Correct. ICC:
***** DRAW *****
Command : draw
Examples: draw -- offers a draw to your opponent, or terminates the
game in a draw if the correct conditions hold.
draw Joe -- offers a draw in your stored game with Joe, and
sends him a message with the offer.
This command ends the game in a draw if any of the following conditions
are true:
* Your opponent offered you a draw and you have not moved since then.
* The current position (or the one that you move into if you offer the
draw and then move) has occurred at least twice before. Everything
must be EXACTLY the same, including the person to move, castling
privileges, en passant possibilites, etc.
* The last 50 moves (50 moves for each person) do not contain any
captures or pawn moves.
If none of these conditions hold, then the command offers a draw to the
opponent.
Remember, you must type "draw" to claim a draw by "repetition" or the
"50-move rule". The game does not end automatically. This is the same
as in tournament chess, where must ask the TD or your opponent for
the draw.
