The bubble is not a big deal. Just fold your very bottom from your range. You most likely need 2-6% more
equity. Play tight. But not very tight. You can do the same things, but with less
hands. A little bit less..
If your have a mid stack, stay away from other mid stacks and the chipleader. Avoid All in situations without very strong hand. Avoid postflop confrontation with borderline equity. Play "small ball" against them. If they are pretty crazy, just wait for good hand or for the end of the bubble.
If you are a chipleader , play aggro, but do not go crazy. The ICM is also for you. But smaller factor.
The "tanking" is a good thing. Do it!
But if you have a big stack, no aggro big stacks on your table, then play normal.
