Opener's Rebids
If you open the bidding and I change suit, then you MUST bid again. That is because my points are unlimited so we might have game.

Support partner's suit
If you have a fit for partner's suit then you should tell partner the good news immediately. You promise 4 trumps when you raise partner's suit.

Opener raises partner's suit
♥12-15 raise one level
♥16-18 jump raise
♥19 bid game

	♠ A2
	♥ KJT2
	♦ KJ
	♣ Q7642

South	West	North	East
1♣	P	1♥	P
2♥

On this hand you can raise to 2♥. Partner has four hearts and 6+ HCP. A raise to 2♥ by the opener shows 4-card support and 12-15 HCP.

	♠ A2
	♥ KJT2
	♦ KJ3
	♣ A764

South	West	North	East
1♣	P	1♥	P
3♥

A raise to 3♥ by the opener shows 4-card support and 16-18 HCP.

	♠ A2
	♥ KJT2
	♦ AK3
	♣ A764

South	West	North	East
1♣	P	1♥	P
4♥

With 19, you're strong enough to go to game. Partner has shown at least 6 HCP, you have 19, so that's 25 in total.

Bid a new suit
If you can't support partner, bid a new suit if possible. Remember that you should describe your hand as accurately as you can. It's better to bid a new suit rather than rebidding your first suit.

	♠ 2
	♥ KJ3
	♦ KQJ54
	♣ QJ64

South	West	North	East
1♦	P	1♠	P
2♣

Bidding a new suit gives partner more information than rebidding a suit, so so it's better to bid 2♣ on this hand rather than 2♦. This is NOT a limit bid, and you could have up to 18 HCP.

Why can't you be more specific and limit the strength of your hand by bidding 3♣? The reason is that a jump in a new suit at the 3-level is forcing to game.

Bidding a new suit at the 2-level also implies that your first suit was 5 cards long.

	♠ 2
	♥ AK3
	♦ AQJ54
	♣ AJ64

South	West	North	East
1♦	P	1♠	P
3♣

This time you can jump, as you are strong enough to force me to game, even if I have only 6 HCP. A jump in a new suit shows 19.

Rebid Notrumps
If you can't support partner or bid a new suit, you can bid notrumps. This tells partner that you are too strong to open 1NT. It also tells partner that you have a balanced hand.

12-14 - Open 1NT
15-19 - Open 1♠, ♥, ♦, ♣ and rebid notrumps.

	♠ AJ7
	♥ A732
	♦ A754
	♣ K3

South	West	North	East
1♦	P	1♠	P
1NT

You have 16 hcp, which is too strong to open 1NT. Open your lower 4-card suit as usual and then bid notrumps at the minimum level. This promises 15-17 hcp.

South	West	North	East
1♦	P	2♣	P
2NT

If partner responds at the 2-level, your minimum rebid is 2NT.

	♠ AJ7
	♥ AQ76
	♦ A876
	♣ K3

South	West	North	East
1♦	P	2♣	P
3NT

With more than 17 hcp, you must jump the bidding one level.

Principle
Show your balanced hand with your 1st or 2nd bid

Opener's Notrump Rebids
12-14 - Open 1NT
15-17 - Rebid NT at a minimum level
18-19 - Jump rebid in NT

Rebid the first suit

You can't support partner, nor bid a second suit, nor bid notrumps this time. You only have one choice which is to rebid your own suit.

Opener rebids first suit
• minimum rebid = 12-15
• jump rebid = 16-18

	♠ 92
	♥ AK
	♦ KQJ543
	♣ 532

South	West	North	East
1♦	P	1♠	P
2♦

You'll have to rebid your diamonds, to show one long suit and nothing else. Rebidding your own suit at a minimum level , promises 12-15 HCP and usually shows a 6-card suit.

	♠ A2
	♥ AK
	♦ KQJ543
	♣ 532

South	West	North	East
1♦	P	1♠	P
3♦

You still have only one suit to rebid here, but your hand is stronger. Jump to 3♦ to show a 6-card suit and 16-18 HCP.

With a very strong hand and only one suit which you want to be trumps, you can jump to game. This shows 19-21 HCP and a long solid suit.

	♠ A3
	♥ AKQJ543
	♦ KJT
	♣ 9

South	West	North	East
1♥	P	1♠	P
4♥

You are not interested in anything but hearts, so tell partner the news that you have a great suit and a strong hand.

• Support partner's suit
