Mate with B + N vs. K

White to move and win.

Basic Guidelines:

  • Keep King in opposition or a Knight's move away from the opposing king.
  • Force the opposing King into a corner of the same color as the Bishop.
  • Use the Knight to cover flight-squares of opposite color of the Bishop.
  • Use the Bishop to create Zugzwang positions.
