4x4 Chess

Notation

This site uses Forsyth-Edwards Notation for positions and Algebraic Chess Notation for moves. Below is a summary of symbols that I use. Most are standard, except "♢" which was co-invented with Siegfried Hornecker.

Move annotation:
+	– Check
#	– Checkmate
!!	– The only winning (or the only non-losing) move
!	– The fastest win (or the fastest way to goal)
?	– Move gives away half a point
??	– Move gives away the whole point (losing move in a won position)
□	– The only possible move
♢	– The move wins and has equally good alternatives
☉	– Move leads to a reciprocal zugzwang
Game outcome (assuming the best play from both sides):
∞	– Unknown (position is not solved)
=	– Draw
+−	– White wins
−+	– Black wins
#5	– White mates in 5 moves
#−5	– Black mates in 5 moves
X5	– White wins, with checkmate or capture in 5 moves.
X−5	– Black wins, with checkmate or capture in 5 moves.
C5	– White wins, with checkmate, capture, or promotion in 5 moves.
C−5	– Black wins, with checkmate, capture, or promotion in 5 moves.
Z5	– White wins, with checkmate, capture, or a pawn move in 5 moves.
Z−5	– Black wins, with checkmate, capture, or a pawn move in 5 moves.
