HoH 2 question

[kimos123]

In page 210 the problem 9-22
after the flop he assume that both players called with low pair. the BB doesnt need to have anything he didnt call he just checked. and he assume that not betting here is not good.

could someone please explain to me if i am wrong in this:
the BB have a garbage hand. player B limped with a low pair, so the A on the flop is a scared card for him since he will put you on A suited or something like that and therefore betting is good?


and the second question:
assume you have 88 will you still not bet that flop?

my final question:
if you have no pair no draw and they checked to you, will you bet?

regards,
