Does it ever happen to you? I mean you look for a position almost endlessly, but still you can’t find the correct moves. It is not the first time this happened to me and I am afraid it won’t be the last time either. See the diagram.
White was already facing a lot of problems. But with 30. f4?? he turned a bad position in a losing one. How can black obtain a winning advantage? Solution…
PS. I failed to find the correct solution 😦
I found this puzzle on ChessTempo
