I wish I had more experience with move-controls (non-sudden death).
Why isn’t there a rule for Both Flags down in Non-Sudden Death? What happens if neither player makes the required number of moves within the specified time? I’m assuming it would be a draw, but I’d like clarification.
In a non-sudden death time control segment, the game continues and the assumption is that the next move is the first move of the next time control segment.
16T. Both players exceed time control.
If both players exceed the time control, no claim of time forfeit is possible. In a non-sudden death control, the game continues. In a sudden death control, the game is drawn. See also 13C6, Claimants clock; 13C13, Player out of time cannot claim; 14G, Both flags down in sudden death; 14G2, Players apparently unaware of situation; and 16Y, Assisting players with time management prohibited.
That is not quite correct. The game continues. If the move number is known then that is the move number. If the move number is not known then it is assumed to be the start of the next time control.
Example 1
40/120, 20/60, SD/60.
Time scramble starting at move 25. No certainty as to what the actual move number is. The next move number is considered to be 41 (need to complete move 60 before the next flag).
Example 2
40/120, 20/60, SD/60.
Time scramble starting at move 25. Reconstruction determines that the dual flagging occurred on move 32. The next move number is considered to be 33 (still need to complete move 60 before the next flag).
Example 3
40/120, 20/60, SD/60
Time scramble starting at move 25. Reconstruction determines that the dual flagging was noticed on move 44 (the dual flagging may have occurred before move 40 and not been noticed, and the players wouldn’t have been certain even at move 44 whether or not they had made it). The next move number is considered to be 45 (need to complete move 60 before the next flag).
15F. Reconstruction after time control.
After the end of a time control, if the next control is not sudden-death, each player must make all efforts to fill in any missing moves on that player’s scoresheet.
15F1. Reconstruction of scoresheet by one player.
After the completion of a time control, a player who alone has to complete the scoresheet must do so before making another move, and with that player’s clock running if the opponent has made a move. An additional set and board may be used.
15F2. Reconstruction of scoresheets by both players.
After the completion of a time control, if both players need to complete their scoresheets, the clocks should be stopped until they are completed. Additional chess sets and boards may be used. This does not apply if the director rules that it is unnecessary. See also 15F4, Reconstruction when the next time control is sudden death.
15F3. Reconstruction impossible or unnecessary.
If it is impossible or unnecessary to reconstruct the moves as prescribed above, the game shall continue. The players should make a clear diagram of the position reached, and the next move played will be considered the first one of the following time control unless the players agree that a later move number has been reached.
