Colossal Blunders: Please Post Yours Here

That's what happens when you take your opponent's Queen on move 11 and then you decide you can win the game with your brain switched off.

That game was upsetting to watch

Oh yeah, you can't imagine my emotions after it ended.

Ouch!  This game definitely belongs on this forum. 

Thanks for providing a good laugh.

You're welcome. 

And if anything, it was a highly instructional game for me: never play when you're tilted lol

Yes, missing mate in one and instead allowing mate in one can be rather frustrating.

Thanks for sharing.

Once I played g4+??????????????????????????????????????????????????????? that FORCED MY OPPONENT TO CHECKMATE ME. I mean ...Qxg4# was the only legal move.

Classic selfmate style!

I was too focused on trying to attack the pawn that I forgot that the queen was on f2 and not f3 lol

(Not to mention that Qh4 would've been a terrible move even if it wasn't for the queen blunder)

Another stupid oversight. Seems I'm quite good at these. At least here I was a bit low on time.

I was trying to do Bg5# 💀💀💀

My opponent accidentally stalemated though, so it wasn't a total loss

Not mine, but well worth looking at.

Garcia vs Ivkov, Havana 1965 was arguably the worst blunder in the entire 500-odd-year history of chess.

In 1965 Grandmaster Ivkov was on a roll! He had won several strong tournaments, and even qualified for the Candidates Matches to play off for the World Chess Championship.

Playing in Havana Cuba, he was half a point ahead of everybody going into the last few rounds, after already beating both Fischer and Smyslov. Paired against the tournament tail-ender Garcia it looked like nothing could stop him. Soon he was the exchange and three Pawns ahead.

Six points ahead. All he needed to do was to make a few more moves and reach the move-40 time control... and then...

Check out his 36th move, 36. ... d3.

One of the most ghastly blunders on record.

Ivkov was never the same after this game. Seriously... it BROKE him. He never qualified for the Candidates again.

Ouch!

Thanks for sharing!

I was playing bullet, so i was really focused on his time, but one missclick is all it takes to mess up a game. Luckily i was playing on my fun account and not my serious one.

I took a knight. Who needs horses anyway when you have me, a braindead idiot who fails to notice the most obvious threats?

I'm gonna go hibernate for a month out of embarrassment. See y'all later. /s
