The Name for Taking Too Long on a Move and then Botching It

the slowness of mediocrity feels just about right

Petrosian maybe? (He once took 45 minutes against Fischer in a position he had prepared beforehand, only to reject the most obvious and best continuation (which was good for him), and go on to lose.)

I call it "pulling a cris angel" since it seems to be one of my favorite things to do. Joking aside, isn't it just a blunder? Perhaps over thinking? Or did you actually hear of a specific word? It's interesting.
I've always called it over-thinking the position. It can also be tunnel-vision if you focus on a particular variation for a long time only to find out your opponent has a different move that torpedoes the whole thing.
OK. Some suggestions:
Taimanovism : named after Taimanov when he spent ages on obvious moves and prepared moves in his 0-6 loss to Fischer in the 1972 Wch candidates match.
Rodinism: named after the Rodin statue of "the thinker".

Hamletism: this is how his fatal flaw of procrastination would have played out on a chess board.

I think Kotov Syndrome is best, because Kotov specifically mentions this in Think Like a Grandmaster.

It's called the Dodd Gambit. You take too long on a move and then botch it with a losing move on the spot. Your opponent then mates you or wins the queen. You then knock all the chess pieces off the wooden board, pick up the board and use it to hit your opponent over the head while saying "Dodd Gambit!"

The Kotov passage is below. It comes after he has talked about the previous thirty minutes of analysis you've done for the move, analysing all the different possibilities after moving either the rook or the knight.
At this point you glance at the clock. "My goodness! Already 30 minutes gone on thinking whether to move the rook or the knight." If it goes on like this you'll really be in time trouble. And then suddenly you are struck by the happy idea -- why move rook or knight? "What about Bb1?" And without any more ado, without any analysis at all you move the bishop, just like that, with hardly any consideration at all.
Hi Everyone,
I read somewhere on this site of a name (I think it was a specific chess player's name) for when a chess player takes way too long on a single move and then botches it. Anyone remember the name?
