Can someone analyze this?

- didn't push the c pawn to support d pawn (missed rook c1 after castle)

- Move 18 - Nc5 caused uncoordination. 19 should've played Bb6.

- Attack weak space - f6.

These are the key mistakes I made. Thanks for the good analysis fellas. I'd kinda like to see if Korch can see any further ones or if Maris made any.

After 9.Bb5?! (instead of 9.0-0 with slightly better position) Kf8? (instead of simple 9...Bd7 with equal position) your position was better until 19.Nb6? - after that your position was lost. You should have play 19.Bb6 Qf8 (black has nothing better) 20.Nxe5!! axb5 21.0-0 with strong attack for piece.

Also you could play 18.d6 Nc6 19.0-0 with advantage (instead of 18.Nc4).

Thanks for that. I'm rather suprised I kept a winning position to move 19. That was an outward blunder 🙁

"with strong attack" does not means "winning position" - don`t forget you had to sacrifice piece for that attack.
