Partner CANNOT pass. That's why it's called the Grand Slam FORCE
And it's inane to think that a 1♠ opening wouldn't contain
at least the A or Q♠
Yeah Justin, how can you not know this convention? Jeez, thought you were supposed to be a good player. All the top players are using it

Barely a day goes by when I don't whip out GSF. How else can you get to grand when partner opens a weak 2S and you have AJx xxx xxx xxxx? It really sharpens your card play too, I seem to be playing 5NT one hand in six, it feels like whenever I play 3NT now that I *have* to make 11 tricks - it just feels weird otherwise.
