Finally, I got one right (1 and 2 for the series, now). My key to success was the thought that I had to find a way to remove the White Knight from its strong outpost, and that the black-square bishops were not strong for either side (there were already a lot of pawns on black squares and if I could fix the pawn structure to keep pawns on the black squares, then White's bishop wouldn't be much value to him). From those two observations, I found the right moves.
