well there bubble play can be complicated.
If you are a large stack, figure out who is trying to make the money and attack them relentlessly.
If you are medium stack, figure out who the LAGs are and 3bet, 4bet shove them. They've got 15-30bbs, most likely they are not wanting to burst.
10-15 bbs, you still have a little fold
equity. pick a hand that you are willing to go to war with whether it be suited connectors AJ+ and pile it in their face. Warning, do not 3bet calling stations . Lay down AJ- and even JJ- They are content just getting it in and see what happens. Attack the nits and the rocks.
Whatever size stack you have, think about what will your opponent most likely do with his/her range.
You have a 10-15 bb stack, and more than double it on the bubble with aggressive play and selecting the right spots. Start applying the pressure when there before you hit the literal bubble. When it's down to 10, 15, even 30 people.
Just my thoughts. Gripsed has some great advice and videos on bubble play and yes, I stole them.
