Changing advantage (At least I think so ;-))

Hi

This is a chess 960 game (3 days per move) that I just played. I'm not really sure where to post it, because I won, but I have a little question though.

And, I really like this game because at least for me, it felt like that first I was winning, then my opponent, and at the end, it changed again.

What do you think? And what would have you done in move 20?

i think you need to learn how to set the board up correctly?

i thought rooks belong in the corner

No, the position is correct. It's a chess 960 game:

I might have given bxc6 a try on move 20, considering the positions of your queen (aimed at g7), the bishop (ready to deliver a check if a support is present) and the rook (can deliver a deadly forked check at c7 with your pawn if you are able to battery your rook with your queen and black moves his queen away).

Capturing with the pawn simply offers more open possibilities.
