Question for David Sklansky or other probability/poker theory experts

It sounds to me a bit like you weren't trying much to feel out what he had on each hand. I realize this is very difficult to do, especially online, but if you don't know what you're betting into, how do you know you're making the right play?
You can generalize and say that on average making this play is correct, but it doesn't allow for you to adjust per hand.
