on the bubble

We are in the middle of the table,
play aggressive stealing blinds
or
play slow and wait for elimination of a player

We need a little more info. Stack sizes for you and the table. Your image. The image of the rest of the table. Absent allot that I will just give you some general advice. Pick on medium stacks. Short stacks are too desperate to mess with and you will have the odds to call too often. Lose a couple of those and you will be the short stack. Big stacks will put you to tough decisions so avoid them. Plus if you guess wrong against a bigger stack you're out. As for medium stacks, pick on those who are too tight or give up when they miss. Never sit back on the bubble. The bubble is where players pick up chips.

I'd pick 2nd option but yeah it depends a lot on the tabld you're playing on and if you're chip leader you can boss around more since they won't want to lose all theid chips because of a stupid move

on the bubble? that´s it?

friend, in order to get a good feedback, need to give some of them:

stacks, positions, fields, prizes, buyin, 6-max or full ring? blinds, time structure, etc, then we can add something, but just bubble is not enough

Bigstack - play aggressive
Midstack - wait for the bubble to pop or play only primo hands
Shorty - if you can make the bubble pop then fold everything... if will not make it because of blinds, start shoving and A K Q!

play bubble primo hands, because short shacks have to push EQ hands like KQ, etc and if you will open a lot of hands playing aggresive is "-", aggresive playing will give you more in itm if you will save good stack on bubble

What's your goal, if your goal is to win hit the blinds hard from the button especially if you can cripel or kill them,If your so short stacked ,you can't win or in sattelite were everyone gets entry fold, a lot of factors really need more info.

If you are shortstacked I would suggest to wait. But if you have any stack whatsoever go ahead, play aggressive, steal blinds when people play tight to get into the money. Accumulate chips and aim for the first prize, not for the last. The only time I would settle for waiting a few people to get knocked out is when I would be shortstacked and I feel like getting atleast my buy-in back.

If you're short stacks in the tournament you might as well get your money in good. Try to double up! If you have a legitimate hand.

Like others have said we need more info.
But when the bubble is upon me and I've a healthy stack I like to be the agressor and steal the blinds from the shorter stacks and really put the pressure on them

play slow and wait for elimination of a player, I always waiting for prizes, cause im not agressive too much to steal blinds with nothing
