My experience is that lesser players who think a finesse is working routinely take it again immediately.Definitely agree with that. It's clear you can't say "declarer gets the rest because he will run his winners before taking the finesse again and find out west is squeezed." If we do that we might as well employ gib to make all rulings. Definitely agree with everyone who thinks that when you have claimed on the basis of finessing, you don't get to cash out non-spades as well. But then I didn't intend to suggest that. This is an invented example, and my opinion was that it wasn't a great example, because I don't think it is realistic. Just an opinion. If others like the fact that the claimant can end up with 11 or 13 tricks and find it instructive, that's fine.

Not a great example, since even most lesser players might cash their winners after the two spades and all would be clear.

Would they have falsecarded if North had A10xx, or they couldn't see North's hand.

A final thought. If the Director judges that the most likely interpretation was a mental blind spot on declarer's part, where he thinks he can cash out - then declarer pays a heavy price for carelessness in the play or in his claim. As Director I would feel very uncomfortable in that situation if West then showed me his expert Jack of Hearts. I don't see how I could change my judgement to give West what he might well deserve.

I'd assume that playing toward Q9x expected to gain from the psychological pressure on East, rather than being ignorant of the obvious double finesse.

Declarer has, of course, been extremely unwise - demonstrated by the fact that he would have lost his slam (subject to appeal!) if several of the posters were the TD called. I would take the view that the repeat of the finesse is implied in his statement and that 70E1 does not apply. I don't think, by the way, that weak players finesse the nine in this position.

If opponents bid badly and make a low percentage contract, I don't see the role of the TD.

It seems reasonable that responder can choose his escape from 1NT doubled -planning to play in 2D undoubled or convert to 2H if doubled. I would poll peers, to be sure. It would also be good to confirm what peers would do if opener alerted, explained transfer and then passed. But it would be hard to ask that in a non-obvious way.
