Quick summary

Don't miss a 3-5 major fit, when responder proposes a major suit.

If not sure partner's 1st suit = 5-card:

assume it was, but give delayed support
partner will go back to the suit if it was a 5-card major

3 responder situations:

5-5, 4-4
5-4
other, e.g. 5-3-3-2,

Case 1 it's usually clear. Responder will bid 5-card suits down the line, and 4-card suits up the line,

Case 2 it's clear sometimes. With 5-4 he bids length first. If the 5-card suit is higher denomination, no problem.. But if the 5-card suit is hearts, and the 4 card is spades, it will sound like a 4-card suit in hearts.

Case 2 it's not clear. Responder is v. unlikely to repeat a 5-card suit, preferring to, e.g. rebid NT, or support one of your suits.

As opener, if 5 might be there, but it's not definite, your responses are these

4-card = immediate support always
3-card = delayed support (5 might be possible)
2-card = double delay (6 might be possible)

Question 1

North is dealer, with a balanced 18-point 6-loser hand and opens 1 Diamond. Partner replies 1 Spade, promising 6 or more HCP. What should North rebid and why ?

Question 1

North is dealer, with a balanced 18-point 6-loser hand and opens 1 Diamond. Partner replies 1 Spade, promising 6 or more HCP. What should North rebid and why ?

Answer

Even though North is balanced, the short club suit has no stoppers. Maybe best to bid a suit? Bid 2-Hearts to promise 16+ and 4-card suit. Only a little lie, and if partner raises in Hearts (promising 4) then you can switch to Spades since he MUST have 5 of them (otherwise he wouldn't have bid Spades first).

Question 2

Have a peep at South's cards. What should he now bid, knowing that the partnership has at least 27HCP ?

Question 2

Have a peep at South's cards. What should he now bid, knowing that the partnership has at least 27HCP ?

Answer

He can't support the Hearts with only 3, and he can't go to NT in case North has nothing in Clubs. But game is on, so he simply asks North to keep describing his hand by using 4th Suit Forcing, which when used at the 3-level is forcing to game.

Question 3

What more information can North give to South ?

Question 3

What more information can North give to South ?

Answer

North now knows that South has a 5-card Spade suit, since the 4th Suit Forcing bid denies having clubs. He can now give delayed support, and raise to game in Spades.

Openers rebid. Unbalanced, Delayed support

3-5? Delay your 3-card support if responder bids

You opened the bidding, and partner changed suit to one of a Major, promising 4+ at the one level. If you have a 3-card suit, should you support it ?

W	N	E	S

1	pass	1	pass
?

If are not sure if partner's 1st suit = 5-card, what should you do ?

assume it was a 5-card suit, but give "delayed support"
after your delayed support, partner will go back to the suit if it was a 5-card major

So, delayed support means respond with something else, and then support it next time.

W	N	E	S

1	pass	1	pass
1NT	pass	2	pass
2/3	pass	/NT

There are three basic responder distributions that give rise to uncertainty:

5-5, 4-4
5-4
other, e.g. 5-3-3-2, or 4-4-3-2

Case 1. It's usually clear, but only after the second bid. Responder will bid 5-card suits down the line, and 4-card suits up the line. But hang on, what if he bids up the line, does that guarantee the first suit is only 4-cards ? No. . ...

Case 2. It's clear sometimes. With 5-4 he bids length first. If the 5-card suit is higher denomination, no problem. But if the 5-card suit is hearts, and the 4-card is spades, it will sound like a "up the line" 4-card suit in hearts and spades. Best to assume that is was 5-4, not 4-4, and give delayed support to the hearts if you have 3.

Case 3. It's also not clear. Responder is very unlikely to repeat a 5-card suit, preferring to rebid NT, or support one of your suits.You won't be able to tell the difference between 5 and 4 in the major. Again, assume 5 with delayed support if you have 3 in your hand.

As opener, if 5 might be there, but it's not definite, your responses are these

4-card = immediate support always
3-card = delayed support (5 might be possible)
2-card = double delay (6 might be possible)
