Well, One thing I think of about blinds, they are not my chips. You do not need to defend your blinds. I used to defend my blinds like crazy, until i noticed it was just hurting me. Now I give them up unless I have a hand I feel like playing, or feel like outplaying someone. I never need a great hand, just need to be in the mood to play back at someone. Just remember, the chips from the blinds are not yours, it is the pots. So it isn't definding your blinds, casue those blinds are not yours.
