Tips for Direct Mate Problems Look at the “King’s field”, which includes the square the King is on, and the squares around the King. There are usually squares the Black King cannot legally move to because one of his pieces is there, or there is a threat from the White pieces. Find ways to attack the King, and the remaining squares around the King Chess Merit Badge © 2011

Tips for Direct Mate Problems The set of squares that the Black King can move to often gives a strong clue to the kind moves that will give checkmate. Bishop, Queen or Knight can cover diagonal squares. Rook or Queen cover squares in a row or column. A discovered check can cover a triangle next to the King in a single move.

Tips for Direct Mate Problems Look for the flight squares that the Black King can move to. The Black King may be able to move away, or forcing the King move to another square could create an opportunity to give checkmate. Chess Merit Badge © 2011

Tips for Direct Mate Problems Look at which pieces are pinned and where it may be possible to break the pin on a piece. Pins to the King prevent a piece from moving, and breaking the pin makes it possible to move that piece. Chess Merit Badge © 2011

Tips for Direct Mate Problems Look at possible checks to the White King from the Black pieces (or vice versa). Harassing checks can slow down or stop a checkmate attack. Chess Merit Badge © 2011

Tips for Direct Mate Problems Composed chess problems are often designed to hide the solution, so it may be necessary to look at some rather odd first moves (called the “key”). Odd key moves that give Black more freedom to move and open up many options, or moves that reduce the options for White moves, are valued by chess problem composers. Chess Merit Badge © 2011

Tips for Direct Mate Problems Analyze options in a methodical way, so that you do not miss the solution. Some first moves may have several responses, and each one needs to be analyzed. Chess Merit Badge © 2011

Tips for Direct Mate Problems Mate in two move problems can be solved by looking at all possible moves. For mate in three or more moves though, you will need to know some shortcuts you learn from practice in solving simpler direct mate problems. Chess Merit Badge © 2011

Tips for Direct Mate Problems When no other move seems to work, the composer may have implied a move, like castling or an en passant pawn capture. If the King and Rook are on the initial squares, assume that castling is possible. If pawns are positioned on adjacent files in row 4 or 5, assume that the first move could be to capture a pawn en passant. Chess Merit Badge © 2011

Chess Problems as Art The Knight’s Wheel problem as Art: The solution tells a tragic and heroic story The Black Knight stands by his King to the end, defending with every possible move from one threat after another, until the Knight ultimately overwhelmed.
