3NT: Slam try with 5-5+ in the majors
Saturday, February 18, 2012
4♣/4♦: Good hand for Hearts/Spades bidding cheapest suit is a retransfer. Kickback possible now or after retransfer
4♥/4♠: Better hand for named major but not a great slam hand
4NT: would be an off-shape hand usually 2-2 in majors
bidding 5 of a minor by responder would be exclusion key card over any bid agreeing trump.Obviously this means one cannot bid 3NT directly but must use puppet Stayman. Most hands respobder will want to do that anyways to find a 5-3 major suit fit.

1.1. Exclusion Keycard
This method does not count the Ace in the suit bid, but does count the King in the agreed trump. So, there are 4 keycards. The responses are
step 1: 0 KC
step 2: 1 KC
step 3: 2 KC
step 4: 3 KC
step 5: 4 KC
Exclusion Keycard can be used in three situations:
1) after Texas where the suit transferred to is agreed as trump. A bid beyond game asks. 4♠ after a Texas 4♥ is Kickback and 4NT is Exclusion Keycard with a Spade void
2) after a jump beyond game in a new suit where trump has been agreed
3) bidding opponents suit beyond game in agreed trump or last suit bid(does not have to be a jump) and agrees last bid suit if trump has not already been agreed.
The exclusion keycard bid is at the 5-level except for 4NT over Hearts which is a void in Spades.
5♣ is also exclusion keycard where trump is Diamonds and otherwise qualifies even though below game.
