Most likely the answer is fake anyways. Secondly when the answer is "Korea" its a mindgame from the start. You will think that the guy is gosu and you have no chance anyway. Just play like you would play any opponent and enjoy the game and try to concentrate and win.
2) Don't play all-in all the time -> Reason:
iCCup is your chance to try out strategies. Obviously you can practice all-in too since every good player most likely has a all-in move which he can pull, but not all the time. I'm not trying to "remove" cheesers / all-in users with this, but you will most likely gain a lot of experience if you practice builds you can always use. For example: My 1 Fact / 1 Port is really weak and I train it on iCCup with a smurf-ID, because no one will look at my stats, but I gain experience.
3) If you are emotional, you should smurf -> Reason:
There are always people who will look at your stats and trashtalk you when you "only" hit B with like 80-40, because they don't realise that its not stats that make you good. For example a German player "ash.Kolll" has, as it seems a lot of time on his hands and played ~800 games last season. He's on 300 now. He won against Clon (Airforce ACE) and he beat Phoenix66 2-0. Now thats what you get from experience.
