I could lead a high spades to show ace and a low to show the A/K. So for me the question is between showing the Q or a trump promo. Partner K look like hes asking for the Q rather than count in this spot (how are we going to defeat this if opener got a singleton club ?) so I give attitude for the Q. High= dont count on me for the Q.

If west had the 9 2 is a very interesting contract to play/defend.

South should pass, north X and I convert with south hand and lead trumps. Possible that west raise to 3

Showing your long suit is very useful for the defence, twice today I lead doubleton only to hit opener AKJxx, AQTxx. It didnt matter since they made 5 instead of 4 but it cost 2 tricks

1NT-2H-2S-3NT-4S
1NT-2D-2H-3NT-4H

If opener show their 5 card suit and we still lead its going to be a singleton 100% of the times.

Your missing the point, if you simply bid 4 you might miss a good slam when responder was maximum but not quite good enough for a quant, if you cuebid you leak information on hands where responder is far from slam. So 4 is a no cost way to possibly find slam without giving information that could be useful for the defence.

I agree that 4m/4 shouldnt be a cue, but bidding 4C to show a good 4 raise (say nothing about ) can lead to good slam, responder can easily have 15pts bal 5332 not good enough for a quant 4Nt.

Even a hand like

98xxx
AT
KQJ
KQJ

will often lead to hopeless 6Nt if you bid 4Nt quant. Assuimg 15-17 range where many 17 count with 5 card suit are too good for 1Nt

Is it a preference or its just because a poor man freebid is still a freebid ?

Side question do you think OP auction is significantly different than

(1H)–X—(P)—1S
(3C)–3

For a 1Nt opening It look clear to me that the odds that a descriptive 4m help the defense put you down is higher than the odds that a descriptive 4m (natural good suit) pay off dividend by reaching a plus score (make 6 or avoiding a bad 6) that couldnt be reached with a omnibus 4, but I agree that both are quite low. For a 2Nt opening its less clear since slam is more likely.

“But in the partnerships where we do not play that, I think having 3C as natural and forcing is far too valuable to waste on using it as showing an invitational hand.”

after 1NT-2C-2M-?? we play

3C= artificial, fit in opener major (inv or slammish)
3D= 5D+4OM (OM =other major)
3H= 5+4OM low short (43)15/(42)16
3S= 5+4OM high short (41)35/(41)26
4Y= rest are void splinters (with sing splinter we bid 3 first)

This method is worth a bunch of easy imps.

If 4 is a cuebid and doesnt promise extras than it should ask for a control. It also mean that 4S should deny a control and force south to keep bidding with the control (today is your lucky day and we can assume you cannot have a slmmaish hand with no ctrl in the round suit). Otherwise you risk going at the 5 level with a control missing and not enough values so its a fail on both count.

That why in situation where your able to show control in 2 side suit showing control in the 3rd suit is more important that general value (you can reach 5 level with not enough values for 6 but you have ctrl everywhere) but when you cannot be sure to have controls in the 3 side suit the bid need to be last train.

4 followed by 4 is weaker than 4 followed by 4 wether 4 is last train or a cue.

South bidding 4 make no sense. North made 2 slam try and south got

a 5th trumps & a doubleton (he could be 4333)
5 in controls (average for 14-16 is closer to 4)
15 in a 14-16 range.

South is clearly above average so he cannot signoff.

North hand however isnt forced to bid 4, his hand is probably only worth one slam try.I think that even if north bid 4 instead of 4 south should still keep bidding.

Perfect hand to make a responsive double instead of 2S. So that way when i bid later my partner know that I have a 5/6m on the side.

Passing 3 is lol.

The notion that 3D could be/should be/is forcing is based on the asumption that 2 show constructive values. In my partnership it doesnt show a lot so 3 isnt forcing. Wiuth some old school player I know that their 2S show some stuff so for them 3D would be forcing.

Playing with an last minute partner I would stick to the agreement I use with all my last minute partner “in doubt dont make a bid that could appear NF with a GF hand”.

After 4 its impossible for south to stop at the 4 level. Its 14-16 1Nt.

So south job is to show that he doesnt have a club control.

4C-4D
4H-5D
??

5 = im also missing control
5 = Ive got the ctrl but maybe I already overbid.

That is usually how we play our symm relay,

2S= low short
2NT=5422
3C=5413
3D=5512
3H=6412
etc

2S-2NT-?? (low short, ask)
5431
5521
6421

but here hands with 4M & a fit are too likely so we need more space (note that we play splinters =void)

Usually when the control situation is unclear (no way to know if you have a control or not) LT is better.

1S—4D (splinter)

or

1H–4C

I think most would treat 4M-1 as last train rather than control unless their splinter show a very narrow range.

However if the bidding goes

3S–4D (3S agreeing fit, 4D NON-serious)
??

everytime you minimum or dont have a control you need to bid 4S to play

if your missing the control you need to bid 4H.

however at tables where they play 3nt non-s it will go

3S-3NT (3S agreeing fit, 3Nt NON-serious)
4C-4D (both showing controls)
4H-?? H control not enough value to ask for keycard (LAST TRAIN)

so they are able to show control everywhere and still ask for last train.

Yes its another small reason why 3Nt non-serious is slightly better. When the person who bid 4D deny a control but show serious interest its unlikely that he missing controls in both and .

3NT–4D (3NT is non-ser, 4D show a serious interest and deny ctrl)
??
or

4D–?? where 4D is serious.


4H = control (ask for a ctrl)
4S = no control
4NT+ = both

note that if you have the K and the K and you know that partner doesnt have a control you can bid 4H and partner will only go on with a control, you will not bypass 4S when you are missing the and ace. So its more precise to say 4H ask for a ctrl rather than deny a ctrl.

Very few players have a good understanding of last train IMO. Last train ask for extras not for a control, sometimes it doesnt promise a control and sometimes it does

There is 3 main cases assume is trump and assume north is the one bidding 4D.

4-4-?? (both showing controls)
4= H control not enough value to ask for keycard (LAST TRAIN)
4= no H control may have extras, if north got a control he cannot pass
4NT+= control and enough to ask for keycard.

This is the way that work best with 3nt non-serious, north cannot pass 4S with a control but you will never reach 5 level with 2 quick loser.
——————-
4D-4H-?? (where 4D show a control and deny a control, so 4H promise a control but deny a control, (NOT LAST TRAIN)

north is again force to bypass 4 if hes got a control
—————-
4D-?? (4D is a splinter or show a control but we dont know about the control)

4H= LAST TRAIN, may or may not have a or control is asking for extras
4S= weaker hadn say nothing about control.

So last train is only “on” when the person bidding 4D may have a control.

The 4–4–4 sequence is the only case where last train is on and promise a control.
