I'm really late to the party....
I am noticing here, danzasmack, that you are checking the autofold button in the small blind with weak hands (e.g. 54 at 7:18). Granted that there are going to be some hands that we aren't going to want to play even in a blind battle, but I am wondering about the possible information leak from autofolding.
I have been taking notes on players who autofold their blinds when the action is folded to the button. I think that it shows that their blinds are more easily stolen than average. It's especially noteworthy from the big blind (who ought to be prepared to play quite a lot of hands in blind battles), but I think it is significant from the small blind, too.
Likewise, I make a point not to autofold in the blinds, unless action early enough in the hand makes it clear that my holding just isn't playable, so as not to leak this tiny bit of information to players who may take note.
Is this something to which I should be continuing to pay attention? Or am I just being like those roulette players who track trends in how often Red or Black comes up?
