(Ton) It must be my incompetence of understanding English, which is told to
me by
a lot of people explaining why they feel to be right.
But my knowledge of mathematics/logic is still such that I think that the
statements by Wayne above don't make sense. How can one say that an ace is a
subset of HCS, but being special cannot be considered to show strength as
such?
 
# I'll have a shot at it - not that I agree with Ton, BTW.
 
If your 1S opening shows 4+ (or 5+), don't alert it.
If your 1S opening shows 4+, but not 5 (possible when using Canapé), some SO
s say you've to alert it.
If your 1S opening shows 4+ and denies 4+ hearts (Swedish two-step), you've
to alert it.
 
If your 1NT opening shows a balanced 15-17 (or anything), it isn't alertable

If it shows a balanced 15-17 with 4 spades, it is.
 
So, sometimes, a subset of a non-alertable set is alertable.
This means that it isn't absurd to say that an Ace-showing cue (subset of
strength-showing) is alertable. BTW, I've seen written that ace-showing
responses to 2C openings should be alerted, because if one doesn't  they
could be taken as length-showing (which can't be said of the case under
discussion).
 
In our case, it isn't that 5H doesn't show strength, it is that it doesn't
show "strength".
Credit that to Chomsky.
 
Best regards,
 
   Alain.
