I definitely agree with most posted above. I am pushing KK every time in a tournament as long as I am not next to the bubble. With 70/30 those are good enough odds to double your stack. It may seem like it happens to you every time but it is probably not the case. I would not be upset at all to lose KK to A rag. If you are rely that concerned you can always raise like 4.5BB pre and shove on the flop. As long as there is not A.
