Non-vuln against vuln, first seat opening.
As others have written, one deal proves nothing. Still, I think 1S
would have been better than 4S at this vulnerability.
One exercise I find helpful is to decide how high I would preempt if I
decided to preempt. The hand above is worth 7-8 tricks in spades, so if
I preempted at these colors, it would be 5S or 6S. Even 5S seems too
much, so 1S it is. (There are people who would pass and see what
happens, but I'm not one of them.)
If the colors were reversed, opener's hand would be in range for a 4S
preempt. You might decide to open it 1S anyway, either because of the
defense or for tactical reasons, but 4S would at least let responder
compete to the proper level.
I do not understand why your exercise is helpful.
The main idea behind preempting is to stop opponents finding a good
contract higher than your preempt while your risk going for a number
should be limited.
Of course sometimes you will preempt your partner.
But the problem was not that you did not reach slam. The slam is not
easy to reach and it seems few were in slam after opening 1S.
Opening 1S will usually make it much more likely that opponents find their best contract.
So it is rather unlucky that North South found their club fit at the 5
level and sacrificed red versus white at the 6 level, while most North
South reasonably did not compete at this level.
Just look with what South bid 5C, vulnerable to boot.
I doubt this would happen at a high level game.
If it did, then partner would bid the obvious 6S over 6C and consider
bidding 7S over 7C, and consider how to get the opponents to play 7H
wrongsided instead of 7C and making a Lightner double of 7H.
Partner has KQJ xxx KQJxxxx void. This needs opener to have only
xxxxxxxx xxx x x for 7SX to be a good sacrifice against 6C (especially
at matchpoints) (it is down only 5) or Axxxxxx xx xx xx for 7SX to be
a good sacrifice against 5C (especially at matchpoints) (it is down
only 3 unless the opponents have a diamond ruff and find it).
At matchpoints, the weakness of the field must be considered. Even the
likely down 1 or 2 in 6SX is bad if a not very large fraction of the field
play in 4SX or 5SX making or down 1 less than 6SX. But if the the opponents
bid 6C or 7C at this vulnerability, then I would believe them with partner's
hand. This hand has half of a defensive trick and the bidding indicates
that partner is on the light side of having 0 defensive tricks and the
opponents have their bids, so 6C will make easily and the problem is what
to do over 7C. I would believe that 7C shows that they have first round
spade control but that 7C is down on a due to having a diamond or heart
loser or just be psyching 7C with a spade loser.
Partner's 5S bid must show something. It should't be bid to transfer the
opponents to 6C when that is a good spot or to go down many in 5S. Partner
might know what to do over 6C or want cooperation from opener. It is very
easy to cooperate with 2 aces. Doubling seems obvious. The 2 aces give
defense to 7C, so opener knows that the choice is between 6CX and 6S, with
6S very unlikely to make. Hopefully responder will rememeber that he knew
what to do over 6C -- it is to bid 6S -- and not pass 6CX. The double also
solves responder's problem of what to do over 7C -- just double it and
hope to beat it 2 to protect the cold 5S.
