I ran into this 2x over the weekend.
In 1 tournament, I got coolered with flush over flush. So as the bubble approached I just had to nit up. Playing only super premiums. I did not have enough chips to get anyone to fold Ax or PP. After the bubble, I went on a heater and was starting to accumulate chips. Unfortunately, I got donked off by a chip leader but it's alright. If you have between 4-10 BBs on the bubble, I would rock up. If you're sitting on more than 10, you can use your push/fold strategy. If you have 20 or more BBs, then look for the people that are rocks. Rob them, rob them, rob them. If one of these rocks plays back, fold anything but AA or KK and maybe all the way down to AQ if you don't mind flipping. If there is a bully at the table, catch something you want to battle with and jam him. Show them once or twice you're willing to take a chunk out of their stack given the opportunity.
The other tourney I was sitting on around 40-50 BBs and was able to steal blinds at will. I did run into a cooler. flopped a straight and get shoved on. guy hits runner runner for a boat. However during this time, I was able to raise into other medium sized stacks as well as 20-30 BBs. Just 2.5x raise and fold if they play back. You're going to get more blinds than you are going to lose. Don't go crazy with the steals but play enough to keep stacking up.
