2§ = The singleton in West's suit, the lack
of aces, and probably wasted values in spades should keep East from rebidding 3§ (or even 2NT).
2¨ = Preference, since 5-2 fit in diamonds will
probably play better than a 4-3 fit in clubs.
2NT = The right call at the right moment. West may still have 8-9 hcp.
Another piece of evidence that responder should not pass too soon on opener's first rebid.

4ª = Preemptive, promising a good, but not a
solid 8-card suit.
Dbl = An overcall of 5§ would give up on the ©-fit, and slam as well. West would bid 5§ without the ace of spades already.
5ª = Asking West to pick a suit at the 6-level.
6© = East would have bid 4NT with length in
minors only. If West has the same sort of hand with an extra king, he will reach for grand
slam.

2NT = In our system: 6+ spades, less than 3 hearts, no 4-card minor worth mentioning,
and 12+ hcp. We use the 2ª-response as Garozzo
splinter, i.e., 4+ hearts, some singleton, and either 8-11 or
16+ hcp. West must alert this 2NT-response, of course.
3ª = Designates spades as trumps.
4§ = First or second round control of clubs.
4¨ = First or second round control of diamonds.
4ª = Waiting bid, denies first or second round
control of hearts.
4NT = RKCB for spades.
5ª = 2 or 5 out of 5 aces, plus queen of
trumps. East shows the queen of trumps on the knowledge, that EW have at least 10 spades
between them. If the queen of trumps belongs to NS, East has at least a 90% chance to pick
up the trump suit withou losing a trick.
With 2 of the 5 aces missing, 6ª is a 50% bet
at best, so West knocks it off.
