worst move ever

What is your worst move ever? (I've seen GM games with horrible moves, a few of which come to mind. ie Capablanca blundered away a piece in the opening!, Adams gave Nakamura a drawing move in a winning position, and neither of them saw it!) Or what winning positions have you resigned in? I'd like to hear responces. Also, someone else posted a site where Grandmasters have resigned easily winning positions (Kasparov resigned a drawn position). I looked through those and my favorite on is where a funny conversation takes place. If you want to see the position just go to: http://www.xs4all.nl/~timkr/chess2/resigntxt.htm#09
"This was the final position of a decisive last round game; by winning it White would have tied for the championship. According to the story, Keller said: 'It's over.'
'I prefer to play on a little,' Schlemmer said.
'No, I mean I'm resigning.'" They both thought they were losing! Keller should have thought a minute after Schlemmer asked to play on before saying 'I'm resigning'

Well I've searched and searched. And I just can't find one. Sorry.

LOL. The worst move I've made (not because it leads to an immediate mate, although it can) is in this position (I've posted this before):

white to move and lose.[fen]3b2Q1/2nkpQ2/2rppp1Q/8/1Qn3Q1/3Q2b1/3PNQb1/3K4 b - - 0 1[/fen]

Here I played Qb2?????? (a question mark for each queen I lose seems reasonable) In terms of losing material, not counting the king, can this move be matched?

I'd say the brilliant 1 f3, followed by g4 you posted about in the general forum would have to be the winner.

I cannot post the position, but in a real time tournament, I sacked a rook to force a pertetual check, but my opponent (to my infinite shock and delight) did not realise he could take the sacked piece and believed me to be forcing mate and so thus resigned, giving me 3.5/5 in a tournament

I must appologize, Coconut, as I am new to redhotpawn (bluecoldqueen?) the game I played is not on this site. Here is the pgn though: 1. e4 c5 2. Nf3 d6 3. Nc3 a6 4. Bc4 Bg4 5. O-O b5 6. Be6 fxe6 7. b3 h5 8. Bb2 Rh6 9. Nd5 Rf6 10. Nc7+ Kd7 11. Nd5 Rxf3 12. gxf3 Bh3 13. f4 a5 14. Qg4 Na6 15. Qf5 Rc8 16. Qxf8 Nf6 17. f5 Ng4 18. f6 Rc6 19. f7 b4 20. c3 h4 21. Rfe1 Qb6 22.

Qff7 Bh4 68. Qfh5 Bg3 69. f5 Bh4 70. f6 Bg3 71. f7 Bh4 72. Qa3 Bg3 73. Qd3 Bh4 74. Qbe3 Bg3 75. Qef3 Bh4 76. Qfg4 Bg3 77. Qb4 Bh4 78. Nf6+ gxf6 79. f8=N+ Kc8 80. Ng6 Kd7 81. Nf4 Bg3 82. Ne2 Bh4 83. Qh8h7 Bg3 84. Q7f7 Bh4 85. Qh6 Bg3 In this position I (accidentally?) blundered away 7 queens (or my king in 5 moves if my opponent so chooses, but he didn't) by playing Qb2?????? (this is one of three possible moves that lose the game)

This is what I call a royal fork:

Although it is possible to fork the king and 6 queens (not seven, or else from what square would the knight move from? (and of course the king can't move into check)😉) I decided to post this instead. Black "only" wins one queen for a knight.

I'm sure as a school kid I made all sorts of whopping blunders. Then came a few decades of not playing chess, before finding this site. At RHP, my worst move was surely the use of my knight to capture at move 8 of Game 710590. That move led to my opponent stripping my king plumb nekkid in the opening. I don't know if I could even have gotten a draw after that move.

Check out this game! This GM makes the worst move on the board, the only move to allow mate in one!http://www.chessgames.com/perl/chessgame?gid=1069122

With this, and your other post, claiming you blundered away quite a few queens in a move... i suppose you meant worst FANTASY move you could ever play? theres no way you ever played these in a game, and just making up an entire game to try and claim you did seems a bit pathetic to me

Pual Dirac I think your worst move was Caslting too early in that game and dropping your center pawn. The second worse move was moving your rook away from protecting the fpawn, instead of developing a knight. Instead of castling,developing night would have been best also.
