Frequently asked questions (FAQ)

How good is the chess AI?

Our AI uses a valuation function based on material value and position. Easy (Depth 1), Medium and Hard (Depth 2 with opponent answer).

How do you win in chess?

The goal is to checkmate the opponent's king – then it is trapped and cannot move. A game can also end in a draw (stalemate), for example when the player to move has no legal move.

What special rules are there?

There are a few special moves: castling (king and rook move together), capturing en passant with a pawn, and promoting a pawn to a stronger piece when it reaches the last rank. The AI knows all these rules.

When does a game end in a draw?

A game ends in a draw when the player to move has no legal move and is not in check (stalemate). If no piece can checkmate the king anymore, the game also remains a draw.

Can I play against the computer?

Yes! Choose "AI White" or "AI Black" to play against the AI. The AI automatically moves according to your turn.

Can I undo moves?

In AI mode, the last AI move is undone. In 2 player mode, both moves are undone.

How does castling work?

Castling is a move in which the king and rook are moved at the same time. The king moves 2 squares towards the rook, the rook jumps behind the king. Prerequisite: King and rook must not have been moved, no pieces between them, king not in check.
