Fourth Street is the fourth round of dealing in stud poker, where the second up‑card is revealed.
Explanation. In stud games, after third street (two down, one up), the next face‑up card is dealt; that stage is Fourth Street. The term simply follows the order of streets (third, fourth…). It triggers a betting round and helps players assess visible strength. Knowing each street by name improves tracking of progression in stud variants.
