We had the outstanding auction

1♣-1♦
1♥-1♠*
1N-3N
P.

* taken as, and at some point agreed to be, NF

I don't speak Swedish, but are your non-forcing bids normally this strong?

3♣ rather than 3NT might have been my bid.

No, 1♠ was a mistake. (Or maybe our agreement to play it as NF was.)

3nt

[helene_t]

with Shogi I play 1S as a relay. The auction might continue
..... 1S
1n 2S
3c 6c

it's easier with open cards of course.
If you play 1S as natural then probably you play xyz so
....2d
3c 3S
4c 6c

I guess there is no standard application of transfers over 1♣
As I play it on a UK Acol base. East would bid 1N artificial GF:
1♣ 1N
2♣ no other suit
3♣
3♥ 3♠
3N 4♣
4♠ 5♣

Maybe you choose to bid 6 but it is all on the ♥ finesse. The main thing is to avoid 3N

If East chose to bid 1♦, West would not bid 1♥ as that shows exactly 3 card support. So
1♣ 1♦
1N 15 -17 with 2♥ (may have 4♠)
2♦ xyz Art GF
3♣ 4♦ Minorwood
5♣ 2KC + Q♣

Either way East knows West does not have 4♦ so 3N is a bad idea

[fromageGB]

Here's another twalsh auction as I bid it:
1♣ - 2♣ (44xx 11+)
2NT (declining the invitation) - 3♣ (F)
4♣ (can't bid 5♣ because East is unlimited) - 5♣ (not interested in slam opposite expected 12/13)

We use 1♠ as a puppet to 1N

1♣ - 1♦
1♥ - 1♠
1N
-> 2♣ to play 5♣ 4♥
-> 2♦ FG 5♥ 4♠
-> 2♥ to play 5♥ 4♠
-> 2♠ FG 44 MM
-> 2N INV no 5H no 4♠
-> 3♣ 4414
-> 3♦ 4441
-> 3♥ 1444 FG
-> 3♠ 1444 SI

[Kungsgeten]

1♣-1♦;
1♥-2♦ (GF ala XYZ);
3♣-4♦; (opener has 3-2-3-5, responder makes a splinter bid)
4♥-? (cue bid, slam positive)

Not quite sure what responder does then, but my guess is we'll end in 6♣. A good alternative to 4♦ could be to bid 3♠, and now opener will bypass 3NT because of the weak diamond holding.

I can make nothing from the auction given above due to lack of knowledge about the Swedish system.The Standard system which we play the bidding will go
1C-3D ( four card support to two top honours 4414 hand and 15 plus.)
5C-Pass
The hand is not easy for Precision,as 2 opening bids are available namely, 1D and 1NT.Further development, therefore ,will depend upon individual styles and is beyond the scope here.

Common to all versions of Transfer Walsh (or T-Walsh) over a standardish 1♣ opening, including 1♣ as "natural or balanced", is that,

1♦ = 4+ H
1♥ = 4+ S.

Over these transfer responses (1M-1) there are two main variations:

Variation I (which I think of as "Swedish" because it probably originated with Swedish nationals Nilsland-Wirgren):

1♣-[1M-1]; ?:

1M = 3 M or 12-14* bal. w/ 2 M
1N = 18-19 bal., 2-3 M
2N: freed up!

Variation II (which I tbink of as "Dutch" because Dutchman Henk Uijterwaal seems to have invented it)

1♣-[1M-1]; ?:

1M = 3 M
1N = 12-14 bal., 2 M.
2N = 18-19 bal., 2 M

I'm not sure which variation is the most popular worldwide, but my guess is that the Swedish varation is the most popular in the US (at midchart or higher level) and Sweden, at least. (In Norway, noone else seems to play it, but the Dutch variation is extremely popular at higher levels.)

* or 11-13 if you play a 14-16 NT
