I was GMing and player was trying to get past a Troll so he did a defy danger move with dex. he rolled an eight. so I said, ok, the Troll misses you, but you don't get by him.

The player said that 7-9 should be mixed success so he should have gotten at least partially by him, or should have have offered a hard bargain like you get by him, but you take damage, or you stay where you are and take no damage.

I was thinking I was offering the "worse outcome" option.

how do you treat this?
