N has shown only 10 pts by his 5S and 6C bids. So he must have D-Q and J for his 14-15 pts. S loser will go on D-Q and J.In case your are very pessimistic, you pass 6C bid.

* Warning: Be careful before making 2nd/3rd relay on minor suit opening, i.e. whether you are prepared for crossing 3NT level.

Possible replies can be as follows:-

  1. 3D, if 6 cards Dia, then play 5D
  2. 3H, if 3 cards H, then play 3NT
  3. 3C, if 3 cards C, then play 5C
  4. 3NT, if 2 card H & C, play 4C,5C or 3NT hoping H-K or A with N.
