This immediately ends the game." However, the following relates to "quickplay finish" and may have been applicable: "Article 10: Quickplay Finish 10.1 A 'quickplay finish' is the last phase of a game, when all the remaining moves must be made in a limited time. 10.2 If the player, having the move, has less than two minutes left on his clock, he may claim a draw before his flag falls. He shall stop the clocks and summon the arbiter. a. If the arbiter agrees the opponent is making no effort to win the game by normal means, or that it is not possible to win by normal means, then he shall declare the game drawn. Otherwise he shall postpone his decision or reject the claim." In which case, chessbase would be correct.
