which card, and why?

[matmat]

You are on defence against 1NT. you play udca, standard honor leads. (not up for debate here, but feel free to mention if you prefer rusinow or whatnot).

 

auction:

P - (P) - 1♣ - (1NT); all pass

 

p puts down the ♥K.

q1. what is your preferred meaning for each card (T,9,2) on this lead (playing udca)?

 

q2. which signal would you give here?

[cherdano]

Q1. Low = I have A or J, High (up to 9) = I don't, T = I have T9.

Q2. ♥T

[Codo]

I like to play K for count A for Attitude, so I give an honest 9 of hearts to show 3.

 

sillyness edited.

 

I play the ten to show T9x.

[Edmunte1]

Q1. Low = I have A or J, High (up to 9) = I don't, T = I have T9.

Q2. ♥T

This is a fine method. You can play the deuce also, partener must have KQJ+ for that lead.

[ArtK78]

Pure attitude situation here unless the lead of the King is conventional (some play it asks for an unblock or count, much like the standard lead of the Ace against NT).

 

Absent any special agreement, I give attitude. But the play of the 10 promises the 9.

 

I play the 10.

[Flame]

Standard K is from KQ10 or KQJ and not asking for unblock.

On K you should play Attitude.

2 = i like the lead.

10 = i don't like the lead and i can afford droping the 10 (usually means i got the 9).

9 = not an option here. (i would play the 9 with 98x to discourage)

 

The question weather i like to encourage the lead isn't simple here.

By encouraging the lead i discourage the "Obvious shift" suit. If you have specific obvious shift rules you know exactly which suit it is, if you dont you have to think and hope partner think on the same waves.

Here the normal rules (from the book by granoveters) says the the ♣ suit is the obvious shift since its a suit Iv bid, this seems illogical seeing the dummy and knowing declarer have a stopper in the suit, yet playing these rules you must follow it.

If you don't have rules, Id could guess ♠ are the obvious shift suit and hope partner guess the same.

Now finally to the card i play. If ♣ is the Obvious shift i would play the 2 to encouraging, if ♠ are the obvious shift id play the 10 to discourage.

I prefer to have the rules even if sometimes they aren't perfect.

I think the 10 is right and the 9 is simply wrong. The problem is the 9 leaves open the possibility you have J9 doubleton but the T rules out JT doubleton, so why not give the most clear signal possible?

[kgr]

I expect partner to have ♥KQJx.

I don't see a reason why he should lead ♥K with less, eg ♥KQxx or ♥KQxxx.

Probably he also does not have anything outside ♥ and it is best that ♥'s are continued. I encourage with ♥2.

UDCA any card except the 9 is fine because partner has KQJ for the lead so if he continues small, it would be just fine. If I am playing with an unknown, I'll go for the clear 10. The nine accomplishes nothing and as a signal it is vague, even misleading when it denies 109x.
