In precision with the standard nebulous 1D, what are useful meanings to assign to opener's jump rebid of 2N after responders 1M?

For that matter, does 1D-1N-2N have any meaning?

Thanks

- Solid diamonds
- 6 or 7 diamonds and 3 card support
- mini splinter in higher ranking suit (just thought of that one )
- void splinter (played this for years - never came up)

Whatever you choose is fine.

I don't know what 1D - 1N - 2N is. I've never bothered to give it a meaning.

1♦ - 1M
2NT
Is usually used to show some hands like Phil explained.

1♦ - 1NT
2NT
This one can be used to show both minors, and is rather preemptive. It takes away both 2M bids from opps, who still might want to balance. 5-3 is enough to have a fit...

You can multiplex options, I have always done it this way which is relatively simple and seems to work well.

1♦ 1♥
2♠ = 5-6 max, or mini splinter for hearts. 2NT to find out. Can also include GF splinters (then a direct splinter would show a void).
2NT = 3♦ rebid with 0-2 hearts.
3♦ = 3♦ rebid with 3 hearts.

1♦ 1♠
2NT = 3♦ rebid with 0-2 spades, or mini splinter for spades. 3♣ to find out. Can also include GF splinters (then a direct splinter would show a void).
3♦ = 3♦ rebid with 3 spades.

I would use 1♦ 1NT 2NT (and same if a major is opened) as a rebid of 3 of the suit that is good for notrump.

We play it as max, long suit, singleton (or void) in partner's suit. We haven't discussed it, but we should have 1♦-1M-3♦ as showing tolerence for partner's suit.

The logic is that unless we have a ridiculous number of diamonds, if we have shortness in partner's suit and lack 4 cards in the other major, we must have club tolerence. Therefore, we can't afford to bypass 3♣ with shortness in partner's suit.

Edit: Dammit, jdonn beat me to it.

1♦-1NT-2NT is going to depend too much on the NT range.

We play 10-12 NT

and... 2NT is shows 5-5 or better in the minors (less than opening strength NV)
minimal opener Vul. So those hands would not need to be show here.

You can use 1♦ 1M 2NT to show good 6+ ♦ maximum hand and <3 card M (with 1♦ 1M 3♦ showing good 6+ ♦ maximum hand and 3 card M).

I don't know about 1♦ 1NT 2NT. Maybe strong hand with 6♦ and 4♣.

1♦-P-1NT-P-2NT?

An idea:

1♦-P-1NT-P-?

3♣ = both minors, values
3♦ = preemptive, nautral
2NT = EITHER (1) both minors and preemptive OR (2) diamonds and values, with which you will convert 3♣ to 3♦, or bid again if partner prefers diamonds.

In my system, where 1♦ must be unbalanced:

1♦-1M-2NT is Max unbalanced with 5+♦ and 3 card supports.

1♦-1NT-2NT is Max unbalanced with ♣>♦>=4
