Getting Started

ChessKit is well covered by documentation. But anyway here you can find an example describing how to start working with ChessKit faster.

import ChessKit

let italianGameFen = "r1bqk1nr/pppp1ppp/2n5/2b1p3/2B1P3/5N2/PPPP1PPP/RNBQK2R w KQkq - 4 4"
let italianGamePosition = FenSerialization.default.deserialize(fen: italianGameFen)
let game = Game(position: italianGamePosition)

print("Number of available moves: \(game.legalMoves.count)")

game.make(move: "b2b4")
let evansGambitFen = FenSerialization.default.serialize(position: game.position)
print("Evans gambit fen: \(evansGambitFen)")

game.make(move: Move(string: "c5b4"))
let evansGambitAcceptedFen = FenSerialization.default.serialize(position: game.position)
print("Evans gambit accepted fen: \(evansGambitAcceptedFen)")

print("List of moves in game: \(game.movesHistory)")
print("List of pieces on board: \(game.position.board.enumeratedPieces())")
