I am most comfortable with ICM and how it changes your strategy in sit and go's and in spite of playing a ton of 180's lately I haven't really studied them with regards to icm. Can you guys draw some similarities with how much tighter your calling ranges have to be as the bubble approaches in 180's and sng's?
For instance something like " calling ranges when 5 handed in an sng are very close to calling ranges with 40 people left" would be helpful.

I guess I always believed that bubble factors were less important in bigger fields but i guess I don't have a well thought out reason as to why.

Pretty much ignore the bbl in 180s, if anything shove wider cos ppl will call too tight. And in all but the extreme situations you can basically ignore ICM til its 5 handed or less.

(consider how top heavy the payouts are in comparison to 9mans)

So is it just Cev in all cases till the bubble?

Till the final table.

Abuse all bubbles.

The ranges are veeery wide in 180s right? I am just coming from 9man SNGs with $EV so it looks like spew

I think its ok to abuse the bubble with the right stack sizes. I wouldnt suggest jamming a 25 bb stack into someone who has you covered with any two cards just because its on the bubble.

Basically, in 180 mans I wouldn't worry about the bubble and play as you normally would.

Final table strategy is a whole new strategy when it comes to ICM.
