i am heading to 7h the only thing standing in my way is 7n and since this is mp there is no harm exploring.

if i trust my p

3h 4c (forcing)
over 4d/h/s 4n key card for clubs
if instead p bids 4n/5c 5d key card for clubs
after getting zero from p i then ask for trump Q
if yes i bid 7n if no i bid 7h

If i am unsure how much to trust p i will just bid 7h.

this type of planning comes up quite frequently when your eventual trump suit is
above a suit u have a problem with.
