Tempo move
A move that, without adding or subtracting any possibilities, allows the opposite side to play as if the side making the tempo had not moved.
Two types of tempo moves can be distinguished:
- Waiting tempo move (pure tempo): A move can be skipped without affecting subsequent moves of the solution line.
- Zugzwang avoidance (impure tempo): A piece could play on a particular square at once, but it makes an intermediate move to avoid a lack of tempo move in the future. The move cannot be skipped.
Special cases of tempo moves are:
