I'd like to hear real examples of this ruling being applied because it seems to me that it would be extremely difficult to enforce. There is a limit to moves you can make, barring repeated searrching of discard, shuffling at length, etc. Are you going to be able to look at a game and say to a player "you have a watch, you know there is less than 1 minute left in play, prizes are tied. You played SUU, POV, then Cosmic Power, before KOing the Pokemon after time so your opponent wouldn't get a turn, didn't you?" Thats making a lot of assumptions. Then when the player says, "no, I thought we were going to go into Sudden Death and I wanted to improve my game position", what are you going to say? I'd much rather allow judges to grant discretionary 5 min game extensions for "ambiguous wins". No one should win a game they otherwise would have lost because their opponent didn't get 1 more turn. One could also adjudicate games that go to time, based upon the entire game state, rather than going just by the prize count, but that would require a level of playing acumen that most judges probably have, but none are actually required to have.
