How much would you bet?

[tech]

Here are two decisions I had to make in the last few days. I am interested in other opinions. What percentage of your bankroll would you have bet in the following scenarios? I know the "theoretical" answer from an EV perspective, but I am interested in the practical answer of how much you would actually bet. That might or might not be the same as your theoretically max EV.

(1) You find a scalp opportunity where you can earn a 10% return on money wagered. The bets cash in one month. So this is essentially a risk-free 10% return in one month.

(2) You find a prop priced at -1000. You know that this prop should be priced at -10000, at a minimum. Again, the bet expires in one month. So here you have a 10% return in one month with the risk of losing your capital being 1% or less.

In the first case, how low would the return have to be for you to think you might miss other opportunities that come along?

In the second case, how high would the risk-of-ruin have to be for you not to bet your entire roll?
