IDAK: Instant Destroyer and Killer

If RHO opens or responds to an artificial club opening,

1) A suit (or NT) bid shows the suit above it. One-suiters bid as high as is safe. Two-suiters are shown by transfering to one and bidding the other.

2) 1 shows a 4333 hand (any four carder) or any number of spades.

Responder bids his best suit at the highest safest/most practical level. With the spade hand, overcaller rescues...

3) A jump in spades shows both minors. A NT advance asks for the better minor.

4) Double shows any three suited hand. If advancer has

• a) a one-suited hand, advancer bids the suit below the real suit at any level. With support, overcaller bids the suit else overcaller passes. For example 1 x - 1 (spades)
• b) a preemptive hand with both majors, advancer bids 2NT
• c) a preemptive hand and both minors, advance 3NT or higher NT
• d) 9+ points and two suits, advancer bids 1NT and the suits are bid up the line

[** HWE note: I'm not sure if the info on (4a) is wrong or not. My other set of notes say that advancer bids TWO suits below their own.]
