Let's suppose that we are playing full-ring NLHE. We are properly rolled, but only for exactly the max buy-in. Several players at the table have more than the max buy-in, so when we win, our buy-in + our winnings will be exposed to risk as soon as we stay at the table. Is there a standard answer for the stack size we should not be willing to play (if covered)? Is it 2xBI?

Extra credit: now suppose we're rolled for a 150 BB buy-in but the max is 300 BB. Does the answer, as a function of our original BI, change?
