I would like a strategy that says:

- 2 if purine (R) (Guanine and Adenine) is to the right
- 1 if pyrimidine (Y) (Cytosine and Uracil) is to the right

Idea background [here](https://getsatisfaction.com/eternagame/topics/au_and_gu_orientation?rfm=1).

This is for multiloops, in case the closing base pair isn’t GC.
