Jacoby 2NT (Swedish: Stenberg 2NT) is a bridge convention in which a bid of 2NT over partner's opening bid of one heart (1 ♥) or one spade (1 ♠) shows a hand with both opening strength or better - normally at least 12 HCP or a hand meeting the "Rule of 20" criteria, and; at least four-card support for opener's major suit.
The Jacoby transfer, or simply transfers, in the card game contract bridge, is a convention in most bridge bidding systems initiated by responder following partner's notrump opening bid that forces opener to rebid in the suit ranked just above that bid by responder. For example, a response in diamonds forces a rebid in hearts and a response in ...
In response to a 2 ♣ opening, the 2 ♦ response is the "waiting" version of that response. In response to a weak-two opening, RONF ("Raise Only Non-Force") is used. The Jacoby 2NT is used to show a game-forcing raise of a major suit with four-card support. Negative doubles are used through the level of 2 ♠. Fourth suit forcing is used.
The first drawback is that the weaker hand occasionally will end up declaring a contract with a trump fit in the major suit of the response. (Note that a transfer following opener's rebid of 2NT over a response of either 2 ♥ or 2 ♠ may be to the suit of the response. Such transfers cannot achieve the objective of making the strong hand the ...
An opening bid of 2NT shows 20, 21 or 22 HCP. If responder has 13 HCP, then a small slam looks certain (13 + 20 opener's minimum = 33) and should be bid; If responder has 11 or 12 HCP, then a small slam is a possibility but more information is needed about opener's hand before it should be bid. This is where a quantitative bid should be made.
In contract bridge, Bergen raises are conventional treatments of responses to a major suit opening in a five-card major system. [1] Developed by Marty Bergen and first published in April 1982, [2] Bergen raises are based on the Law of total tricks, a hand evaluation concept which states that with a combined nine trumps in the partnership one should compete to at least the three-level ...
Normally, a strong two bid is forcing for at least one round. Possible responses are: A 2NT response is negative, showing a weak hand (six points or fewer in Standard American). All other responses are positive; in Acol these require 8 or more points or an Ace-King, i.e. 1½ quick tricks. Raise partner's suit with 3-card support.
2/1 game forcing (Two-over-one game forcing) is a bidding system in modern contract bridge structured around the following responses to a one-level opening bid: a non-jump response in a new suit at the one-level is constructive and forcing for one round, a non-jump response in a new suit at the two-level is forcing to game, and
