Chess960 puzzle no.19

One of the most incredible openings I have ever seen in chess960 after only eight moves. You would think clearly white is better but white has some big weaknesses even though black's king is exposed.

SP650: Black to play (castling all sides/colours still possible)

Which side do you think is better in this position?

Answer bottom left corner below

Answer: black is better because of serious weakness on e2

(checked with Stockfish engine)

8)     ...Nf4  threatening bishop and fork on e2

9)Bf3  ...     defending fork

9)     ...Nd4  threatening e2 fork and attacking a4

10)Nb6+...Kb8  quiet move before the next wave of attacks

11)Ng3 ...     defending fork and developing

11)    ...g5!  threatening to undermine Bf3 and preparing Qg6

12)Nxa8...g4!  undermining e2 defense

13)Qf1 ...      stepping out of fork attacking a6

13)    ...Bb5  black actually does a bit of defending!

14)d3  ...     guarding c2 against Qg6 and attacking b4

14)    ...gxf3 capturing material

15)gxf3..      else queening threat!

15)    ...Qg6  threatening mating line beginning Nxc2!

white is completely lost
