=====After the enemy opens other than 1N=====

The defensive system is a mixture of Ghestem two-suited bids and Kaplan structure and philosophy. 
The Kaplan part consists of natural good overcalls with a new suit forcing by advancer (i.e. the partner of the 
person taking the first action for the defensive pair). In addition most jump 
overcalls are preemptive in nature.

Special situations:

* If we overcall 1\h or 1\s and the next hand makes a negative double, then the cheapest bid in the (so far) unbid major is a constructive and artificial raise of our suit.
  * Jump raises are preemptive in nature.
  * Cue bid of LHO's bid is a constructive limit raise
  * Cue bid of RHO's bid is natural.
  * A 4\c or 4\d call over a one level opening bid shows a strong Namyats 4\h or 4\s bid respectively
  * After the opponents open 2N or an artificial strong 1\c or 2\c, we play "suction"
    * Suit bids made with or without a jump show the next higher suit or the two lower suits;
    * NT bids show two non-touching suits.  In the case of a 2N opening bid, the double is used to show the two non-touching suits

The 1N overcall shows 15-18 HCP (11-14 HCP in balancing seat). The responses are the same as those over a 1N opening bid.
  
The 2-suit overcalls show 5 or 6 losers and go as follows:

Over any (natural) 1 suit bid in direct seat and in balancing seat from passed hand:
  * Cue bid is top and bottom
  * 2N is lowest two suits
  * 3\c shows the two highest suits, except when 1\c is opened.  Then the bid showing the two highest suits is 2\d.

In balancing seat from unpassed hand:
  * Cue bid is Michaels (1m-2m: majors, 1M-2M: other major and a minor)
  * Jump new suit is 15-17 good suit
  * 2NT is 18-19 points balanced.

=====After the enemy opens 1N=====

If the range of the NT is such that a 13 HCP hand is too weak to open 1N, it is a "strong" NT.  We use DONT with Paradox responses to the double.
What in heavens name is Paradox responses?  Advancer with a constructive hand, skips suits that he would be
willing to play at the next level, if that is doubler's suit.

If the range of the NT includes 13 or fewer HCP hands, it is a "weak" NT.  We use Cappelletti structure in both seats
with Paradox responses to the 2\c overcall.
