Errors & Warnings
Errors cascade from board desynchronization: once one move is misparsed or illegal,
every move after it is flagged too, because the internal board no longer matches the real game.
The first error listed is almost always the actual point of invalidity —
treat later errors as noise once you’ve fixed it. Amber warnings do not invalidate a game; they flag
notation the moves don’t quite support, or results that can’t be checked from the move list alone.
What this tool checks: that the RGN file is well-formed, that every move is legal
under IRF rules on the 5×5×5 board, and that the declared result matches the actual outcome
when the game ends in checkmate or stalemate. What it cannot check: whether the game was
actually played by the two named members as claimed. A legality check confirms a move sequence is
possible, not that it happened at the board. The IRF administrator may still investigate
submissions independently; see the Charter on
suspension and expulsion for falsified game results.
