Choice of suit openings

The most descriptive 1NT takes priority over all suit openings.

  • 5+, 5+: Always open the major suit
  • Other 5+ 4+: Open the longer eligible suit (MAX 2 must contain 6+)
  • Between 4-card suits:
    • > > for the first two seats
    • > > for the last two seats

The precedence of 4= depends on the seat. If the seat never opens 1 for (4333), 4= come before 4=.
