strategy to improve your relative strength, but dont trade your good pieces for the opponents bad ones.

I dont fully understand what the NM said. Space is just one aspect in which you can have the advantage but to really constrict your opponent this way you have to limit their space by a lot, the less pieces are left.

I do believe I understand what the NM said, although it is true that there are lots of imbalances in chess that can be tipped in your favor.

I reached 1904! I kept having trouble converting all the way there though

Don’t worry about it, other chess players are also likely visiting this forum for advice so any tips are appreciated, even if they are “obvious.” :)
