right hand chord progression help?

[izzy1]

I've been looking and studying music theory for a while now. I must say it gets confusing most of the times. The questions i am asking is how does the right hand connect to the next chord in the right? the transitions? also, using inversions help to smooth the transitions but sometimes chord inversions aren't used. lastly, how far is too far of a jump between transitioning from one chord to another? a whole tone? I have some examples to demonstrate what im talking about:

1. C minor to Bb major to Bb major again to F major. No chord inversions, why? and the Bb major doesn't change why? is this on purpose? is there a rule?

2. the "jump" between the chords. The G augmented chord to Db major 7. I was told that it was too far of a jump but obviously it's not but im trying to figure what is too far and what are the rules for it? im sorry i forgot to put the time.

is there a rule?

No
Does that answer your question?

Using inversions to smooth transitions is optional and not necessary in all cases.

A lot of the chords he plays are polychords i.e. C minor with an Ab in the bass is not C minor, it's actually Ab major 7. If you listen to him he says what chords they are.
