It is a somewhat hard decision in a newbie tournament. As long as he didn't get any important information by attacking, you could also decide to load the game and correct the mistake. Mistakes happen, an instant loss is a high price.
About the red-rush, I received a message from a stream viewer. Jelen finished his turn even without remembering about this rule. He had enough time to think; they were playing with the 1.38 HW_rules patch, which reminds them every week "don't forget about red-rush."
Considering all that, it could be a win with a flagrant violation of the rules.
That's why I made this decision.
