if im short stacked I never slow my play down but I will fold a lot when close to the bubble just to try and make the money..seems that with online poker if your short stack and go all in at the bubble that all a big stack has to do is call with any 2 and they will end up winning the hand....if im mid to big stack ill play regular or get a little more aggressive...ppl tend to play less hands when close to the bubble so sometimes you can do a lot of blind stealing
