Good position plus tactical oversight = loss
This is a game where I played well positionally, failed to find the right way to open the queenside, then missed a tactic from my opponent that ended the game rather quickly.

(I've mixed up "Black" and "White" when mentioning bad bishop and f5 and d5 in one of the annotations)
On 29. Nf6+ I was seeing the ghost of Kf8 Nh7# if my knight had still been on e7. I also missed the pin of the f7 pawn after Qh7+.
