Grounds for divorce?

[nige1]

I watched Frances and Jeffrey star in this deal, from the EBU Premier League, on viewgraph, so I know the winning action.

You must have been distracted while you were watching, because they did not star in this deal. I looked it up a few minutes ago.

Maybe not :)

Star - act in leading role

I hope the real ploy was to get Jeffrey to start contributing to these threads regularly. That would be worth something.

The opening leader's partner has written a hand simulation program.  The program was run assuming partner to have a 1♠ opener and declarer to have 7 clubs to the AK and a spade stop.

 

The results were as follows:

 

Spade works 15 times

Heart works 26 times

Low diamond works 20 times

Ace of diamonds works 23 times

Club works 14 times.

 

[in fact those cases include 11 where any lead works and a further 12 where no lead works.  There are 13 cases where a heart lead works and a spade doesn't, but only 2 where the converse is true.]

 

So if your spouse's simulation program demonstrates that your opening lead was correct in theory, then that is certainly not grounds for divorce!

The problem with this analysis is that it probably does not include those cases where the A♦ followed by any switch still beats the contract (maybe it does, I don't know).

 

If it does not include these cases, then the A♦ lead (winning whenever diamonds were right), or the A♦ followed by any switch that still beats the contract, will make the A♦ the superior lead, imo.

Yep, certainly a very good start of his very first post. Keep it up.

No, he has withdrawn after they gave him 6543 543 543 543. Not fair towards a newbie!

The opening leader's spouse's partner says that he included ace-of-diamonds-and-switch in these i.e. there are 20 hands where leading any diamond is right, and another three where the ace in particular gains either because you can switch or because it drops the singleton king.
