@MSC:
I'm no expert on this line at all, but the white pawn on a3 looks a bit weird. Maybe it's better to go for a quick b5-b4 to try to abuse that? castling kingside is also an option for you I think. You're castling into an attack ofc, but it seems quite slow for white. You haven't made any weaknesses on your kingside, the classic break is playing for g6, but that takes a while to get to.
Just some example line to give a general idea of what I'm looking at:
11...0-0 12.g4, b5 13.g5, Ne8 14. h4, b4 15.axb4, Nxb4.
Looks like your attack is fast enough to give white some troubles.
You have ideas like 16...Rxc3, or 16...e5 17.Nb3 Ba4, or 16...Qa5 17. Nb3 Na2+, or 16... d5. Not claiming that those are winning or sth, but you're getting all kinds of open files and concrete ideas allready, white is still busy pushing pawns to start to open up your king.
I was on graduation trip previous week and when we had time we also played chess. Some nice games came out. Unfortunately lost both of them.
Here's the 1st round. Time control was 60|30 (40) + 15|30.
