should we be taking more chances?

This is the part where I have the most trouble in any mtt I play in, right now as I type this i'm currently chip leader in a 2.20 mtt on stars but can't figure out weather to be more dominate and force the blinds to have an actual hand against me (So I could steal more blinds), not to mention it's nearing the bubble or if I should stay with my one approach which was play tight aggressive and only premo hands?
What do you all think is the best approach this late in a mtt or tourney?

if you have been at the table awhile, you should have a read on them. Push your stack at the tight players that are on the bubble. tighten up against the loose calling stations.

and remember position position position, watch out for unwanted action, dont play trash and make them pay to see when you have the cards to bet

If I am in that position I try watch my position and make players pay for the cards. To many times I have limped into hand that I could have won if I had only raised it preflop and instead, I lose it altogether. You know that short stakes close to the bubble will only be playing Ace, X or any pairs. So just pay attention.

Chip leader at the bubble! holy crap you are golden man, you should stay up dreaming about these situations...

steal. steal, and steal!!

now is the time to start bullying pots, moving in on weak opponents and trying to build as much of a lead as possible

this part of the tourney is when most people start to play very tight/weak and are afraid of clashing with the chipleader. Your stack is your best friend, you can use it to threaten someone with getting knocked out 3 spots before the money and alot (ALOT) of people are so scared of that, that they wont call you down with less than the nuts.

ya I figured as much that's what I kept on doing made it to the final table but then I don't know the aggression level just would'nt quit in me yet and went from first to 6th in a matter of 10 hands, lol
