5.1. Principles:
Weak/PRE vs. strong openings, opening/AVG vs. weak.
Pass vs. strong/F1 bids contains the strong hands.

Why not natural responses?
->Because searching of major fit is primary goal and low level xfers allow to check it and still stop at 2 of major.

Rebids general

2007-04-23T13:22:00.002+03:00

3. Rebids:

GF, 5+-4+ in majors(major opening) to 1NT response;
Extra distribution (5+ unbid minor or 6+suit to rebid), RF, not GF, if last Pd bid was negative (like accepting xfer at 2 level) with paradox continuations.
3C:
GF, deny 5-5, 6+ or FIT, if last Pd bid doesnt show minor;
GF, FIT, if last Pd bid show minor;

Discussion:
Why so many cheap bids for majors?
-> With majors respoder is under pressure of possibility of major game with few points. Cheap major bids allow to check this possibility without overbidding. Of course you need to pay the cost, using unsuitable high bids for minors, but such problematic hands are rare enough.

2.4. 1H/S - ?:
1S: 2+Re, 4+S
1NT: 2Re-3LRe, NF, can have FIT
2C: 2+Re, 5+unbid major

game-raise: 1-2Re, 4+FIT, PRE
4NT: RKCB
5C/5D/5H(1S)/5S(1H): 4+FIT, Void in bid suit, ERKCB

Discussion:
-> Why not mini-SPL's or fit-showing jump shifts?
So as not to give info to the OPP, before it is certain we need it ourselves! Pd can still continue with a GTRY, but can also pass or bid game, giving less information to OPP's.

2.5. 1NT(2Op)- ?:
2C: 1+Re, Stayman, guarantee 4 major

Discussion:
Why 4 cards major xfers?
-> They give you possibility to use them instead of 2C Stayman, when you afraid of lead directing double to it. They also allow NF rebids of Stayman at 3 level of minor.

6C/D/H/S: 1-3Re, 8+, PRE
6NT: 1-3Re, 6+-6+, PRE, normally C-D
Discussion:
Why 2C Mexican?
-> It is dangerous zone of HCP BAL for overbid/ubderbid. In competition can't be shown normal way.
Why xfer PRE, combined with strong 2 suiters?
-> Xfer preemts rightside the contract. Strong 2 suiters are dangerous for overbid in high competitive auctions and very hard to manage after strong artifical opening.
Why 2D include any GF?
-> Because it comes too rare and is not much better, if you open it with 1 way strong opening at 2 level...

Zones of strength

2007-04-23T13:17:00.000+03:00

1.4. Zones of HCP:
Note: Bottom value of zone are good HCP, while top value of zone are bad HCP.
Note: Expecting losers are for UNBAL(5-4 or 6).
Note: Very UNBAL hands (5+-5+, 6+-4 or 7+) with honors in long suits can be count as next zones of HCP if all other requirements are satisfied.
Note: Zone determination modificators: L - lower part of zome; U - upper part of zone. + zone and above; - from - to zone;
Ex: 2URe = 7-8 HCP; 2LOp=14-15 HCP.

1.4.1. Zones of Re:
1Re: 0-5HCP, 10-9L, 0-1KC; Op, Ov, Re: Pass or PRE; Negative after forcing bids.
2Re: 5-8HCP, 9-8L, 0-1KC; Op: Pass or PRE; Ov: Pass, PRE or 1 level overcall with 5+4+(1) or 6+; Re: 1/1 or PRE.
3Re: 8-11HCP, 8-7L, 0-1KC; Op: Pass or PRE; Ov: Pass, PRE or 1 level overcall with 5+4+(1) or 6+; Re: 1/1 or PRE.
1.4.2. Zones of Op:

Slam conventions

2007-04-23T13:15:00.000+03:00

1.2. Slam conventions:
BW = Roman Blackwood (not Keycard). Ask for Aces.
A jump to 4NT is BW, if no FIT or new information about length in suits.
Step-responses: 0/3 A, 1/4 A, 2 A no K, 2 A + 1 K...
The next ask is the cheapest suit, for K.
Step-responses: 0 K, 1K...
The next ask is again the cheapest suit, for Q.
Step-responses: 0 Q, 1Q...
Sign offs: any non-cheap suit, or 5NT and above.
Note: After a NAT 3NT, 4NT is quantitative.
EBW = Exclusionary Roman Blackwood. Asks for A's outside the jump suit.
A double-jump is EBW, if 4NT would be BW.
Answer as to BW, but don't count the A in the jump suit.
Sign offs: a non-cheap suit or 5NT and above.
RKCB = Roman Key Card Blackwood. Asks for KC.
Note: If a FIT in 2 suits, then 6 KC's: 4A + kings of both suits.
A jump to 4N is RKCB, after a FIT or new information about length in suits.
Answers by steps: 0/3 A, 1/4 A, 2/5 A no Q trump, 2 A + Q
Next ask is the cheapest suit, for the Q of trumps, if unknown.
Answers by steps: no trump Q, yes trump Q
Note: If a FIT in 2 suits, then the major trump Q is resolved first.
Next ask is the cheapest suit, for side K's, with all other bids asking for Q or DOUB in the bid suit.
Answer: 6 of trumps no, other bids yes.
Sign offs: Any bid of the trump suit.
ERKCB = Exclusionary Roman Key Card Blackwood. Asks for KC outside the jump suit.
Answers as to RKCB, but don't count the A in the jump suit.
Sign offs: as RKCB.
CUE = Cue bids. Shows any control after a FIT - A, K, Sing or Void.
Use a CUE after NAT bids to show control in the side suit.
Principles before KC limitation:
-Skipping a suit denies control in it.
-Continuing to CUE after a skipped suit shows a control in it.
-Continuing to CUE doesn’t guarantee a MAX.
-Bidding 4 in a FIT with no skipped controls shows a MIN.
-a CUE in a previously skipped suit show a Q or DOUB.
-Jumping to 5NT shows a Void in a side suit, even # KC's.
-Jump in a suit shows a Void in the side suit, odd # KC's.
KC limitation (parity of # of KC's held by one player, aka TURBO):
-cheapest bid: 4NT (without a jump), bid in shown SING/VOID or 4 in GF fitted minor is a CUE showing an even # of KC's; Next such bid show Q trump.
-Skipping this 4NT CUE, bid in shown SING/VOID or 4 in GF fitted minor shows an odd # of KC's.
Note: After a FIT at the 5 level use 5NT just like 4NT.
-Continuing to CUE after KC limitation below the 5-level of trumps shows enough KC for slam, but missing the Q trump or equivalent, or is a CUE for grand slam. With the Q of trump Pd continues to CUE for a possible grand slam.
-Continuing to CUE after KC limitation above the 5-level of trumps shows enough KC for grand slam and the Q of trump or equivalent.
Note: If CUE after KC limitation below 5 in FIT isn't available, then 5NT cue show enough KC for slam, but missing Q trump or equivalent.
Sign offs: Any bid in trumps = missing a control in a skipped suit or not enough KC or Q trump (after 4N).
SPL = Splinter. Limited slam try with a FIT, shortness in jump suit.
Use a SPL if nothing wasted in the short suit makes slam possible.
Splinters are: a jump in a side suit after a fit, OR a double jump in an unbid suit without having previously raised, setting trumps in the process.
Principles: same as with CUEs.
Sign offs: Any bid in trumps.
Note: Any unusual jump in a usual NAT bid is also a SPL.
1.3. Slam conventions after opponent intervention:
Note: After intervention of 4NT or higher: pass - even KC/A; DBL - odd KC/A
1.3.1. Over cue bids:
1.3.1.1. DBL:
returning to trumps: no control in opponent's suit.
Pass: Queen in opponent's suit.
Other bids: K/Sing. in opponent's suit.
RDBL: A/Void in opponent's suit.
1.3.1.2. Suit/NT:
Pass: no control in opponent's suit.
DBL: Ace/Void in opponent's suit.
Other bids: K/Sing. in opponent's suit.
1.3.1.2.1. Suit/NT after KC limitation:
Pass: no trump Queen (or enough KC for grand slam).
DBL: to play
Other bids: CUE, enough KC for grand slam.
1.3.2. Over asking bids:

Discussion:
Why put slam conventions before the main system?
-> Because you need to know what to expect at the highest levels to plan your bids at the lower levels.

1. Introduction:
This system features some themes: giving as little information as possible to the opponents; sacrificing some sign-offs to improve game and slam auctions; major oriented transfer responses; distribution-inquiring relays only for 5-4 type hands with No/HiMiLo responses; alternative way of "natural" bidding using xfers, which allow low level checks. Template rebids and their continuations, to allow brainpower to concentrate on playing; Smart Splinters(New!) in 2 way competition; Stepping template responses in competition(New!); Smart Michaels(New!).
