Every man and his dog knows you steal blinds with a weak range from CO & BT & SB in today's games at least on pokerstars now. It made me a sad panda when 11/8 nits start 3-betting vs my SB or BT raise. Weak tight FT tables will vanish in the foreseeable future imo and 3 betting/ 4 betting seems to become the new trend lately between regulars So the best you can do is probably adjust yourself to any table dynamics, game flow, players' tendencies,etc.
