Normally, the winning process involves first winning the rook with the queen via a fork and then checkmating with the king and queen, but forced checkmates with the rook still on the board are possible in some positions or against incorrect defense. With perfect play, in the worst winning position, the queen can win the rook or checkmate within ...
[15] [1] In a less exotic case, it explains why trading rooks in the presence of a queen-vs-3-minors imbalance favors the player with the queen, as the rooks hinder the movement of the queen more than of the minor pieces. Adding piece values is thus a first approximation, because piece cooperation must also be considered (e.g. opposite-coloured ...
Once a metric is chosen, the first step is to generate all the positions with a given material. For example, to generate a DTM tablebase for the endgame of king and queen versus king (KQK), the computer must describe approximately 40,000 unique legal positions. Levy and Newborn explain that the number 40,000 derives from a symmetry argument ...
Without pawns, the queen normally wins but it can be difficult and there are some drawn positions (see Philidor position § Queen versus rook). If the rook has one pawn drawing positions are possible, depending on the pawn and the proximity of the rook and king. See Fortress (chess) § Rook and pawn versus queen. Otherwise the queen wins.
The white queen starts on d1, while the black queen starts on d8. With the chessboard oriented correctly, the white queen starts on a white square and the black queen starts on a black square—thus the mnemonics "queen gets her color", "queen on [her] [own] color", or "the dress [queen piece] matches the shoes [square]" (Latin: servat rēgīna colōrem).
Staunton style chess pieces. Left to right: king, rook, queen, pawn, knight, bishop. The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way.
q1 = q2*6 + r2. r2 gives the queen's position, so put it on the board. q2 gives the N5N code, so put the knights on the board (of course skipping over the bishops and queen). Starting with idn = 518, we get 518 = 32*16 + 6, and 32 = 5*6 + 2 so the bishop's code is 6, the queen's position is 2 and the N5N code is 5 with configuration -N-N-.
With the exception of the knight, each piece is abbreviated as the first letter of its name: K for king, Q for queen, R for rook, B for bishop, and P for pawn.As knight begins with the same letter as king, it is abbreviated as either N, Kt or KT, the first being the modern convention.
