What was your biggest chess achievement?

Defeating a WIM in bullet Chess960 I guess.?

Every win is an achievement, jusy as every loss is a failure

It was probably when I was 3 or 4 years old, and figured out how the Knight moved.

It went downhill afterwards.

For me it was objectively state champion in 1976. That felt good.
What felt even better was winning a tournament the year before right as my car's tranny went out and having the first prize exactly cover a tranny rebuild.
What feels best is to play an interesting game so complicated that neither player knows what is going on and when the smoke clear to be on top.
