i can answer this. the answer is that you cant have a stud table with 9 players, stud is played with 8 players maximum, but yet there can still be problems because 7x8 = 56

...im guessing that 8 handed stud, which is what most sites play, depends on someone folding a hand
edit: it would be fun as an experiment for 8 of us to sitdown at a stud table and check a hand through, just to see what happens....
