===== Ideas we should consider =====

  - We need a good structure over 1M - 2NT
  - 1!D - 2!C -- http://www.gg.caltech.edu/~jeff/system/kokish.html perfect for weak NT

===== Introduction =====

We play an light initial action 2/1 GF system, with 1NT forcing and weak notrumps in most positions. We open most UNBAL 10HCP hands, and most 11HCP BAL.
