kriegspiel 1.3.2

Python hidden-information chess engine for Berkeley-family Kriegspiel variants

kriegspiel

Python game engine for hidden-information Kriegspiel referee rules.

Current scope:

• Berkeley Kriegspiel
• Berkeley + Any
• Wild 16

The package models the referee, not a UI. You interact with it by asking questions as KriegspielMove objects and reading KriegspielAnswer results.

Install

pip install kriegspiel

Quick Start

import chess

from kriegspiel import KriegspielGame, KriegspielMove, QuestionAnnouncement

game = KriegspielGame()

question = KriegspielMove(
    QuestionAnnouncement.COMMON,
    chess.Move.from_uci("e2e4"),
)
answer = game.ask_for(question)

print(answer.main_announcement)
print(answer.special_announcement)

game.save_game("game.json")
loaded = KriegspielGame.load_game("game.json")

KriegspielGame() defaults to Berkeley + Any for backward compatibility. You can still use BerkeleyGame explicitly, or pick a ruleset with ruleset=....

Wild 16 also has its own convenience entrypoint:

from kriegspiel import Wild16Game

wild16 = Wild16Game()
print(wild16.current_turn_pawn_tries)

Main Concepts

• KriegspielGame: the neutral public entrypoint for the shared hidden-board engine
• BerkeleyGame: backward-compatible Berkeley-named entrypoint for the same engine
• Wild16Game: Wild 16 convenience entrypoint over the shared hidden-board engine
• KriegspielMove: a player question, either a normal move or ASK_ANY
• KriegspielAnswer: the referee response, including move outcome, captures, special announcements, and variant-specific public metadata
