Chess Pattern
Why do I lose winning positions?
You were winning, then you weren't. Finding the move where the advantage slipped is how you learn to hold a lead.
What the games show

What it is
This flags moves played from a clearly winning position that hand a big chunk of the advantage — or the whole game — back to the opponent. Often it's relaxing, rushing, or grabbing more when consolidating was enough.
Why it matters
Converting won positions is a distinct skill from reaching them, and it's where a lot of rating hides. The same relaxation mistake tends to recur, so seeing your collapses side by side is unusually instructive.
How to recognize it
When you're winning, switch modes: stop looking for the knockout and start removing counterplay. Trade pieces (not pawns), keep your king safe, and double-check that the crushing move isn't also a careless one.
