In chess, there are a number of ways that a game can end in a draw, in which neither player wins.Draws are codified by various rules of chess including stalemate (when the player to move is not in check but has no legal move), threefold repetition (when the same position occurs three times with the same player to move), and the fifty-move rule (when the last fifty successive moves made by both ...
The king can make a special move, in conjunction with a rook of the same color, called castling. When castling, the king moves two squares horizontally toward one of its rooks, and that rook is placed on the square over which the king crossed. Castling is permissible under the following conditions:
An illegal move [65] is a move not made according to a piece's possible defined movements [66] or made according to its possible movements but such that its own king is left or placed in check. [16] Furthermore, pressing the clock without making a move or making a move with two hands is considered and penalized as an illegal move.
In this diagram, the black king is on its sixth rank, but with Black to move it does not have the opposition. If the black king moves, the white king simply goes to d2 (best) or d1. If the pawn advances to d2, the white king moves to d1, and a draw results as above. [30]
(The game was a theoretical draw from before here until Black's 141st move.) Black could have claimed a draw after White's 136th move (or at any of the subsequent moves). Instead, the game continued and Black resigned on his 142nd move after White had achieved a forced winning position even though the right to claim a draw was still in effect.
An Austrian Attack line from the Pirc Defence has been analyzed out to a draw by threefold repetition. After the moves 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 c5 6.Bb5+ Bd7 7.e5 Ng4 8.e6 fxe6 9.Ng5 Bxb5! 10.Nxe6 Bxd4! 11.Nxd8 (diagram) Black can force perpetual check and so the draw by the following moves: 11...Bf2+ 12.Kd2 (first time) Be3+ 13 ...
If it gets to one of the squares marked with "x", the king can move next to the pawn and the rook can capture the pawn for a draw. Otherwise, the king needs to stay on the squares marked with dots: g7 and h7. The reason is that if the black king is on another rank, the white rook can check and then the pawn promotes and wins. For example, if ...
After this move, White cannot prevent the black king escaping the b1–h7 diagonal. The black king can play up the g-file to g6 and the white king has no option but to follow with opposition on the e-file to at least e5, otherwise the black king can escape to the third perimeter at f5 or f6. 83... Kg4 84. Be4. The black king can now escape to ...
