I thought I'd post this one on this new and rather empty forum, some might already know the hand (it was given as a lead problem online at some point). As the case is now closed, here it is.

The hand was played with screens (N/E on one side)

Scoring: Teams


W N E S
-- -- 1♣ p
1♥ p 3♥* p
4♦* p 5♣* p
6♥ p p p

Opening lead: ♦K, N/S -980.

3♥ invitational, an unbalanced hand
4♦ West to South: Last train, East to North: ♦ shortness

Decision by TD: TD consulted E/W system script and found two chapters, according to which either might have applied, so he ruled MI. Furthermore, the TD consulted 7 players, who all would have led a ♠ given the explanation ♦ shortness, so decided to let score stand.

N/S appeal on the ground that with the correct explanation, it logically follows that ♠AK are missing, and that they also consulted 3 comparable players, two of which would lead ♦K.

Discuss.

Bonus question: Playing last train, logically this sequence means you'd bid it without a side control, as in the actual hand. Are you on firm ground in your partnership?

I agree with NS that an explanation of last train implies no spade control, but obviously their own poll doesn't override the one performed by the director (who I think did an excellent job and covered all his bases). No adjustment.
Please let me know about any questions or interest or bug reports about GIB.

Why?

My vague guess is N/S want North to be fully informed about the misunderstanding. If West intends 4♦ as last train (denying a spade control), but East understands it as last shortness, then West thinks East showed a 2nd round spade control by bidding 5♣, whereas East denied it, and thinks West showed one by bidding 6♥. I.e., if we know how everyone intended their bids, then we know they are missing a spade control.

Of course, this expectation by N/S has nothing to do with the law.

Anyway, given that North made a truly horrible lead based on the information he got (which should have made a spade lead obvious), he is not entitled to an adjustment based on MI when the correct information would have made the spade lead less obvious.
Did they get their deposit back?

If North had been told that 4♦ was last train, and thus showed no spade control, then 5♣ must show a spade control, yes?

N/S may want to be told what the E/W hands actually are, but that is not the way the Laws work.

Last Train doesn't make much sense in this context. It really should be a diamond control, since 3♠, 4♣ and (maybe) 3N are available as cues.

How does North expect to beat it on a diamond lead?

Maybe West's spades are king-jack and he needs to successfully guess the spades.

It may not make sense to you, but this is how West meant it.

I am not an expert on rulings with screens, but if E/W really play Last Train (which is what the TD suggests since he ruled MI in the first place), why isn't North allowed to have this information?

This is the wrong question to be answered.

There is damage if this north would have led differently given different information (and it mattered). Not what everyone else would do.

It is only relevant if the particular lead chosen was some attempt at a double shot or an egregious error. I don't think leading from a sequence against a slam rather than from an unsupported honour comes into that category.

He is. What he is not permitted is a ruling based on the correct meaning of 4♦ and the information that the other player has got it wrong. Adjustments are based on the presumption that the infraction had not occurred. So the adjustment is as though East had told North that it was 'last train'.

So your guideline is that noth can claim he would have made any lead that would have worked just as long as the lead he actually made is not utterly hopeless? If I were the director, I think a better method of determining what north would have done than believing him would be to poll 7 comparable players and see if any of them would have done the same thing.
Please let me know about any questions or interest or bug reports about GIB.

This player led the ♦K and claims that he would have led a spade with different information.

Comparable players are those that would have led a diamond on the given information.

All the director did is found 7 players that are not comparable with this player as they all would have led a spade on the given information.

You said "It is only relevant if the particular lead chosen was some attempt at a double shot or an egregious error." The director is perfectly within his rights to decide that if 7 out of 7 players of comparable skill level that he polled all led a spade with the same information, that leading a diamond is an egregious error.

Got a law to back that up, or are you just picking using whatever definition of "comparable" suits you the most?

The law requires that the player was damaged if some different people would lead differently then that says nothing about whether this player has been damaged?

This is logic not law.

Ok, I don't think he was wrong. If it just comes down to a matter of opinion I see little more to discuss.

"egregious: Conspicuously bad or offensive."

I don't think you can determine this from a sample of seven.

Perhaps you can if you specifically ask if you think ♦ K is egregious but this is a completely different question than 'what would you lead?'.

Wayne,

why is leading a diamond from a sequence in any way an alternative when you have the explanation: Diamond shortness? There is a zero % chance that you will develop a trick. There is a possibility that possible losers will disappear on clubs, so I guess a spade lead- despite including a little risk- is the normal choice. And there is no way that an information like: 4 ♦ was last train" makes a spade lead better.

Acutally I think a diamond lead is better after the explanation 4 diamond is last train then after the actual given explanation.
Kind Regards

Roland

This depends if there are enough fast tricks. A diamond is safe if declarer has to play on spades (as I mentioned earlier) but not safe if declarer has enough club tricks without playing on spades.

A diamond might also be better whenever partner turns up with the ♦A - not that unlikely (unless I missed something).

I definitely wouldn't be judging that ♦ K was even close to an egregious error.
