Dwayne hoffman in the alert thread said: FSF I refer to after a G/F is established and three different suits have been bid and unsupported. To me, makes things easier on pard - if you got the fourth suit covered and you can't support a game bid in his/her two suits, bid NT to tell the good news. I also agree that they are many treatments that are misconstrued in overtone. As this seems to warrant a new topic, i've started one. This is not at all what I think of as FSF, yet another eye opener for me. Another nuance to discuss first. In my circles FSF establishes the game force (some say for one round but that's wimpy). And there are very few auctions that fit the mold, yet the occur surprisingly often. always uncontested. 1c-1h-1s-2d ... 2d is fsf to game and says nothign about diamonds, partner is expected to bid 2nt with a diamond stopper. Show 3c heart support, or rebid clubs. This is one of the most common fsf auctions. 1c-1d-1h-1s --- the exception, we don't treat this as fsf, just a second suit. The corrolorry is, if as responder you need to force to game, the auction should go 1c-1d-1h-2s! 2s is fsf and says nothing about spades. I wonder what the standard treatments are of this convention, and what the pros-cons for variances are.
