Blunder of the 21st century ??

How can a player of Kramnik's caliber, a world champion who hovers around the Elo 2800 mark, overlook a mate in one move? Here's his 2006 public game against Deep Fritz: en.lichess.org/eR8gEWnG#67

It's truly unbelievable... any other great examples at the top level in the last ten years?

@Manglecopter -- newcomers to chess will not have known of that game. It was surprising to me that a top player of the world could have overlooked being mated in one move, something a newbie could solve in a CAPTCHA to make a post here. At any rate, your hostility is clearly unwarranted on this forum -- moreover, you *FAILED* in responding to the key question of this thread.

I tought the blunder of the 21st century occured in the famous game noob2chess-amurat, 01-July-2016 on move 44 (en.lichess.org/3cMpnP9y/black#88). Instead of 44...Rg5+ winning the Queen and the game, Black played 44...Rc2 and got checkmated by 45.Qb7# on the next move.
But joking aside -- that happens to all of us...

Yes everyone blunders

haha that is a funny one happycruncher how many games did you look through to find such a fitting situation? probably not many :')

Here's another famous example, I happen to know the White player, (he is usually not that bad ...) and he was quite happy with 17.Qxb4 until he saw the response: en.lichess.org/QMin01UG#32 :)

Ivanchuk missed 29. Qxh1# against Anand. It is blitz, and black had ~60 seconds on his clock. (You can find it on youtube, smth like "Ivanchuk missed mate in one")
