Strong Diamond

The Rugged Diamond System

The Rugged Diamond takes it's inspiration from Fantoni and Nunes' Fantunes System but there is a great deal of involved and research involved in developing the system.  The opening bids are as follows:

Bid

1♣

14-17

Artificial non-forcing, no five card major.  This is the unlikely star of the system.  Only when your familiar with all the sequences are it's true strength revealed.

Artificial.  All strong hands are opened one diamond, the only forcing opening bid.  The continuations are comprehensive and deal with intervention in new ways.

12-17

5+

These are five card majors but I include novel artificial two level responses.

1NT

9-13


No good five card major, no void. This opening occurs about 27% eating up bidding space and creating real problems for the opponents.

2♣

7-11

0+

Five card major weak twos.  Two clubs shows five hearts, two spades shows five spades.

6-10

6

Six card weak twos.

2NT

6-8


A good pre-empt in a minor
