I led ♠K asking for unblock, partner unblocking ♠J (forced to unblock even if he has 4 spades), this is debatable, but it is of no interest for the purposes of this thread. declarer ducked playing the ♠6. I played ♠Q back, partner playing the 9 and declarer the 8.
More spades are useless at IMPs, so I switched to hearts.
The question is, playing 3/5 attitude, shoud I switch to ♥5 or ♥4?
I never know if I should show attitude (lowest heart promising a honnor), or count (third heart since we play 3/5 now). If I had 3 small it is obvious I would switch to highest one, but with 4 cards I never know if the 3rd or the 4th is the correct one.
From the other position, when opening a suit through declarer where dummy has 2 or 3 small I lead lowest form 4 to a honnor, but when dummy has a honnor I have more doubts.
There are times where you have a honnor but want a switch so lead highest pip, this is unrelated to what I am asking
