What are some famous resignations when the resigning player had a winner or won position?

In Chess Companion they have this example from a master game:

Negesy-Honfi

which one resigned?

White resigned after Qxa2

I forget the game, but theres a position where one side gets a great double attack (offering a queen) with Bh2!

forget the players names though

Probably Kasparov resigning against Deep Blue, certainly the most famous.

There are quite a few famous resignations. I recall seeing one as an exersoze onece... I think It was Tal vs sombody and it was a K+p endgame with 4 pawns a piece. it looked very dangerous and that black had a won game, but in fact white could force a win but the guy playing white resigned...

Isn't it Bg1 while the black queen threatens h2? That was pretty awesome

yeah that was it! sorry forgot which piece was going to which square..

do you know what game that was?

 This was one of the puzzles from a book I read recently, can't remember the players etc but I will look it up later when I get home. It definately falls into this category. The Bg1 is clearly winning not just drawing, I spotted it within a few minutes so I'm surprised that a master didn't.

And while he didn't resign, but accepted a draw offer, Shirov just missed sharing the Corus-win with Carlsen, in a totally won position in the last round - after a super-blunder by Dominguez.

In Shirov's defence: time pressure, but you have to feel sorry for the guy.

These examples are good, shame they are not in moveable format to fully understand what is being said.

 It was Von Popiel versus Marco, Monte Carlo 1902.

Nice link Steinwitz, the game maulmorphy was talking about is in the number one spot. It's kind of understandable that it was missed because that reverse bishop attack is a bit counter-intuitive.

Kasparov missing the draw in the second game with Deep Blue was pretty epic, but it was so hard to see it! It's in one of the chess mentor lesson devoted to the Kasparov-Deep Blue duel. There was some very subtle and brilliant moves that needed to be played.

Here's a link to a .zip with all the Resign setups. You'll also find the link at the bottom of the page I linked to above:
