if hearts agreed,
4
if spades agreed) is LTTC.We play some sort of Roman Keycard Blackwood. This means that the King of the agreed trump suit counts as a fifth Ace and it is possible to find out about the trump Queen. By bidding Blackwood, you commit the hand to the six level if only one of these cards is missing. You cannot use Blackwood and sign off when you discover that only one of these six cards is missing. Since people seem to do this all of the time against me, perhaps it is an acceptable practice in some schools of bidding theory. It is not an acceptable practice in the methods I am discussing. Hopefully, you will gain some insight into why this is so as you read my examples.
I will also refer to a convention called Lackwood. As you will see, when you play LTTC, you can no longer cue-bid in the LTTC suit (Diamonds if Hearts is agreed, Hearts if Spades is agreed). Lackwood can be used to resolve any problems of missing controls in the LTTC suit while retaining the possibility of bidding grand slams.
Lackwood is always a bid of 5 of the agreed major. It is either a bid immediately after LTTC or as a direct raise of 4 of the agreed major. Bidding Lackwood always denies control of the LTTC suit. Lackwood is a last resort. It is a convention you should go out of your way not to use. Most of the time you can infer the presence or absence of a control in the LTTC suit and simply bid Blackwood. Here are the responses to Lackwood:
| PASS | - I have no control in the LTTC suit |
| 1st step | - First round control of LTTC suit & 0 or 3 Keycards |
| 2nd step | - First round control of LTTC suit & 1 or 4 Keycards |
| 3rd step | - First round control of LTTC suit & 2 Keycards no Queen |
| 4th step | - First round control of LTTC suit & 2 Keycards & Queen |
| 6 of our major | - Second round control of LTTC suit |
There is no simple rule for what it means to bid LTTC since it doesn't always mean the same thing. Assuming that we have agreed a major suit at the 3-level, there are 16 possible LTTC sequences. In 4 of these sequences, it is necessary to play that LTTC has a very specific meaning. The first couple of rounds of the following auctions have been omitted. The first bid in each auction sets the trump suit.
AUCTION 1:
3![]() |
3NT | |
|---|---|---|
4![]() |
4![]() |
(LTTC) |
shows a control in Diamonds and denies a control in Clubs (see last article).
4
is LTTC. In this example
LTTC means:
"Partner, I have forced you to cue-bid and I do not know how good your
hand is. If I was to bid 4
it would be an absolute signoff, a statement that we have at least 2 Club
losers. I have the Club control that you are lacking, but my hand is flawed
in some way so that I cannot bid Blackwood. Perhaps you have sufficient
strength to move towards slam (by bidding Blackwood or Lackwood depending
on the Heart situation).
AUCTION 2:
3![]() |
3NT |
|---|---|
4![]() |
(LTTC) |
).
4
is LTTC (denying a Club
control). In this example LTTC means:
"Partner, you have shown a strong hand with no control in Spades. If
I also had no Spade control, I would bid 4
as an absolute signoff. I cannot bid 4
(showing both Spades and Clubs controlled) or bid above 4
because I do not have a Club control. Therefore, I am bidding LTTC. Since
my hand is still unlimited, you are expected to continue (Blackwood or
Lackwood depending on the Diamond situation) any time you have a Club control."
AUCTION 3:
3![]() |
3NT | |
|---|---|---|
4![]() |
4![]() |
(LTTC) |
is a cue-bid. 4
is LTTC, denying
a Diamond control. In this example, LTTC means:
"Partner, I have taken control of the auction, but I am lacking a Diamond control. If you do not have a Diamond control either, please signoff. Otherwise, please bid Blackwood or Lackwood depending on the Heart situation."
By bidding 4
instead of
4
(LTTC) the message would
be:
"Partner, I have shown extra values, but I am lacking a Diamond control. If you have a Diamond control please use your judgement as to whether you should bid PASS or bid Blackwood or Lackwood depending on the Heart situation."
AUCTION 4:
3![]() |
4 |
|---|---|
4![]() |
(LTTC) |
is a cue-bid
denying serious slam interest (else 3NT). 4
is LTTC. In this example LTTC means:
"Partner, you have told me that you have a minimum hand, but I am still interested in slam. However, I am lacking a Diamond control. If you also have no control of Diamonds, please signoff. Otherwise, please bid Blackwood or Lackwood depending on the Heart situation."
In the first two auctions, LTTC is a statement that a control exists in a particular suit. In the last two auctions, LTTC is a question that asks for a control in a particular suit. In all of these auctions, LTTC is completely artificial, saying nothing about the suit mentioned.
There are 12 more possible LTTC auctions where the meaning of LTTC is not clear. Here are some examples:
AUCTION 5:
3![]() |
4 |
|
|---|---|---|
4![]() |
? |
is a cue-bid denying serious
slam interest and denying a club control. What does 4
mean? It must show extra values and a club control. Without either of these,
you would signoff in 4
. There
are 3 possible further interpretations (of which only one can be used):
otherwise.
bidder is still interested
in slam, but needs help somewhere. Their partner can choose to bid Blackwood
with a Heart control or Lackwood without one.3![]() |
4 ? |
|---|
clearly denies spade and
club controls as well as serious slam interest. This time there are only
2 possible interpretations (of which only one can be used):
instead would deny a Diamond control.
with a really bad hand and a Diamond control. With a really good hand with
controls in Spades and Clubs, the 3
bidder can still choose to bid either Blackwood or Lackwood (depending
on the Diamond situation).Bidding LTTC means that you are still interested in slam, but do not have sufficient values or controls to bid Blackwood. You would like to involve your partner's judgement.
If your hand is suitable for Blackwood, but you lack a control in the LTTC suit, bid LTTC, not Lackwood. Hopefully, partner will take over and bid Blackwood. If partner signs off you can still judge to use Lackwood if you want.
Bidding 4 of the agreed major instead of LTTC is an absolute signoff when:
When an 8+ card major suit fit is agreed at the three level and the bidding is forced to game (as in 2/1 auctions):
for Hearts, 4
for Spades) is
Last Train to Clarksville. Bidding LTTC versus bidding 4 of our major can
carry different messages. LTTC means either:
is a "transfer to Blackwood". This is an especially useful bid if you want
to bid RKCB but fear a response of 5
(2 with the Queen) will get you too high. Having your partner bid Blackwood
will solve the problem. You should also bid 4
instead of 4NT if your own RKCB response would be 5
and you lack the trump Queen (you can figure out why).If you and your partner feel that you thoroughly understand this article and my last one, you are probably ready to try these methods. I suggest that you practice bidding with computer generated hands (I sell them) before you actually try playing the structure I have described.
The rules are not clear in this area, but I think it is best not to alert serious 3NT, LTTC, or your cue-bids. Instead inform the opponents as to what your auction meant before the opening lead is made.
