Shania is always important IMO, regardless of stakes.

Usually when forming a range you tipically start by adding hands that are +EV "alone". Then you keep adding hands that may very well not be +EV on their own, but add to the EV of the whole range. That is basic Shania concept. At 5NL, where people arent paying too much attention, adding hands that are -EV to a range for balance reasons will probably be -EV for the range as a whole. However, the important thing to keep in mind, is that when adding a hand to a range, the effect on the EV of the whole range goes beyond the EV of that particular hand. In this example, AQ is a hand that probably is +EV itself to open UTG, but it ALSO makes other hands in that range more profitable, having a ++EV effect.

I could be way off here, but thats what I was thinking about when I mentioned shania.
