The Windmill: a theory course

Repeated checks can let another piece capture between checks. Preserve the checking pattern as you calculate.

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

• Repeat the Checking Pattern — Alternate direct and discovered checks.
• The Bishop-Rook Battery — Coordinate the bishop and rook for repeated checks.
• Set Up the Checking Pattern — Prepare the checking pattern before sacrificing.
• Choose Captures Between Checks — Choose useful captures without breaking the checking pattern.
