Precision Pass 2.1

This is the strong pass equivalent of Precision. Pass is not forcing, so theoretically a board can be passed out.
1 is the fertilizer bid and is made on all bad hands.

Opening bids in 1st and 2nd seat

This is the garbage opening bid that is used in every strong pass system.
  • 1NT: Forcing asking bid, Romex style
  • 2x: To play
  • 2NT: 0-4 losers, 2-suiter

    If 1 gets doubled, pass suggests playing there, redouble suggests playing somewhere else, and anything else is natural.

    1 - 1NT - ?
  • 2: Second negative
  • 2: Maximum 4-card
  • 2: Maximum 4-card
  • 2: Maximum, no 4-card major
