Another UI case LA or not

You open 4♥, LHO bids 4♠, partner passes slowly, pass to you, is pass a LA ? 5♥ is -1.
Also if you decide to adjust, 4♠ is not an automatic make. Presumably you can adjust to say 70% 4♠=/30% 4♠-1. How much benefit of the doubt do you give to the NoS in this situation.

Pass is definitely an LA. Preempters normally don't bid again anyway - and after a slow pass really cannot to my mind. I don't see the 9th heart as much defence - I've seen people open 5♥ in the first place with that sort of hand - so it isn't as if it wasn't an option in the first place.
Admitedly I've seen many preempters bid again when they shouldn't - but no matter how inexperienced, IMO, they really should learn that a slow pass from partner does constrain them.
I'll leave others to answer the other question.

P.S. I've seen people open that sort of thing 2H (strong) many times too - much to Bluejak's consternation - and partner's when they double opps high level contract.

But when I have nine solid hearts and a singleton spade, my first thought is that partner is considering doubling. So I'm not convinced that 5♥ is suggested by the UI. But I may be in the minority as, interestingly, in a different case currently on bridgewinners, quite a number of posters are certain that slow passes in this situation always show offence, not defence.

Some people open 5M as a slam try. At least they used to; I am not sure how popular that approach is now.

I've seen plenty of people play a free bid of 5M in the middle of auction as a slam try expressing that trump quality is the primary concern. I can't say I've seen anyone play that as an opening bid, though.

As to the weighting, you decide what you think the likelihood is of making nine or ten tricks in spades dependent on your judgement and that of the people with whom you consult. Having decided, perhaps, that ten tricks will be made about two times in three, you then might give a small benefit of doubt swing, so rule something like
.. 70% of 4♠ =
+ 30% of 4♠ -1
Especially if you are unsure or the consultants disagree with each other a lot, you might make it 75%/25%. On the other hand if you think it will make ten tricks one time in three, then you might rule:
.. 35% of 4♠ =
+ 65% of 4♠ -1
or even 40%/60% as before.

And check if that outcome really benefits the NOP.

Obviously I didn't open 4♥ because I consider it the limit of what the hand is worth. I opened 4♥ in case we take exactly ten tricks and they make nothing and/or let us play there. That seems much less likely now.
I don't have to stop playing bridge and just accept a poor result any time partner thinks before passing.

I would also always bid again, and would know I was going to when I opted to bid 4♥ rather than 5.
I had no horse in this race, I was in the A team of a county match when our oppo did this in the B team. They volunteered that pass was an LA and conceded the adjustment to 4♠=. I thought that was generous although they were losing the match by the maximum regardless of the result on this board. The preempt sort of did its job, 6♣ is cold the other way.
Not sure what the slow pass was thinking about, hand was A8xx, xx, J9xx, J10x.

Sure they don't normally bid again but neither do they normally have nine solid.

I would be more inclined to roll back a 5♥ bid after a fast pass by pard than over a reasonable tank.

It was ruled - and I agreed with the ruling - that there was no LA to bidding 5H. This is in line with my usual rule for 'bidding again' rulings: if you have 2 cards more than you have shown, you usually bid.

Nor do I. Which is why I would bid 5H.

But I understand that there are LAs, too many posters said so.
But anyway- the only bid a slow pass would suggest is double, because that covers all bases, so where is the problem?
Or is a partner who is unable to decide whether to pass or double quicker then a partner who needs to decide between pass and 5 ♥?

since 4♠-1 is worse than 5♥-1 would it make sense to rule 4♠= 70% 5♥-1 30%? is this ilegal ruling? (in case we ruled that pass is a LA)

If, though, there was a legal way to get to 5H, as there sometimes is in these cases, then it can be part of an adjustment.
