yes there should be such an option......on chesscube you can request your opponent to take back your last move
Taking moves back?

Could I direct your attention towards previous topics (e.g. http://www.chess.com/forum/view/general/taking-back-a-move) where ideas about undoing or cancelling a move have been discussed, including the logistics, and the pros and cons.
The facility of TAKING BACK has now been introduced within another form of unrated game. From Start New Game, under Show more advanced options, the Rated option offers a dropdown menu now containing THREE items: Rated game, Unrated game and Takeback game.
Within a TAKEBACK game, an extra button "TAKEBACK" is displayed, alongside SUBMIT MOVE, OFFER DRAW, CONDITIONAL MOVES. Both sides can takeback at any time. When it is your move, clicking on TAKEBACK undoes your opponent's previous move - and it becomes their turn again. When it is NOT your move, clicking on TAKEBACK undoes your previous move - and it becomes your turn again. This can be repeated all the way back to the beginning of the game. You can't undo CHECKMATE (or once the game is over). http://www.chess.com/forum/view/community/new-features--fixes---jan-14-2008
I'm wondering if there's a way of taking moves back.
I was having an interesting "Live Chess" game a few minutes ago, when the other guy blundered away his queen. In most situations, I'm more interested in playing a position out rather than getting an instant win and a handful of points.
Maybe a retraction could result in a forfeit; then, if both players agree, the game could be back-tracked to move "x" (and times reinstated) and the moves played again.
(If this is already covered somewhere, my apologies.)
