Commentary for Sukkah 13:17
דהא את הוא דאמרת סיכך על גבי מבוי שיש לו לחי כשר
for it is you who ruled that if one placed skhakh over an alleyway which has a side-post it is valid?
Rashi on Sukkah
Like an open alley - so that the two walls [are erected] opposite one another.

Rashi on Sukkah
In any place that he wants - for look, there are four [unattached] ends [of walls] and at any of those ends that he wants he may build [the third wall].
