Discover chess puzzles

Discovery Chess Puzzles

Discovery is one of my favorites, helping to build tactical and strategic skills. Discovered attacks are dangerous, even the threat of a discovered check, or double check often brings a chess game to a sudden end.

Discoveries come in three basic flavors, double check, discovered check, and lastly attack check.

Double check, the most powerful, the moving piece gives check and in the process uncovers another check on the opponents' King by another piece while capture of the checking piece is not possible.

Discovered check happens when the opponents' King is attacked only by a piece along a line, whether it be a file, rank, or diagonal while the discovering piece is free to move about the chessboard to make threats of its own.

Discovered attack are slightly different in that the opponents' King is not directly involved. These attacks occur in the same manor as the other two attacks, usually targeting a piece of higher value instead of the King.

Surely this is black to move and black should play be3?
