Worst losses

Post some of your most hurting losses ever here, a blunder in the endgame, missed mate, whatever.

This is mine, being pinned down, I thought I had him with the knight on the second to last move, then I realized that 1. He could take with queen 2. I had blundered mate.

dude, it's alright, we all make blunders. I'll try to find a game where I made a big mistake, and believe me, it sucks. Don't feel bad about it. I didn't even know it was a mate until it popped up. I thought it was a king and queen fork lol. 

try playing rapid mode to improve ur chess ... it will help you to reduce making blunders.

That's what this game was. It was a rapid game. And yea, rapid helps your critical thinking. But you can't lose on time though.
