Discussion about R15,R17,Q17,Q18,P17

At position R15,R17,Q17,Q18,P17, @wy20305 started the conversation:

I think we discussed this on the forum once before, possibly before OJE even existed…

I think the linked position has everything moved one line to the right. 1 is at a 3-5 point rather than a 4-5 point.
