West's jump to 6
shows a void in clubs and two or more keycards.
East knows the keycards must be the
A and the
A which is 8 HCP,
and West must have at least 3 more points outside of clubs.

The 5
response tells East that his partner has two keycards,
but not the queen of trump. With a missing keycard, East settles at the small slam.

East's first response could be one of several, depending on the partnership's methods.
Some players would simply show a limit raise by jumping to 3
while an aggressive
partner would splinter in spades. And still another might use Bergen and jump to
3
or 3
depending on which one shows a limit raise.
Any of these bids could induce opener to check for aces.
East's 6
response shows a void in spades and two or more keycards.
West bids seven with confidence!

The 5
response tells East that his partner has only one keycard,
so it's time to stop.
Of course, it's going to make seven without a club lead, but you might not want to
take that chance.

Bidding 5
shows two keycards, but missing the queen of trump.
You will most likely have to lose to the
A and perhaps the
Q.
Nobody would fault East for quitting after deciding it's not enough for a slam.

In the auction above, East initiates the Major Suit Keycard sequence,
but either side
might decide to make a slam try.
East Asks -
Note that the 5
bid, which shows two keycards with the
queen of trump, allows the
partnership to stop immediately because they knowing they are off two keycards.
West would have to bid 5
playing Roman Keycard
and commit the partnership to slam.
West Asks -
The auction would go like this if West decides to ask for aces:

West |
East |

2NT |
|
4NT |
5 |
In this auction East bids 5
telling his partner
that he has zero or one keycard. East will stop.
