I always want GIB to declare my hands. He plays better ; )

I'm sorry to hear that.

Yes..might be time to study declarer play a wee bit. (Or lots more..like 30 minutes almost every day)

Barry Crane's Rule is that the Queen is over the Jack in a minor, under the Jack in a major.

Declarer holding QJ of trumps is more likely to play the queen first, so if the cards get shuffled badly, the queen will often be over the Jack on the next board.

 

I would be surprised if this has ever been statistically validated. There is 1/4 chance the QJ are in the same hand, maybe some 1/3 chance that they will be played in subsequent tricks, then maybe the chance that the queen is played before the jack exceeds the opposite order by 1/4, then maybe a chance of 1/4 that the cards are shuffled sufficiently badly, then maybe a chance of 4/5 that the deck was dealt clockwise. This gives a probability of something like 50.5% that the queen is over the jack, so we would need appr. 20000 deals in order to discover the trend with anything near statistical confidence.

 

OK, this is just some made up figures, and I suppose the true probability might be as much as 53%, or it might be less than 50%. Anyway, in practice you will have plenty of more helpful pieces of information (auction, play, opps tanking or smiling).

 

I wouldn't call it "superstition" as it is based on reasoning. It just happens to be nonsense IMHO.

That still doesn't answer my question: why the difference between major and minor? That's what Barry Crane's superstition is about. Is it because it's more likely that a major suit will be trumps than a minor suit?

Maybe that majors are more likely to be trumps. Or is that the reverse of his suggestion?
