This one is probably for Dave_L..

A user made a move in haste, and would like to take it back.
It's a friendly game, when we play f2f it's generally allowed.

Is there some way for me ( as admin ) to remove his last move?


- As a work around, we could start a new game using FEN to set the board up. but then we wouldn't have the full move list for the generated PGN, ( I like to analize my games afterward ). Yes, I could further, just type it in, but...
i'm, lazy

The only way would be to manually change the database columns for that game. These are the columns that potentially require changing:

start_date (if move was first move of game)
last_date (*)
fen_piece_placement (*)
fen_active_color (*)
fen_castling_availability (if affected)
fen_en_passant_target_square (if affected)
fen_halfmove_clock (if affected)
fen_fullmove_number (if black moved)
pgn_result (if move caused game to end)
pgn_movetext (*)
offer_draw (if affected)
suspended (if affected)

(*) - definitely requires changing

Ok, I see how that works now.

I talked with my other play, and he actually wants to just play it out, if we can star anouther ate the same place.

But this info was valueable...
I think I'll modify the pgn_movetext on the new game to have the starting moves from the previous game, that way we can port it into chessmaster for analisis.

( I have earlier worked with a Perl script that walked the PGN file as how it saves games ( text format ) and I could just delete the move. This is a little more complex, but better. With FEN setup We can play some varients, like Fischer Random or Mongredian Chess or many others. Very Cool. )
