Pawn (chess) Pawn (chess) The pawn (♙,♟) is the most numerous piece in the game of chess, and in most circumstances, also the weakest. It historically represents infantry, or more particularly, armed peasants or pikemen. Each player begins a game with eight pawns, one on each square of the immediately in front of the other pieces. (The white pawns start on a2, b2, c2, d2, e2, f2, g2, h2; the black pawns start on a7, b7, c7, d7. e7, f7, g7, h7.) Individual pawns are referred to by the on which they stand. For example, one speaks of "White's f-pawn" or "Black's
Chess and is provably less than 10, with a game-tree complexity of approximately 10. The game-tree complexity of chess was first calculated by Claude Shannon as 10, a number known as the Shannon number. Typically an average position has thirty to forty possible moves, but there may be as few as zero (in the case of checkmate or stalemate) or (in a constructed position) as many as 218. Chess has inspired many combinatorial puzzles, such as the knight's tour and the eight queens puzzle. The idea of creating a chess-playing machine dates to the 18th century; around 1769, the chess-playing automaton
