i checked the demo and to be honest it might be just a luck
i already did the same exact move . cuz i saw a ct running to that corner and i shot wit awp in the same spot he he died
its just my opinion . lets see other people opinions
maybe a longer demo would have helped more
plus the smoke maybe he is using an antismoke . just maybe not sure
if its possible to record the same player again with a longer demo would be nice and helpful
