   * New suits are natural and game forcing unless the call qualifies as a relay. The hand is typically 5332. Don't do this with a singleton.
   * 2N is a relay if opener's second bid is 2\S; it is a natural limit bid if opener bid touching suits in a descending (higher ranking suit bid first) Canapé; it is a game force in the suit displaced by the relay otherwise.
   * Jump shifts into a new suit show a solid suit (AKQ109x)
+  * A jump bid back into opener's first bid suit is a natural GF (4-card support); typically this is a result of an opponent's overcall, but in the following auction (only) ... 1\s 1N 2minor 3\s shows a \S GF (4-card support) and a long \H suit (5\+)  and is a slam try.

-The call of 2N is a game force in the suit opened. Responder promises Hxxxx of trumps. Opener rebids his long suit. A 3N bid by either (except if 1Diamond is opened) is a trump asking bid: the response shows the number of honors (step 1 = no honors; step 2 = 1 honor etc.). Later development is cue bidding

 =====How responder shows a good suit and game forcing values=====
@@ Line 171: / Line 176: @@
 Most responses are the same. Jump shifts are an exception. They show a 4 card fit and a source of tricks (flower bids). A jump shift is forcing to 3 of opener's suit
+A second relay by a passed hand is obviously not a Game Force, but does indicate a hand greatly improved by opener's second bid (usually).  The rules are:
+  * Cheapest new suit bid is a relay
+  * Cheapest NT is never a relay ... is natural
+The rationale is that a new suit is never needed for a natural bid, with a suit worth bidding, the passed hand would have bid it immediately.  Added and agreed  --- //[[John@Kinn.Org|John Kinn]] 2017/06/23 09:15//

 Now that a jump shift is sensibly a forcing to game bid to show a good 6 card suit, we can develop an intelligent follow up. This is it:
