Default Heads Up SNG standard D

If standard deviation is 6.9 in 10+1 buy-in heads up SNG (60% ITM), what is the risk of ruin and minimum bankroll requirement?

You need to account for EV in there.
Then fire up google, and look for kelly betting.

Kelly% = .13

What's the BR requirement given this and the other info I've given in this thread?

60% win% + 10% vig tells you the ev.

Kelly doesn't work here since we can't adjust the buyin amount.

Kelly still "works", improvising poker players have been using it for years. Bill Chin even wrote an article for the 2+2 mag on the topic not too long ago.

Look for the Sileo/Chen/Weideman/mel3brown formula. BruceZ has mentioned it several times, and even posted his derivation here some time ago.

You need about 183 buy-ins if you win .6 buy-ins per tournament. Your risk tolerance pegs you at about .4 Kelly.
The formulas are old and were discovered by the blackjack theory people in the 90's. See our paper at bjmath.com. Copies of my 2+2 mag article are available on request.
