I guess its a tough choice.

Looking back the main reason that I folded was because his VP$P was so high even though I had only seem him play for 9 hands. Therefore I guess it was very possible for him to have weird stuff like A4 or even slow playing Aces or Kings. That added to the threat of a set... And yeah the weaker bet probably set myself up for him to make a move like that so that was bad. I told myself I wanted to feign weakness to get callers or even a stupid raise, but I have to be careful what I wish for!
