|Black to move|
There are 3 PoPs: e6, f4 and f1
But I couldn't focus on them, and started to dabble around with moves like 1.Qc4, 1.Qc5, 1.Rc5, 1.Qxf4, 1.Bxe6, 1.g6, 1.Bb7. Even fxe6 was considered a few times, but I could not make it work.
Yet, if my mind was only disciplined enough, and would follow the system I described, I would soon have found the answer. I must unlearn the habit of trial and error.
