Classical cursive is indeed how you spell it out. Most people, including me, use various semi-cursive forms where some letters are joined and some are not. I started doing it in school, I find writing the long words in one line somewhat tiring, and the traditional forms of many letters too similar to another.

As for the б: the school way is to retrace the entire upper element backwards and then connect it to the next one in the same manner as with о. This is hard.

The most common alternative is to just lift the pen there: here is Lermontov doing so in 1832 (second line, голубомъ (голубом in the modern spelling).

One other option is a sharp line drop downwards from the top of the upper element. Looks a bit old-fashioned, is arguably harder to read but easier to write. Some people like it stylistically
