The Kelly system tells you when to stop.
And I stand by my claim that:
"With the Kelly system there is zero chance of going broke, and a very reduced risk of bankroll depletion."

You know, rather than admit that your "correction" of Jean was an overstatement, you want to invoke "stop-loss" and "gambling addiction"?!
You initially wrote this:
"Jean wrote: "There is never a zero chance of going broke."

That's simply not true. Now you seem to want to amend it by saying the player should stop before going broke.
Yes, we can all agree on the obvious: The only way to eliminate the finite chance of going broke is to stop playing. In contrast to what you wrote initially, betting Kelly does not change that.

Your advice on Kelly betting is solid; I enjoy reading your posts, particularly the ones about Kelly and "NO".

You would never bust out, but you might have to quit gambling and go back to work at some point. By using the Kelly system to define your stop limits, you would be optimizing bankroll growth, for the bet sizes you have available.

In the case of FPDW you might have a choice of $2.50, $1.25, $.50, $.25. One of those sizes is more Kelly optimal than the rest for a given bankroll. Multicoin and Multiplay games often provide even more choices of bet size, though not very often for FPDW.

Well, not exactly. The Kelly system does promise a zero chance of going broke, but only if you can continually resize your bets downward if you start to lose. Betting strictly according to the Kelly system requires a re-sizing of bets after every change in bankroll size, even down to fractions of a penny bets if you run particularly bad. (All of this assumes you have an advantage. The Kelly bet size for a negative expectation bet is $0.)
In the real world, this kind of bet re-sizing just isn't possible, particularly with VP. If you start out with some fixed amount of money, *and you maintain a fixed bet level*, you definitely have a non-zero chance of going broke, no matter how much money you start out with.
On the positive side, if you start out with a large enough bankroll relative to bet size, and a strong enough advantage, then we might be able to say your chance of going broke is "just about impossible", even if you can't re-size bets downward.
