I was on google trying to find out whether it was correct or not to call a bet when you have a flush draw, and I landed on one of Tyson's essays, I think the pot odds one.

As you can see, I was as green as they come when I landed on FTR. I had never heard the phrase "pot odds" before. I had just put $50 into party poker a few days before and I was playing the 0.50/1.00 limit tables, just going on "instinct". I had no clue about any poker theory whatsoever, but I knew some theory must have existed and I wanted to learn about it. FTR basically taught me everything I know.
