I a under the impression that "Strong 10" leads promise the 9 and at least 1 higher honour, but NOT JT9(x)(xx) etc.

i.e. AT9 QT9 KT9x KT9xx and so on

Am I wrong? Do other people have different definitions?

[helene_t]

This is very confusing.

Some say it shows the jack and another honour.

Some say it shows the Jack or the 9, and a higher honour.

[MattieShoe]

Against a suit contract, I'd assume singleton, top of a doubleton, or part of a broken sequence like QT9.

Against NT, possibly part of a broken sequence or top of a 3 card sequence like T98.

But I'm not hip with all the fancy carding rules.

Depends on your lead system.

Some people play coded 10/9 where the lead of the card shows exactly 0/2 higher.

Playing Rusinow, the T would imply the (J)T or Tx.

IMO, the best honour system out there is detailed here (Combine / Sławiński leads):

The way I always understood strong 10 Leads is:

-The 10 is a card in an interior sequence and promises a top honor.
-The J is top of a sequence and denies a top honor.

This means that the lead of the J is from JT(9)xx.
The 10 could be from KT9x, KJTx, QT9x, AT9x, AJTx, AQT9(x).
With QJT(x), they lead the Q.
With T9(8)xx, they lead the 9.

But I may be wrong.

Edited for completeness: Thus, the lead of the 10, promises a top honor and either the 9 or the jack.

The system that was being asked about is "Strong 10s".

[whereagles]

I read about two schemes

1. I believe it's called Vinje - but correct me if I'm wrong. Lead the ten from a broken sequence with 0 or 2 higher cards. Examples:

T97x
T98x
AJTx
KJTx

This scheme also applies the NINE, e.g. lead the 9 from

98x
HT9x (H = A,K,Q)

2. Original Journalist Leads of Jeff Rubens. Lead the T from broken sequence with T9 or JT. Examples:

HJT
HT9

with T9 and no higher honor, the Journalist Lead is the nine.

[gnasher]

I think that there are at least three methods that are sometimes called "strong 10s":
- The 10 promises any interior sequence, ie it includes both KJ10 and K109, but not 109
- The 10 is from 109, AJ10, KJ10 or possibly AQ109, but not H109
- The 10 is from H109, but not 109

Thanks for the link. Looks very interesting and useful. Wish I had a partner to play this with.

When I played strong 10's our agreements were

- 10 shows 2 higher or 1 higher and the 9
- J denies a higher honour
- 9 shows the 10, or is doubleton (or singleton )

A lot of the advantages seemed to spring from the J and 9 leads

I also played this.

I don't get that many advantages, and I hate it when declarer knows what to play from Qxx in dummy upposite Axx

I think some have responded correctly, but it seems muddled.

"Power 10's" is something that I played for a while.

The 10 shows a touching honor (J or 9, 9 being deemed an honor) and is a lead from strength, meaning per force a higher honor (Ace, King, or Queen).

The lead of the J or 9 denies a power holding. So, "Jack denies" is in effect, in a sense, but this is not the normal "Jack denies." It just happens to coincide. 9 is the lead from 109 without any higher honor.

The usual "part two" of power 10 leads is a "Power King" lead, also. The lead of a King is usually a power lead, whereas the lead of a Queen or Ace is less so. Thus, with AKxxx, you would lead the Ace, but with AKJ10, the King. That part looks and acts a lot like "Acxe for Attitude, King for count."

But, this is also different. With KQxxx, you would lead the Queen, as a non-power lead, but with KQJ10x, the King. This lets partner know whether an overtake makes sense. Also, the King is the lead from KQ109, to encourage a dump of the Jack, whereas from KQxxx, the Queen asks., in a sense, for attitude with the Jack.

This creates some ambiguity on a Queen lead, which could be a non-power lead from KQxxx or could be top of sequence from QJ10xx. But, you could, in theory, lead the 10 from QJ10xx as a "power 10" lead. Still, that part gets potentially muddled.
