One of Major Opening Bid
- I open 1NT with balanced 14-16 hand even with a five card major
- Acol two bids in major are opened 2♣ so the quality of the strong one suited hands is limited
- Very strong two suiters are opened with MisIry Transfer preempts, so jump shifts after opening a major is limited by the in ability to open with the MisIry bid.
- I will open 1C with 5-5 in the black suits when strong, when 5-5 in the black suits and very weak (for opener), I will open 2S (see chapter on 2M opening bid). And when intermediate, I will open 1S.
- With 5-5 in hearts and a minor, I open 1H (or 2H if clubs and weak)
The responses to 1M are based upon show support with support, and several ways to "unload" traditional forcing 1NT. Also, remember that over 1H, we play modified Kaplan Inversion, so be sure to read the chapter on that to see the exceptions to the auctions given below.
Reponses to 1 MAJOR
- 1NT = semi-forcing (See also Kaplan inversion)
- 2C (after 1st/2nd seat opening bid), three way,
---------> 5+ Clubs, GF values
---------> (10)11+ balanced hand
---------> 7-9 hcp 4 card support or 8-12 with 3 card M support - 2C after 3rd/4th hand opening, 3 card Reverse Drury
- 2D after 1st/2nd seat opening, GF, 5+ diamonds
- 2D after 3rd/4th seat opening, 4 card drury
- Raise to 2M weak raise, 3 cards, up to bad 8 hcp
- 2H (over 1S), GF, 5+ hearts
- 2S (over 1H), weak, six card plus suit
- 2NT - Jacoby 2NT Plus (limit raise or better, 4 card support)
- 3C/3D = invite, six card suit, fair values (think 9 to 12)
- 3H (over 1S) = invite, six card suit, fair values (think 9 to 12)
- Double jump shift = splinter (limited values)
- 3NT = three card support, 13-15 (without bid 2C first, with more bid 2NT).
- 3M = preemptive 4 card support, generally 7 hcp or less
- 4M = to play, generally five card support
- 4NT = Natural 18-19 hcp, balanced, to use RKC, start with 2NT then bid 4NT
In choosing to opening, I apply ZAR points. With 25 ZAR points and four or more spades I tend to open, with 26 ZAR points and 4+ spades, I do open. With 26 ZAR points and five hearts, I tend to open, with 27 ZAR points and five hearts, I do open.
Three suiters with a five card major. We open 2C with three suiters and five or less losers with five or more controls. An exception is with weaker versions of 5440 hands where you have five losers, or four losers and weaker hcp totals.

Open 1S, planning on 2C over 1NT, 2D over 2C, 2H over 2D
Notice the 2C rebid, over 1NT is Riton 2♣ showing better than mininum. Given chance, you will rebid 2♥ showing 5-4 and good 15+. Over 2♣ by partner, you are too good to respond 2♥, so you bid 2♦ showing better than minimum, planning on bidding hearts next.

♣ 9
Open 1S, rebid 2D over 2C or 1NT (different meaning). Over 2C, 2D shows better than minimum, while over 1NT, 2D shows minimum with diamonds. How can it be better than minimum over 2C and minimum over 1NT. The answer is simple. Over 1NT, your parnter may be long in clubs and weak. Over 2C, if he is long in clubs, he is strong. If over 2C, parnter might have a spade fit, over 1NT he DOES NOT HAVE A SPADE fit. With possible diamond or spade fit, this hand is a ZAR monster. 14 distributional, 12 hcp, and 5 controls for 31 ZAR points before fit is found. 30 or more Zar's virtually always requires 2D response to 2C.

Open 1S, no need to preempt 3H (trasfer) with opening hand. Note Zar would open this with a 3 level preempt. So if you feel that 3 hearts (transfer to 3S preempt) is right, go for it.

Open 1S, rebid 2D over 2C or 1NT (different meaning). Over 2C, the 32 ZAR points is too much for a 2S rebid. Over 1NT, the weakness of diamonds and the likelyhood partner is long in clubs and weak make anything but 2D ill advised.

This time you respond with a weak hand
because if parnter has good hand and hearts
you can easily have game. Even good hand
with spades your two kings and spade jack
might be more than enough for game.
2C is riton 2C, showing good hand, and 2D
is waiting for open to define his hand.
When parnter bids 2H (at least 15 hcp, four
hearts, ZAR points kick in. South has 23 fit
Zar points more than enough to bid game.
