No alerts were made on the bidding, and no questions asked. West led ♥8, East playing the King. Wich resulted on 13 tricks for declarer.

East summoned director and claimed that partner would never lead a heart had she know that north had shortness there.

Director asked south why didn't alert 4♥ and south explains that they have agreed on splinters showing opening values, but no agreements for passed hand splinters were made. He also explains that his lenght in hearts had played a major role interpreting partner's 4♥ bid, more than their agreements. No convention card is shown.

North says that if he wasn't a passed hand he wouldn't bid 4♥ afraid of missunderstanding, but as a passed hand it made no sense for 4♥ to be natural so partner would deduce it.

When director asks west what would she lead had 4♥ been alerted, She hesitates and says perhaps a diamond or a club.

[blackshoe]

Uh, huh. Sure.

Does East not think West can speak for herself?

[menggq]

If N/S play DRURY may reach a ♠ slam contract and get better scores without any trouble.Any unnormal bids sd be alerted for sure.
2 WAY-DRURY is workable for pass hand to respond one major bidding by PD:
p p 1S P
?
2C=3 card spade support inv hand
2D=4 caed spade support inv hand

Unless they'd specifically agreed that splinters were OFF by a passed hand, I think the default assumption would be that they're on. And South's inference from his heart holding merely confirmed this assumption, so he should have alerted.

On the other hand, West can also figure out that it's unlikely that North can have a hand worth bidding 4♥ natural when he couldn't preempt on the first round.

And if North really does have a boatload of hearts, how did that make the heart lead attractive?

So while there was an infraction, I don't think it caused the damage.

Presumably this was played somewhere where 4-level responses are alertable.

[Fluffy]

yes, 4 level responses are alertable, also splinters are pretty much standard althou 1♠-4♥ might be an exception for about 30% players.

[Cyberyeti]

The heart lead is absurd whether a boatload of hearts or a singleton has been shown, playing the K has also done damage here, although I suppose leader could have had Q108.

I can't imagine a hand with hearts only that would have bid 4♥ having failed to open, although a fit-jump type hand would be possible (same hand with red suits reversed), but I'm not sure this makes the lead any more attractive. I would certainly have asked about 4♥ at the table as I don't consider straight natural as an option here.

No damage done, result stands.

[Rossoneri]

Sure, there has been MI, but either way I don't see how EW have been damaged by NS, rather than by their own actions.

Table Result stands.
