It is way too hard for black to find the best move here in a blitz game?

Because you asked I saw it immediately I think. :)

haha cool , so what is the best move here ?

Ba3?

very good man :))

sick tactic that might actually be useful to know ;)

Well, it‘s useful to know some tens of thousands of chunks.

By the way, I played often this sharp line with Black. Not few (including GMs) fell victim to it and played the very „natural“ blunder 12. ... Nc6??

Nice one , Thank you for sharing this experience

can trade white bishops and press white squares with the queen

The variation is hot! I had my successes with it but I never played 12. ... Nc6 of course. ;)
