Are there standard meanings for these jumps to game? eg in terms of length, overall strength, strength in the suit, strength outside, fit for partner etc. what are the differences between them?

1. 1♦ 4♠

2. 1♦ 1♠ 1NT 4♠

3. 1♦ 1♠ 2♣ 4♠

4. 1♦ 1♠ 2♦ 4♠

5. 1♦ 1♠ 2♥ 4♠

6. other similar sequences I may have omitted

Also, are there any difference if the opener's first suit was ♥?

1♦-4♠

Something close to a 3♠ opening, not exactly that.


1♦-1♠-1NT-4♠

about 11-14 with 6♠ (maybe weaker with 7)


1♦-1♠-2♣-4♠

I make game with 2.5 - 3 cover cards and singleton spade.

1♦-1♠-2♦-4♠

Same as above, but having soem lengt in diamond would require less honnor strenght.


1♦-1♠-2♥-4♠


This depends on our agreements regarding weak jump shifts (2 and 3♠), I find it hard to get a hand for it with my agreements, a missfitting 6-4 with a good suit comes to mind.

And I don't think ♥s make any significant difference.

1: 1D 4S = Very long, very weak hand/spade suit. Opener with bal 18-19 is expected to pass. Something like: 8 spades to the jack and out. Anything stronger is a 1S response.

2: Sign-off with 6[+]sp and no slam interest

3/5: Self suffient spade suit and out. 4 of top 5 spades with 6-card suit or 3 of top 5 with 7-card suit. Opener may bid on with extra values

4: Same hand as 3/5, but since opener limited hand with 2D, opener is expected to pass.

4S directly basically shows KQJxxxx and out.

The second auction is different from the others: the 1NT bidder has describerd his hand and will never take another call. The 4S bidder can have 6 bad spades or 7 good ones, 11 HCP or a poor 16. Just any hand where he thinks 4S is the right spot.

Auctions 3 and 4 are very similar, in either case responder is likely to have 7 spades or 6 very good ones, and at least a shot at game. Certainly a better hand than a direct 4S bid.

Auction 5 is quite unusual, here opener has shown a very good hand with two other suits. 2S would be forcing for most (at least in the US), so 4S should only be bid with those hands where you are really quite sure that 4S is the right spot. I'd say a minimal response, 7 spades with good fillers but not as good a suit as in the first auction.

1. I don't know, not sure I have ever bid this, but I would expect a very weak hand with 8 spades.
2./4.: Really there is no agreement necessary, responder is just placing the contract, he could have many very different hand types.
3.: Not as wide-ranging as 2/4, good suit, nothing much else.
5. Very weak and long spades

I agree with all of this and suggest that auctions like auction 5:
1m-1M;reverse-4M
should show a very specific "picture jump" kind of hand.

I guess you don't rebid 1N with a stiff

Stiff K, maybe. Some of us don't promise 6 cards in the minor when we rebid 2m.

It's interesting to try to come up with a "picture" for 1♦-1♠-2♥-4♠. My vote would be for a two-loser, 7-card suit with a side high card, something like QJ109xxx Kx xx xx.

You know very well that I do .

Still, with J109xxx x Ax AQJx I would rebid 4S over 1D-1S-1NT, I think.
