Editing 2/1 game forcing (section)

==1NT response to major suit opening==
Because the two-level responses are stronger than in [[Standard American]] bidding, the response of 1NT is [[Forcing bid|forcing]] for one round and is used (among other things) for weaker hands containing low-ranking suits.  Since the 1NT response is forcing, hands with a three-card limit raise can start with 1NT and later jump-support partner.  See [[Forcing notrump]] for additional details.  Some pairs play a variant in which the 1NT response to 1{{Hearts}} or 1{{Spades}} is [[Forcing notrump#Semi-forcing notrump|semi-forcing]].

Since opener has been forced to rebid on hands which he might otherwise have passed, he may have to rebid in a new suit with only three or even two cards.
