2NT

This bid indicates that the bidder has a balanced distribution of suits and a very specific number of High Card Points.

The suit distribution of the hand can be in either of the following three patterns5, 3, 3, 2 In any order
or
4, 3, 3, 3 In any order
or
4, 4, 3, 2 In any suit order

However the point count is different and depends on whether the bidder is responding or opening 2NT.

As a responder in both ACOL and Standard American 2NT means 10 -12 HCP

As opener in Standard American 2NT is 20-22 HCP

As opener in ACOL 2NT is 20-22 HCP

The Acol Bidding System

*If you live in the UK, Ireland, Australia or New Zealand Acol is the most widespread system Acol has the following characteristics:
  • It is a natural system: most opening bids, responses and rebids are made with at least 4 cards in the suit bid, and most no trump bids are made with balanced hands.
  • It is a four-card major system: only four-card suits are required to open 1 or 1, unlike Standard American and many other systems where five-card suits are typically required.
  • It makes extensive use of limit bids: limit bids describe the hand so closely, in terms of high card points (HCP) and shape, that the one who makes the limit bid is expected to pass on the next round, unless partner makes a forcing bid.
  • Understanding and correct use of limit bids and forcing bids is fundamental to applying the system: all no trump bids below the level of 4NT are limit bids, as are all suit bids that merely repeat a suit already bid by the partnership; changes of suit may be forcing or not depending on the approach bids.
  • The level of the 1NT opening bid influences other bids: the normal choice is between a “weak no trump” (12–14 HCP) and a “strong no trump” (15–17 HCP).
  • All 1 of a suit opening bids then promise at least 4 cards in the bid suit
  • Notrump follow-up conventions include Stayman, Jacoby transfers Blackwood and Gerber Convention.
