Unmask a bishop, rook or queen while the moving piece makes a threat of its own: discovered attacks, discovered checks and the double check. This is a tactics course with 6 lessons and 60 interactive exercises, suited to players rated around 1100 (improving players). Every exercise is played on a real board with feedback after each move, there is nothing to install, and it is free.
Lessons in Discovered attacks
Double check – When the moving piece and the piece behind it both give check, no block or capture helps: the king has to move, and often it has nowhere to go.
Double check, part 2 – When the moving piece and the piece behind it both give check, no block or capture helps: the king has to move, and often it has nowhere to go. More positions, a little harder.
Discovered attacks – Move one piece out of the way and the bishop, rook or queen behind it attacks. The piece that moves can make a threat of its own, so two threats arrive at once.
Discovered checks – A discovered check is the strongest form: the king has to deal with the check, so the piece that moved is free to do anything, even take the queen.
