Worst blunders you’ve made?


Forgot about en passant during a winning end game. Or getting lolli's mated after getting a second queen.
Once I played against a 500 rated player and played e4 on the first move, and then I noticed his rating and went to abort, but right before I clicked, he moved and instead I clicked resign

I was playing the Vienna gambit(by far my favorite opening, fits my style so much) and my opponent accepted(in case you don't know, that is never good). My opponent did not want to retreat his knight and instead played Ng4, so I took his knight. Long story short, I didn't see the discovered attack.

all of them
about to mate in one, but had to defend my king first and got checkmated
resigned on a winning position
missed mate in one and lost
hung a queen
a few days ago on a drunken tilt I fell for a variation of the scholars mate lol

I completely understand your mistake but damn was this painful to see
literally most of my lost games are simply embarrassing, pls don't look into my stats and see my losses pls.
I’ll start. I once was up 9 and thought there was no way my opponent could beat me since I was up so much. While I was focused on trying to take his pawns, he spent some moves setting up a mate. I was shocked when I saw I lost. (Props to my opponent tho for finding the mate) so what are your worst blinders?
