what does it take to get a brilliant move!

I have 21 brilliants it's not hard, just play naturally. (I got 3 in one day once, and 2 in one day like a month later)
Anything up to and including 'best' move is objective and valid. Anything beyond that is subjective and meaningless.

That's because you haven't made a brilliant and are crying about it.

One question...
1. What is the difference between a great move and a brilliant move?
2. Do you need to have premium for/to get a brilliant move or non-premium players can get it too?

Brilliant moves tend to involve things like sacrifices. No you don't need to be premium. Here's an example of a game with two brilliant moves (at least when I run the analysis) despite me not having premium

Brilliant moves tend to involve things like sacrifices.
Instead of "tend to involve", the truth is that sacrifice is the key element.
"Brilliant move" = " a sacrifice that is good".
and yes @magipi is right
