# What is the rationale for a "forcing" 1NT with a range of 6-12 points?

First of all, my understanding is that no trump bids should be made within fairly narrow point ranges (2-3). Therefore, "6-12" looks like an awfully wide range for a single no trump bid.

Also, I feel that there is a world of difference between forcing and non-forcing. I prefer to use a 6-9 1NT bid as nonforcing, and opener can pass it there with a minimum. I would use a "two over one" sequence for 10-12, the upper part of the range.

So why do some bidders prefer such a wide "forcing" 1NT range of between 6-12 high card points instead of the above?

• Do you want to miss game when opener has a big hand and a fit for your lower ranking suit which is their second suit? Being +110 in 1S when you should be +620 in 4H costs you 11 IMPs. Being -100 in 2S when you should be +90 in 1N only costs you you 5 IMPs. Dec 24, 2022 at 22:21
• @AlexanderWoo: I fixed the question by asking why people prefer a forcing 6-12 range instead of breaking it up into two ranges, 6-9 (non-forcing) and 10-12 forcing. Even a big hand can rebid with a non-forcing 1NT (but a "small" one isn't forced to.) Will you remove your downvote (if it is yours) and/or address my new question? Dec 25, 2022 at 23:22
• the answer is that most experts now prefer to play a 2/1 response as game forcing, and hence the invitational hands have to go in 1N. People feel that the gains from 2/1 being game forcing outweigh the losses from putting 10-12 hands in 1N. Dec 26, 2022 at 3:43
