Ignore the bidding where I had chosen to open 1NT with a stiff King, and was trying to wriggle into three notrump after the transfer
Lead was D4 to the Q and King
I played C9 to the J and Ace, and returned the C4 to the Q and King.
Now west needed to play a Heart but he did not know that on the bidding.
He played DJ, I won, unblocked HK and exited D5, pitching H, (my D9 set up)
Now east was without resource. He tried a club, but instead of running it round to dummy (obvious and wrong) I rose and played three clubs and the established diamond, putting pressure on West in the delayed duck department, in spades and heaarts, he came down to S:AQ H:Q in the three card ending
I pitched all my hearts and one spade and when I played up a spade, West won, and had to give me a Heart stepping stone.
