On BBO, non-regular partner, opp are regular pair and strong
I led a small spade to SA, partner led back a C to my A. After that I returned a club so declare's spade loser went away on ♥AK and because of my double declare knew how to play trump. 5♦X make
partner:"very bad double p."
Frank: "Yes but I prefer SK at first trick."
partner:"and I prefer you to lead SQ."
Frank: "Yes"
Question
1. If I pass 5D is that forcing?
2. Any other comments on defense and bidding are welcome
