What if the IS-2 hide with TrueSight?
Good players made mistake too, they are not god. Hans just lost his SU85 1hitKO on ice by his opponent's TA last week.
Or just quit this theory crafting bullshit in every trolling crap you posted?
If its hidden, its not attacking so no problem.
I've seen that game with Hans, everyone makes mistakes, Hans knew it was bad idea to drive over ice, he didnt made it in time out of it.
And my "theorycrafting" is based mainly on games played by players like Cataclaw, Hans, Stephen and others on their level. They aren't gods or magicians and still can pull things like that on regular basis. Yes, they also make mistakes sometimes, but that doesn't erase what they did.
