I have been grinding Fifty50'es ($15 and $30) at Stars for quite some time now and was wondering about the calling ranges on, or close to the bubble.
Let's assume that a villain has the tendency to push any two cards from the SB, or a somewhat better range from any position. What should my calling ranges be?
Assuming:
1 - I am an below average stack with one or two more people having the same stack sizes as me, with six or seven players left.
2 - I am by far the bigstack and could easily lose two all-in's and still be able to continue in relative safety.
I am usually ahead at least by 60/40 against their ranges with any ace, and even lesser hands. But how does the payout structure affect the profitability of calling them? Is it worth to gain those extra chips, which convert directly into hard money [or not that hard, if dealing with $, (or € for that matter)], at the risk of losing the buy-in, as that part of the payout is not dependent of the amount of chips one holds when the sixth player busts.
Has anybody done the maths behind this? 
I'd really appreciate more insight to this topic.
