We discussed in the first perek the rule of אתי אוירא מהאי גיסא ומהאי גיסא ומבטלה -When the middle panel is smaller than the space on both sides of it the panel is negated.
How does adding panels six tefachim wide in middle of the פסי ביראות according to ר”מ help reduce the size of the opening when the gaps between the panel and the פסי ביראות are larger than the panel?

See how the תוס’ ישנים (in brackets) gives a different answer from Tosfos.
Learn ח’ ר”ן “ארבעה (attached) who gives a very different explanation.
How wide do the panels in between the פסי ביראות need to be?
According to Tosfos why is the bracha on Sukkah recited specifically on eating or sleeping inside the Sukkah?
Learn רא”ש ס’ ג starting from ומה שאין מברכין על הסוכה בשעת שינה who quotes ר”ת who says the minhag is that a bracha on the Sukkah is only recited when eating inside the Sukkah.
Bring a proof whether the Rosh agrees with this minhag.
According to the conclusion of the Gemara that a group of three can enclose a large area as much as they need as long as there is not an extra 2 סאה of unneeded space.
What is the halacha of a group of three enclosed 6 סאה but only needs 4?

Questions:
A vertical fence that has gaps is a valid mechitza if it is עמוד מרובה as the gaps are considered פתחים – points of access. What is the logic to entertain allowing horizontal gaps?
Our Gemara is uncertain whether we consider עומד מרובה משתי רוחות a valid mechitza. How is this consistent with the גמרא דף י עמוד ב which seems to conclude it is a valid mechitza?
