I once saw this question posed on this site: If you had everything you owned on a poker table... everything, your house, your business, your car... etc. and you were playing heads up against a guy, he goes all-in and has you covered, and you look down at AA would you call?

I would, it would take me about 1/100 of a second to call, but I have gambled a lot bigger with a lot less edge at life situations. So I don't really mind not knowing my opponent if I am guaranteed not to be behind.

So sure it is good to know your opponent, but it isn't necessary. You can still make the best decision based on the information you have.

Now, in the same situation, if I knew this guy only puts everything in with AA, I would fold. The 9% of the time that he flushes, would rip me apart inside.

So obviously it is best to have as much information as possible.

I don't think way over betting the pot with AA is the right decision. However, in hind site I think it would have been way better.
