     * 2\H: 15 HCP, artificial
     * 2\S/3\C/3\D/3\H: 16\+ HCP, cheapest 4 card suit
+===== Roman Keycard Bids =====
+==== Responses to 4NT ====
+  * 5C: 0 or 3 KC
+  * 5D: 1 or 4 KC
+  * 5H: 2 or 5 KC w/o the trump Q
+  * 5S: 2 (or 5) KC w/ the trump Q
+  * 5N: even number of KC and a useful void
+  * 5x: odd number of KC and useful void in x
+==== Continuation ====
+Further asking bids from inquirer:
+  * After a response that does not tell about the trump Q (0/3 or 1/4 KCs):
+    * 1st (non-trump) step: Q ask
+    * 2nd (non-trump) step: specific K ask
+  * After a response telling about the trump Q (2/5 KCs):
+    * 1st (non-trump) step: specific K ask
+=== Responses to Q ask ===
+  * lowest trump bid: no Q
+  * any other: have the Q. If possible we try to show lowest specific K (below 6trumps) as well.
+    * E.g. with \h trump after 4NT-5\D-5\S:
+      * 5N: has \hQ, no minor K, may or may not have \sK.
+      * 6\c/\d: Has \hQ, lowest specific K
+      * 6\h: no \hQ
+    * With \s trump after 4NT-5\C-5\D:
+      * 5\s: no \sQ
+      * 5N: has \sQ, no outside K
+      * 5\h, 6\c/\d: has \sQ, lowest specific K.
+    * With \d trump after 4NT-5\D-5\H:
+      * 5\s, 6\c: has \dQ, shows lowest K
+      * 5N: has \dQ, no black Ks, may or may not have \hK.
+      * 6\d: no \dQ
+After a K showing response, if inquirer bids a new suit, it asks responder to bid the grand if he has that K, too. Over an ambigous 5N the next non-trump step asks to bid the grand if responder has a K.
+=== Responses to specific K ask ===
+  * 7 trump shows 3 outside Ks
+  * lowest trump shows no outside Ks
+  * a suit shows either that K or the other 2.
+    * for example given \h trumps, after 4N-5\d-5N:
+      * 6\c: \CK, or both \D and \S Ks
+      * 6\d: \DK, or both \C and \S Ks
+      * 6\s: \SK, or both \C and \D Ks (inquirer must be careful!)
+  * 5N shows the lowest K one step over the trump suit
+      * for example given \d trumps, after 4N-5H-5S:
+        * 5N: \HK
+        * 6\c: \CK or both \H and \S Ks
+        * 6\h: both \C and \S Ks
+        * 6\s: \SK or both \C and \H Ks
+==== If opponents overcall 4NT ====
+We play D0P1/R0P1:
+  * Double/Redouble: 0 or 3 KC
+  * Pass: 1 or 4 KC
+  * 1st step: 2 or 5 w/o the Q, etc.
+Continuation is as before.
