Equally if you take away the heart ace from west’s hand he will still have a 2C bid but 5C stands no chance whilst 4S needs just a trump break. Perhaps after the sequence 1S - 2C - 4C a bid of 4S should be non forcing.


And he bids 4, of course it's NF

Over this the auction continues 4-4(showing a diamond control as well as partner's denied one)-4N and if partner only shows 1 you sign off in 5 and hope you can make it


We play that after 4-4 the 4N by West shows an even number of Keycards, so East can now sign off in 6 with near certainty that they lack 1.
Knowing the number of Keycards below 5m level (and without interrupting the control-bid sequence) takes a lot of the luck out of reaching slam.
