King & Two Bishops vs King: an endgame course

Coordinate both bishops and the king to restrict the enemy king, then deliver mate at the edge.

5 lessons, each followed by its own puzzle drill, then 10 themed puzzle packs.

• The Two-Bishop Wall — Use both bishops to restrict useful diagonals.
• King Joins the Attack — Bring the king close enough to cover escape squares.
• Force It to a Corner — Reduce the king’s space toward the edge and corner.
• The Waiting Move — Choose a safe waiting move without causing stalemate.
• Corner Mate — Cover the escapes while one bishop gives the final check.
