This is a site on my bridge bidding system,
Siege.
Why use a short club with transfer responses?
1♣ opening - natural or balanced
1D opening - 4+cards, unbalanced, may have longer ♣
1♥/♠ openings - 5+cards, 2/1 GF
1♥/♠ openings - 5+cards, light 2/1 responses
1♥/♠ openings - 5+cards, 2♣ relay (under construction)
1NT - 10-13 1st seat NV, otherwise 14-16
2♣ opening - "Trebuchet", either a weak 2 in D or a strong hand
2D opening - "Mini-Multi", a weak hand with a 6 card major
2♥ and 2♠ openings - "Dutch", weak with a 5 card major and a 4-5 card minor
Openings in 3rd+4th seat
Coping with interference (transfers in competition)
