I asked in IRC, "What would you like the next quiz to be about?" Someone replied, "Pot odds."

I know what you're trying to say here, but you're a little off. The part in the bold is the reason you're a little off.

Correct for the case that the $10 puts us all-in. That leaves some other cases, though.

Another case is when implied odds are going to be the deciding factor, and everything after this line describes the types of things that affect implied odds (one or more of which you described incorrectly). But there's a third case which you and killerkebab have barely touched on but haven't described in detail.

This is an example of the fourth case I thought of. For what it's worth, I only came up with 4 cases.

You could argue this is an example of a 5th case that isn't always available.

This is key to a complete answer.
