+**Development after 1N 2\d or 2\h**
+Opener either accepts the transfer at the lowest level or with a maximum NT, bids 2N with 3 card support or jumps in the long major with 4 card support.
+**Development after 1N 2\s or 2N**
+The opener bids the "slot" (the bid between the 3-level of the responder's suit and the call that the responder made) if he "likes"
+his hand in terms of strength and support cards. Otherwise, he bids the indicated suit at the 3 level.
+New suit (w/o a jump) from the responder shows //shortness// in that suit.
+**Development after 1N 3\c or 3\d**
+Responder has shown both minors  3\c shows longer \cs; 3\d shows 5+\d and 4+\c.  New suits by opener show a preference for the longer suit; a bid of the shorter suit show a preference there.  Example: 1N 3\c 3\d opener prefers \d, anything else he prefers \c.
+**Development after 1N 3\h or 3\s**
+The opener shows a control bidding 3N before showing a 4-level control if his hand is slam-suitable.
+**Other calls**
+\c is Gerber
+\d is Texas (long \h suit)
+\h is Texas (long \s suit)
+====Competitive Auctions after 1N====
+If the double is for penalties (as opposed to Brozel or whatever), then we use the following agreements to scramble out of the rough.
+"DONT" escapes
+  * 2\c, 2\d, 2\h show the suit bid and a higher ranking suit.
+  * 2\s, shows \s and is weaker than a redouble, then 2\s.
+  * XX indicates that a single long suit is held.  Opener bids 2\c to escape into responder's long suit
+  * P forces a XX by opener and declares the "hand belongs to us"
+**1N - P - P - X**
+Re-double is for penalties (showing 15-16 HCP).
+**1N - P - P - X - P - P - ?**
+DONT escapes
+**1N - enemy overcall - ?**
+The general approach is to use lebensohl and informatory doubles unless the enemy overcall is specifically 2\c.
+In that case double is Stayman and other calls ignore that the double was made.
+  * Double informatory 9+ - 12- HCP typically a small doubleton in the enemy suit.
+  * 2 level competitive
+  * 3 level forcing to game or 4 level (2/2/2026: restored original agreement - minor used to be non-forcing for a long while)
+  * 2N forces 3\c and if the suit revealed
+    * is lower ranking than the enemy's suit, it is a competitive bid
+    * is higher ranking than the enemy's suit, it is game invitational
+    * If instead, responder now cue bids the enemy suit, he is asking for a 4-card major while also showing NT help in the enemy suit
+  * An immediate cue bid of the enemy suit is asking for a 4-card major and //denies// NT help in the enemy suit
+**After 1N - P - Transfer - X**
+  * Opener re-doubles to show a 4 card holding (to an honor) in the artificially bid suit and denies 3 or more cards in the indicated suit. Opener passes with fewer than 4 cards in the artificially bid suit and fewer than 3 cards in the indicated suit.
+  * Opener accepts transfer with 3 card support
+**After 1N - P - transfer - overcall - P - P**
+  * Responder bids suit under true suit to re-transfer.
+  * If the suit under the true suit is not available, then a bid of the long suit is ambiguous in terms of invitation of just competitive.
+  * He bids long suit directly to show invitational values.
+  * He bids a second suit to make a game force.
