How To: Analyze Calling An All-in

I recognize that this is a stupid question, but then I am clearly not up on the knowledge like you guys, so here goes:

How do you determine someone's range if it isn't someone you've played with a whole lot, or its someone that just came to the table?

You just estimate it the best you can. You'll very rarely be able to know exactly what your opponent's range is with 100% certainty, and that's okay. With total unknowns, you can use certain clues like what their buy-in size was and what the typical players are like at that level. With semi-unknowns, you take whatever small bits of information you have and try to extrapolate.

In general just do the best you can each time and you'll naturally get better at it, even with very small amounts of information.
