combinations of 3 defensive pieces, or any combination of a minor piece plus a defensive piece except horse + elephant. This combination draws against all 4 defensive pieces. A horse plus an advanced soldier(on the 8th or 9th rank) draws against either combination of 3 defensive pieces, but defending requires precise positions. A horse plus a soldier on the 10th rank wins against two advisors, or one advisor plus one elephant. This combination draws against 2 elephants. A horse plus two soldiers can win against one minor piece + one advisor + two elephants. With an extra advisor on the defensive side, it is a book draw. Two horses win against all 4 defensive pieces, or any combination of a minor piece plus 2 defensive pieces except cannon + 2 elephants. Cannon endgames A bare cannon, or a cannon with elephants, cannot win against a bare general due to insufficient material. Cannons need defensive pieces for cooperation, especially the advisor. A cannon needs only one advisor to win against two advisors, or a single elephant. Meanwhile, even with all 4 defensive pieces, it is a book draw against two elephants, one advisor + one elephant, one soldier + one advisor, or any minor piece. A cannon with all 4 defensive pieces needs at least an extra soldier to win against 4 defensive pieces. A bare cannon with a soldier on the 6th rank wins against any combination of 2 defensive pieces. A cannon + 4 defensive pieces + 2 unadvanced soldiers generally draw against one minor piece + 4 defensive pieces. But if the defensive side lacks a single piece, it is a book win. Horse+Cannon endgames This type of endgame is considered one of the more complex endgames. Commonly known book wins and book draws are: Horse + Cannon + 4 defensive pieces vs a minor piece vs 4 defensive pieces: A win if the minor piece is a horse (the attacking side does not need all 4 defensive pieces to win), a draw if it is a cannon. With the same combination of the two minor pieces and all 4 defensive pieces on both sides, one needs two extra soldiers for a book win. If both sides have 2 minor pieces and 4 defensive pieces, and the advantegeous side only has one extra soldier, then regardless of the combination of the two minor pieces, it is a book
