      * 3\S/NT: Long \D (4144) / long \H (4414), again by rank
    * 3\S: Setting trumps, not minimum
 
===== Namyats =====

A 4\C or 4\D opening shows a self-sufficient \H/\S suit, and 8/8.5 tricks unvulnerable/vulnerable.

We also play it as an overcall after opponent opened a suit on the one level: e.g. 1\H-(4\D)

===== After strong 1C =====

==== Kokish 2H ====

  * 1\C-1\D-2\H: Either a strong hand with a \H suit, or a strong balanced 25\+ HCP hand.
    *  2\S: Responder would bid it with almost any hands
      * 2NT: 25\+ hcp, balanced hand. System is on, same after 2NT opening.
      * Any other: Strong \H hand, natural continuation.

==== Extension to control responses after 1NT ====

  * 1\C-1x (forcing, natural)-1NT: Control asking
    * 3x: 0-2 controls, 7\+ card suit
    * 3y: 0-2 controls, at least 5-5 in the two suits.

==== Extension to strength showing responses after 1NT ====

  * 1\C-1\S-1NT
    * 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.
