class Empty : public Piece īool check_white_move (. ![]() Each nibble is also index in the table of singleton objects that operate on that piece type. You can't worry about performance and code for fun at the same time :)Ĭonsider having "nibbleboard" (or at least byteboard) instead of bitboard, where each nibble represents one piece type. The two sides are briefly called White and Black. Just add an abstract method tp the Piece class that returns a PieceType enum and switch on that. The Chess Pieces The great game of chess has two opposing sides, light colored and dark colored. So if you find that some important part of your algorithm that should really be in one place is scattered over multiple piece classes - use a switch statement. extensibility and modularity is not really an issue. On the other hand, it's unlikely that you will ever have to add new piece types or that you will ever be able to re-use one of the piece types in separation. Bishop - Moves any number of squares diagonally. This is not a question of advantages and disadvantages of different techniques: its about using the correct technique. Rook - Moves any number of squares horizontally or vertically. Classes and inheritance are used for representing abstractions and providing implementations thereof. Queen - Moves any number of squares diagonally, horizontally, or vertically. (Assuming you don't need bitboard-performance) King - Moves one square in any direction. Chess 101: All the Chess Piece Names and Moves to Know Written by MasterClass Last updated: 4 min read Though forms of the board game now known as chess have existed since the sixth century, it took nearly a thousand years for the pieces used in the game to reach their modern form. Staring at 2d boards got me thinking about the pieces & their movements. ![]() I’ve never gotten far into the game but it was surprising how enjoyable & instructive it was to watch great games re-enacted with insightful commentary. sum up the values of all pieces for a board, maybe sum up some kind of "position value" that depends on the piece (rook on an open line, things like that)Īdditionally, some of the pieces have "state" (a king can only castle if it hasn't moved before, a pawn can strike in passing if the other pawn just moved two squares) that only apply to one kind of piece. L ast year I got a bit back into chess thanks in part to discovering YouTube chess commentators like Agadmator.get the set of possible moves for each piece There should always be a white square at the closest right-hand side for both players. ![]() I never wrote a chess program, but I'd guess the most common operations would be things like:
