River calls and magic carpets
Here's one that seems relevant given the battle of the youtubers last week. If you find yourself on the river in the worst of all spots, holding something in middle against a polarized range, how do you decide which hands to call and which hands to fold? What are your metrics? Do you know your ranges well enough to decide what is the best X% to call with and where your actual hand falls right now? Be honest. Are you guessing? If you believe that your opponent is overbluffing but just slightly, would you call with your entire set of bluff catchers? If not, why not?
