1d-p-2h(Flannery, 7-9)-all pass[/hv]

 

With s appearing to be in the slot, West is afraid that losers in declarer's hand may disappear given time. Hence the underlead at T1.

 

T1: 4, x, 9, J :)

 

If only that 9 could be swapped for the 8...

What would you lead from 10xxx A9 AQx Jxxx ?

A club obv, I would lead a club from basically anything on this auction. For the 9 to be right you need partner to have the jack rather than the ace AND for the pitch you create for them/trick you give them to matter. That is very specific rather than just playing partner for the CA.

I don't blame E for playing the 9. If pard's holding is JXXX, playing the Q might allow declarer to finesse against the J and play clubs for no losers.

 

Of course, one can argue that if declarer holds AXX of and a stiff , it's obvious to play a towards the K and pitch a loser if the defence takes the A.

 

However, it takes a lot of analysis by E at T1 and IMO, third hand play is much simpler if you can assume that pard will almost never underlead Aces at T1...

Yes, and all hands are easier if you limit what partner can do so that you can restrict the possibilities of what's going on. That doesn't mean you will have better results, partner won't ever be able to underlead an ace when it's right. Surely it is optimal to allow partner to make the right lead and then try to work it out?

Agree -- the underlead of an Ace might indeed be optimal in rare situations (and this hand certainly qualifies, given the scoring method). My aversion is mainly directed towards those who like to habitually underlead Aces on opening leads...

How would anyone who cares to answer rate the lead of the A?

As East, I think the right play depends on knowing partner. There are partners with whom I would play the nine, and those with whom I would play the queen. I underlead aces more than most, and agree with the lead: I would also hope most of my partners would work it out.

I guess problem here is that playing 9 is "automatic play" if only suit existed. I blame 9 as a lazy play which lost now possible trick.

 

I think that rules never to lead from some combinations are very bad even tough it reduces work for partner at trick one. But ace under lead is rarely a good lead.

I still don`t understand the blame for the nine. It catters for Ax, Axx or Axxx.

This is as likely as Jx, Jxx or Jxxx in declarers hand.

So, if your partner leads more often from Jxxx then from Axxx, the 9 is obvious and not lazy at all.

 

And the 9 did not cost a trick yet, just try the underlead again.

You don't always gain a trick by playing the 9 even if partner has the jack. They have a club pitch available on the diamond anyways. It MIGHT gain a trick, but it might not, however it will certainly gain a trick to play the queen when partner has the ace.

He will often need the discard on the diamond for his possible spade loser, and maybe you creat a second discard for a spade if you play your queen now.

Given what's in dummy, it's quite likely that the spade loser will be thrown on Q, either because declarer ruffs them good or because West is squeezed. That's not certain, especially if East remembers to duck when declarer plays a spade to the king, but it's another factor to consider at trick one.

Suck it up and try another small club when in with the diamond Ace. No blame.

When I got in with the A and cashed the A, declarer Janet Jansma turns to me and says, "Good lead. Good idea too that you didn't try it a second time !"

Janet doesn't mean everything she says.
