Good question. I might pick up on the fact that someone was exuding something they didn't really feel, but that would indeed be the best way to thwart my detector (trying to really believe you have a good hand when you don't).
I can tell you that I joined a poker tournament once at a company picnic and I had almost no idea how to play poker, I didn't know what hands beat what, and somehow I beat 50 other people playing poker. It finally came down to just two of us and we were pretty much stalemated and it was getting late so we picked one card and highest card took home the prize money (I lost). So all I'm saying is... don't test me boy!
hahahah
