2016 Winter Tournament: "Frozen Heart"

Dear Num, you’re getting on my nerves. I understand if this move had some significance. But you’re making a huge fuss over something trivial. And what about the fact that Bolivar crashed five times? Why do you call that move, which essentially meant nothing, cheating, but you consider it normal when someone crashes three times in a row?

I should have won immediately after he crashed. Why should I waste my time on him?
How can I know if my opponent repeated his moves? I generally hate these crashes.
