Bot.cpp

This file contains the abstraction for finding the best move. It also acts as a consolidation point for all the different modules of the engine.

get_best_move

This function is the entry point for finding the best move. It first check the game stage and then calls the appropriate function to find the best move. If the game is in the opening stage, it calls the opening_move function. If the game is in the middle game stage, it calls the middle_game_x_thread function with a depth determined by the determineDepth function. If the game is in the endgame stage, it calls the middle_game_x_thread function with a fixed depth of 11.

std::string Bot::get_best_move(Board& board, char colour, int depth=-1) {
    if (this->game_stage == 'o') return Bot::opening_move(board.getFen(), colour);
    else if (this->game_stage == 'm'){
        int d = depth == -1 ? Bot::determineDepth(board) : depth;
        return this->middle_game_x_thread(d, board, colour);
    }else {
        return this->middle_game_x_thread(11, board, colour);
    }
}
