This agreement seems to be consistant with many (but not all) of the posts. But why so? Is there some compelling logic that I'm missing! I get the idea of retuning high/low from original holding of 3 if unblocking or pinning is a consideration, but what if it's not? Another consideration is what to lead from XX, does it not make sense to lead low if playing upside down count. Ofcourse if your leading from Hx, the honor would still be lead.
