One Notrump Forcing 6-14

In a Nutshell

The forcing 1 NT response to a major has been around for ages, typically with a range of 6-12 HCP; and some players treat it as semiforcing (is that like half pregnant?) because of the upper limit. To me, a bid is either forcing or not; and if forcing it should be put to broader use.

Therefore, I extend the range to 14 HCP and incorporate special rebids by responder to show 13-14. Most innovative is that any jump shift rebid is a “value raise” of opener. Another advantage of the 6-14 range is that a 2 NT response (natural) shows 15-17 HCP (like a 1 NT opening) which facilitates slam bidding decisions.

Details

The 1 NT response to 1 H or 1 S shows 6-14 HCP (it may be less with a trump fit) and denies 4 spades after 1 H. It is forcing.

*A value-raise shows normal trump support for opener’s suit, usually with the king or queen in the suit bid; further, if just one unbid suit remains, this implies no secondary honors in the unbid suit.
