I play a much broader variation of Forcing NT (0-18) to show 1. A weak hand with no fit (next round new suit or pass partner's new suit) 2. An invitational hand with 2 card fit (next round cheapest return to original suit) 3. An Invitational 3 card fit (next round jump support openers suit) 4. A game forcing 3 card fit 13-15 (next round bid 3nt over a 2 bid, make a slam try over a 3 level response) 5. A slam trying 3 card fit 16-18 not fit for an immediate slam try and lacking a good 2/1 suit to bid (jump into new suit next round or sign off in 4 spades, or make other slam try) It is very important that my partner never pass the Forcing NT bid since one of its uses is to escape the misfit.
