Default principles
After 1♣ responder will respond 1♦ with any positive hand. 1kl - 1sp covers all balanced hands - also all 5332 hands (and 4441) 1kl - 1hj: at least 5+4+ 1kl - 1N: at least 5+4+ 1kl - 2kl/ru/hj: Exactly 4sp + longer other 1kl - 2sp: 5+5+ in mi So all responses are 2-suited, except 1♠ (Balanced or single suited) - If 6-card Ma and bad minor it can be treated as single suited)
Offensive bidding
____________________________________________________________________________
“The bidding system you use is only a small, even very small, factor of your bridge success.
You don’t win tournaments by using fancy bidding systems but its much more fun!”
_________________________________________________________Meckwell____________
 
In general, all unbal hands with 14+good (or decent) hcp and a nice 5+crd suit and all bal hands with 17+hcp opens 1♣.


“If early in the auction you must either overbid a bit or underbid a bit, e.g. by choosing between openings bids, always choose the overbid. This will eliminate all future bidding problems as you already have done justice to expressing your value

RCK & RCK-exclusion 1430
 
1. step (5♣): 1-4 aces
2. step (5♦): 0-3 aces
3. step (5♥): 2 (or 5) aces, no trump Q
4. step (5♠): 2 (or 5) aces and trump Q
5. step (5N): Odd aces (1 or 3) and a void somewhere
6-in-a-suit: 2 aces and void in the bid suit
6-in-our-trumpsuit: 2 aces and void in a higher ranking suit
 
After 1st Step (5♣) or 2nd step (5♦) the relay-bid is a trump-Q ask.
 
 
4N followed by 5N guaranties all aces and is a grand slam invite. Bid a not shown control or bid 6 in the agreed trump-suit without any extra. Bid 7 with very good cards
 
If the earlier bidding has denied a 1st or 2nd round control, you can over 5N bid a suit with 3rd round control – Q or xx.
 
If we are passed 4N (opps maybe preempting at the 5-level), and you would like to ask for aces, then use 5N.
 
Same step-scale after RCK-exclusion
