Lech Andrzej Pijanowski ([ˈlɛx ˈandʐɛj pijaˈnɔfski]; 26 July 1928 – 6 January 1974) was a Polish film critic, broadcaster, director, screenwriter and populiser of games.
Pijanowski contributed the game Lap, a development of Battleship, to A Gamut of Games, edited by Sid Sackson. In this game each player secretly divides an 8×8 grid of cells into four sectors of exactly 16 contiguous squares. Each player in turn gathers clues by asking their opponent how many cells in a particular 2×2 square belong to each sector. The first player who correctly deduces the opponent's setup wins the game.
