That is the question. It is not "What would you call with?" or "What variance can your bankroll allow you to sustain?"
To give an answer in any other terms hints at a possibly larger mental leak - not being able to focus. There are a handful of posters in this thread that have showed this inability to simply read a question and answer it.
The bonus question was: What's the worst hand you can call with in this situation.
My answer to that is AA. +EV is nice but playing 50.1/49.9 is a guaranteed route to bankruptcy due to variance. For example I just ran this on excel to illustrate. Using the "randbetween" function and set the range as 0-1. This give you a random 0 or 1 output. Run 250 times... Results
Trials 250
Heads 116
Tails 134
Longest Streak 9
In a pure 50/50, run it 250x and you could lose 9 buy-ins in row and overall 18 buy-ins. Running that trial multiple thousand times over and the net should fall to flat but that streak of 9 is going to repeat and I be willing to say jumps. So here is 1000x - not 250 trials 4 times just 1000 trials.
Trials 1000
Heads 538
Tails 462
Longest Streak 10
In this trial you still could be up/down a whooping 76 buy-ins! That is insane variance for a coin-flip. This is why I try avoid coin-flips which is what even optimal SC are in this spot. And I may be new here but I suppose this is why every thread that starts with "Is x BI enough for my bankroll" every response from an experienced player is you need x^2.
And because people may not believe that 76 number above which seems a bit high, here is 10,000 trials.
Trials 10,000
Heads 4,886
Tails 5,114
Longest Streak 13
So good luck on being profitable on coin flips - it comes down to that. Note we are closer to a 50/50 outcome (51% vs 49%) but the absolute number of possible BIs lost jumps which is what our bankroll cares about.
