If he was Mekadesh her at the Chupah (and not before, there is no concern for Zenus during Eirusin), these 'fines' do not apply (he may marry on any day).

They say that R. Matanyah did so to his daughter (she married on a different day, for the Chasan was Mekadesh her at the Chupah).

Question: According to R. Lazar, in a place where Beis Din judges every day, and in a place where Beis Din does not judge at all, she should marry any day!

Answer: [Even in such places, she marries on Wednesday,] lest the time of Wednesday be uprooted.

Question: Let the time of Wednesday be uprooted (since the reason does not apply)!

Answer: Even [R. Lazar] holds like the reason of Bar Kaparah. Bar Kaparah taught, it is because Brachah is written [in Ma'aseh Bereishis] on these days.

Question: She should marry on Sunday, and [if he has Ta'anas Besulim,] he will go promptly to Beis Din on Monday!

Answer #1: It is lest the time of Wednesday be uprooted.

Answer #2: It is like Bar Kaparah taught. Bar Kaparah said, it is because Brachah is written on these days.

These [answers] agree that she may not marry on Erev Shabbos, and not on Motza'ei Shabbos;

[She may not marry] on Erev Shabbos, due to Kevod Shabbos (lest people not have time to prepare for Shabbos, or come to be Mechalel Shabbos - PNEI MOSHE);

Opinion #1: And not on Motza'ei Shabbos - Talmidim say that this is due to toil (Chachamim wanted him to toil for Seudas Nisu'in. He will not toil before Shabbos.)

Opinion #2 (R. Yosi): It is due to Kevod Shabbos (lest amidst preoccupation with the Nisu'in, he will come to do Melachah to prepare for it before Shabbos ends).

Support (for Talmidim - Beraisa): Why did they say that a Besulah is married on Wednesday? It is in order that a man will prepare needs [of the Nisu'in] three days, one after the other.

(R. Ba bar Kohen, to R. Yosi): R. Acha said in the name of R. Yakov bar Idi that it is forbidden to be Mekadesh a woman on Erev Shabbos, i.e. to make Seudas Eirusin, but one may be Mekadesh [without a Seudah].

(Shmuel): One may be Mekadesh even on Tish'ah b'Av, lest someone else [be Mekadesh her] before him.

Question: Shmuel contradicts himself! There he said "Elokim Moshiv Yechidim Baisah...", "b'Moznayim La'alos Hemah me'Hevel Yachad" (Hash-m makes Zivugim before a person is born), and here he says so?!

Answer: Rather, it is lest someone else [merit to change the decree and be Mekadesh her first] through Tefilah.

Remark: Even [if another merits to be Mekadesh her first through Tefilah], he will not keep her (he will die or divorce her, and she will marry the one decreed for her - PNEI MOSHE, from the RAN).

(R. Chizkiyah citing R. Chiyah citing R. Avahu): It is forbidden to judge monetary cases on Erev Shabbos.

Question #1 (Mishnah): (Capital cases may be decided to convict only the next day.) Therefore, we do not judge, on Erev Shabbos or Erev Yom Tov, capital cases.

Inference: We may judge monetary cases [at these times]!

Question #2: R. Chiyah's Beraisa explicitly teaches so! We may judge monetary cases on Erev Shabbos, but not capital cases.

Answer: Here (R. Chizkiyah) teaches the practical Halachah (it is forbidden mid'Rabanan). Here (the Mishnah and Beraisa) teach Torah law (it is permitted - KAFTOR V'FERACH 12, PNEI MOSHE).
