takeback 

Usage: takeback <n>

The "takeback" Requests a takeback of 'n' half-moves in the current game.

EXAMPLE
-------

takeback
     Here's an example: suppose you are playing White and your opponent has
     just placed a piece on a square where it can be easily captured, and you
     capture it. Your opponent might realize the weak move he/she made and
     request "takeback 2" so that he/she doesn't lose material so easily. If
     you wish, you can accept the "takeback 2" request and continue the game
     from the previous position in the game. Both moves would be reversed,
     and it would be Black's move to make. Also the time would be as it was
     (that is, you would not lose any time).

SPECIAL NOTES
-------------

 o If 'n' is omitted then 1 is assumed. A "half-move" is defined as a move by
   one player. To request that the last move made be changed (whether you
   were the one to move last or your opponent moved last), you would request
   takeback. If you wanted to change the last move made as well as the move
   prior to that, request takeback 2.

 o To accept a take back offer, type accept or type the same takeback offer
   (such as takeback or takeback 2). Use decline to decline the takeback
   request. Takeback requests are automatically removed when play continues.
   Use withdraw to withdraw a pending takeback request.

 o If you issue a takeback and move, then the number of moves you request to
   takeback will be incremented by 1. This is so you don't have to wait on
   your turn for the opponent to accept or to have to issue another takeback.
   If your opponent moves instead of accepting the takeback, it is removed.

 o Takeback requests are offers. They may be accepted or declined. Your
   opponent is under no obligation of any kind to accept your takeback
   request, even if you say your last move was a mouse slip.

 o If your opponent has his notakeback variable set to on, the request will
   automatically be declined.
