White to play.
It's my move, and I have a good attack on the go on the queenside against the Black king. I was looking closely at 19. Nc6 with a decisive fork on King and Queen, but this is prevented by the black Knight on e5. So... I thought, I would play 19. f4, kicking the knight away and then play 20. Nc6+ - I could see his reply 20 ... bxc6 could be met by 21. Qxc6! and mate is unavoidable on either a8 or b7.
Great! But then I realized there was a major flaw in my analysis... What is the flaw and what would you play instead?
