Elite GMs overlooking mate in ones

I never thought GMs could blunder mate in ones, but in turns out that even elite GMs have overlooked mate in ones. To be fair, a few games were blitz games or had time trouble. I could of made this compilation bigger by including queen drops but I think mate in ones are the worst. So the next time you drop your a piece or even overlook mate in one, don't feel too bad about yourself. 

Comment on which is the most embarrassing blunder. In my opinion, it is Kramnik vs Deep Fritz since he was #1 and World Champ in a classical game. If you enjoyed this post, comment, share this with your friends, and follow me.
